Stone Jewellery Buying Guide 2026: Types, 14K vs 18K Purity, Settings, Net Weight Billing & BIS Hallmarking

By Satyam, BlueStone Editorial

Stone jewellery represents the ultimate union of precious metallurgy and gemological artistry. Whether adorning a delicate gold engagement ring, an intricate chandelier earring set, or a statement temple necklace, studded stones transform classic gold into expressive, radiant heirlooms. Across India, the demand for stone jewellery spans everyday minimal diamond studs and colourful birthstone rings to regal polki, kundan, and navratna bridal sets. However, buying stone jewellery requires specialized technical knowledge that extends far beyond purchasing plain gold bullion. When jewellery is studded, buyers must evaluate not only the purity and mechanical strength of the underlying gold mount, but also the structural security of gemstone settings, the natural authenticity of every mounted mineral, and the precise mathematical calculation of net gold weight versus gross weight under Bureau of Indian Standards (BIS) billing rules. Selecting an overly soft gold karatage like 22K for intricate claw prongs can lead to loosened stones, while failing to scrutinize the itemized invoice can result in paying premium gold rates for decorative stone weight. This comprehensive 2026 buying guide provides an authoritative roadmap to navigating stone jewellery, comparing 14K, 18K, and 22K gold purities, exploring the full spectrum of precious and ornamental stones, analyzing setting architectures, detailing transparent invoice mathematics, and verifying BIS HUID and lab certifications.

Quick Checklist: Key Rules for Buying Stone Jewellery in 2026

• Optimal Gold Karatage: 18K gold (750 fineness) and 14K gold (585 fineness) are the engineering benchmarks for stone jewellery. They provide the necessary tensile strength and hardness to lock prongs, bezels, and channels permanently in place. Traditional 22K gold (916 fineness) is generally too malleable for faceted stones, posing a risk of claw deformation and stone loss under everyday impacts.
• The Spectrum of Stones: Fine jewellery incorporates natural diamonds, precious gemstones (rubies, blue sapphires, emeralds), semi-precious ornamental minerals (amethyst, citrine, garnet, topaz, peridot), organic gems (natural pearls), and simulated stones (cubic zirconia/American diamonds). Understand the Mohs hardness scale before selecting stones for high-wear pieces like rings and daily bracelets.
• Setting Architecture and Security: Bezel and flush (gypsy) settings offer maximum physical protection and zero snagging for active daily wear. Channel settings protect side stones in eternity bands, while classical prong (claw) settings maximize light transmission and stone fire for solitaire rings and pendant centerpieces.
• The Net Weight Billing Mandate: Under Indian Legal Metrology and BIS regulations, jewellers must strictly calculate the gold rate on the net gold weight (gross weight minus total stone weight). Never pay the gold rate on gross weight. All stone weights, stone prices per carat, and making charges must be itemized separately on the tax invoice.
• Mandatory BIS Hallmarking & HUID: Look for the three mandatory laser engravings on the precious metal mount: the triangular BIS mark, the purity grade (e.g., 18K750 or 14K585), and the unique 6-digit alphanumeric HUID code, verifiable instantly on the government BIS CARE mobile app.
• Gemological Lab Certification: Ensure that diamonds and precious gemstones are accompanied by authentic grading certificates from accredited independent laboratories such as SGL, IGI, or GIA, confirming natural origin, carat weight, color, clarity, and treatment status.

What Is Stone Jewellery and Why Does It Dominate Fine Gold Craftsmanship?

In fine jewellery terminology, stone jewellery refers to any precious metal ornament, cast in solid gold, platinum, or sterling alloys, that is artistically set, studded, or channelled with mineral gemstones, diamonds, pearls, or synthetic crystals. While plain gold jewellery derives its beauty exclusively from metalwork techniques such as die-striking, laser cutting, filigree, and hand-engraving, stone jewellery creates visual depth and chromatic brilliance through the interplay of reflected light, optical dispersion, and mineral color saturation.

Historically, India has been the spiritual and commercial cradle of gemstone craftsmanship. From the legendary diamond mines of Golconda to the historic gem-cutting hubs of Jaipur and Surat, Indian artisans pioneered complex lapidary arts centuries before industrialization. In Vedic traditions, gemstones were revered not merely for decorative luxury, but for astrological harmony, planetary energy, and spiritual protection. The Navratna talisman, representing nine sacred celestial stones set around a central ruby, exemplifies how gemstones were seamlessly woven into sacred cultural identity.

In contemporary 2026 styling, stone jewellery dominates both bridal troves and urban daily wardrobes. Modern women and men increasingly seek pieces that communicate personal stories: birthstone rings marking birth months, brilliant diamond clusters celebrating career advancements, protective evil-eye charm bracelets, and vibrant coloured stone pendants that elevate monochrome office attire. The fusion of traditional artisanal stone setting with advanced computer-aided design (CAD) allows modern jewellers to craft ultra-precise, low-profile settings that make stone jewellery comfortable, lightweight, and durable for everyday routines.

The Spectrum of Stones: Diamonds, Precious Gems, and Ornamental Stones in Fine Jewellery

When selecting stone jewellery, understanding the identity, durability, and optical characteristics of each mounted jewelry stone is vital. In the gemological world, stones are categorized by their mineral composition, crystal structure, rarity, and position on the Mohs hardness scale (ranging from 1 for talc to 10 for diamond). A stone’s hardness directly dictates where and how often it can be safely worn.

Here is how the primary categories of jewellery stones compare in fine craftsmanship:

• Natural Diamonds (Mohs Hardness 10): The undisputed king of gemstones, diamond is composed of pure crystallized carbon formed under immense geological heat and pressure. With a maximum 10 on the Mohs scale, diamonds are virtually scratch-proof and impervious to daily abrasions, only scratchable by another diamond. Their high refractive index (2.42) produces unmatched internal brilliance (white light return) and fire (dispersion of rainbow hues). Diamonds are the premier choice for engagement rings, daily stud earrings, and lifelong wedding bands.
• The Big Three Precious Coloured Gemstones (Mohs Hardness 7.5 to 9):
  • Ruby / Manik (Mohs 9): Red corundum colored by trace chromium. Exceptional hardness makes rubies ideal for daily rings and bracelets. Coveted for deep pigeon-blood red saturation.
  • Blue Sapphire / Neelam (Mohs 9): Blue corundum colored by iron and titanium. Highly durable, possessing remarkable adamantine luster, suitable for engagement rings and luxury brooches.
  • Emerald / Panna (Mohs 7.5 to 8): Green beryl colored by chromium and vanadium. While hard, natural emeralds feature natural internal inclusions known as jardin (garden) and are commonly treated with cedarwood oil to enhance clarity. Emeralds require protective bezel settings and gentle handling.
• Semi-Precious Ornamental Stones (Mohs Hardness 6.5 to 8):
  • Topaz (Mohs 8): Available in brilliant sky blue, London blue, and imperial golden hues, offering high transparency and excellent daily scratch resistance.
  • Amethyst and Citrine (Mohs 7): Purple and golden quartz varieties offering vibrant, durable color at an accessible price point.
  • Garnet and Peridot (Mohs 6.5 to 7.5): Earthy deep reds and lively olive greens, popular in contemporary artistic jewellery and nature-inspired cocktail rings.
• Organic Gemstones (Natural and Cultured Pearls, Mohs 2.5 to 4.5): Composed of calcium carbonate and organic conchiolin produced by molluscs. Pearls do not refract light like faceted crystals; instead, they exhibit a soft, iridescent glow known as orient. Because of their low surface hardness and porosity, pearls must be protected from perfumes, cosmetics, and abrasion.
• Synthetic and Simulated Stones (Cubic Zirconia / American Diamond): Lab-created zirconium dioxide simulating diamond sparkle. While offering high optical dispersion and modest hardness (8.5), CZ stones lack the thermal conductivity and permanent value of natural diamonds, and their facet junctions can abrade over years of wear.

Gold Karatage and Metal Purity: Choosing 14K, 18K, or 22K for Stone Jewellery

One of the most frequent dilemmas Indian buyers face is choosing the right gold karatage for stone jewellery. While traditional cultural instinct leans heavily toward 22K gold due to its high bullion content (91.6 percent purity), stone jewellery obeys strict mechanical and metallurgical principles that make lower karatages significantly superior for stone security.

Pure 24K gold is exceptionally soft and malleable, with a Vickers hardness of only 25 to 30 HV. Even 22K gold, while hardened by 8.4 percent alloying copper and silver, remains comparatively ductile (60 to 75 HV). Under the mechanical stresses of daily life, such as carrying grocery bags, turning door handles, or accidental knocks, delicate 22K gold prongs can bend outward by fractions of a millimeter. In a prong-set ring or pavé necklace, a minuscule shift in claw tension causes the mounted stone to wobble and eventually fall out.

To provide reliable stone retention, the global and Indian fine jewellery industry relies on two structural alloys:

• 18K Gold (75.0% Purity | 750 Fineness): The Luxury Benchmark: 18K gold blends 75 percent pure gold with 25 percent strengthening metals like copper, silver, and zinc. This metallurgical formulation boosts Vickers hardness to 120 to 140 HV, more than double the hardness of 22K gold. 18K gold delivers the ideal equilibrium: it retains an unmistakable, rich golden luster while providing rigid, spring-tempered claws that grip diamonds and gemstones permanently. It is the undisputed gold standard for fine diamond jewellery, halo cocktail rings, and designer pendants.
• 14K Gold (58.5% Purity | 585 Fineness): Maximum Daily Durability: Comprising 58.5 percent pure gold and 41.5 percent alloyed metals, 14K gold reaches a Vickers hardness of 130 to 160 HV. It is remarkably resistant to scratches, dents, and band deformation. For pieces subjected to heavy friction, such as daily office rings, tennis bracelets, and delicate huggie earrings, 14K gold offers unyielding structural protection at a sensible, budget-friendly price point.
• 22K Gold (91.6% Purity | 916 Fineness): Best Reserved for Heavy Kundan or Plain Gold: If you insist on 22K gold for cultural or investment reasons, restrict your stone choices to traditional Kundan or Jadau styles. In authentic Jadau jewellery, stones are not held by thin mechanical prongs; instead, they are seated in lac (natural resin) and locked by burnishing thick, pure 24K gold foil (kundan) around the stone’s edges. For modern faceted diamond or gemstone jewellery with open-back claws, 22K gold poses an ongoing structural hazard.

Precision Stone Settings: Prong, Bezel, Channel, Pavé, and Flush Mounts

The architectural setting of a piece of stone jewellery dictates two essential factors: how much light enters the stone to create brilliance, and how safely the stone is protected from impacts and daily snagging. Choosing the right setting requires balancing your lifestyle activity with your desired aesthetic.

Here are the primary stone settings engineered in modern fine jewellery:

• Prong (Claw) Setting: Maximum Brilliance and Fire: The stone is cradled in a metal cup and elevated above the band by three, four, or six narrow metal claws that overlap the stone’s girdle. Because the sides and pavilion of the gemstone remain open to ambient light, prong settings deliver spectacular optical performance, making them the classic choice for solitaire engagement rings and stud earrings. However, high prongs can snag on knitted sweaters, scarves, or pockets, requiring occasional prong tightness checks.
• Bezel Setting: Ultimate Protection and Sleek Contour: A custom-shaped collar of solid gold wraps completely (full bezel) or partially (semi-bezel) around the perimeter of the gemstone, overlapping its upper edge. The bezel acts as an impenetrable metal bumper, shielding the stone’s vulnerable girdle from chipping. It creates a seamless, modern profile that cannot snag on clothing, making bezel settings ideal for physicians, active professionals, and everyday rings.
• Channel Setting: Clean Geometry for Linear Stones: Gemstones are slotted side-by-side into a recessed groove between two parallel walls of solid gold, with no metal separating individual stones. Channel settings produce a continuous ribbon of uninterrupted sparkle while leaving the top surface completely smooth. This makes channel mounts the gold standard for eternity bands, tennis bracelets, and hoop earrings.
• Pavé and Micro-Pavé Setting: A Carpet of Light: Derived from the French word for paved, pavé settings embed dozens of small, brilliant-cut stones closely together across the metal surface. Microscopic beads of gold are raised from the base metal to hold each stone. Pavé work creates an opulent, shimmering surface that masks underlying metal, frequently used in halo ring surrounds, highway bands, and decorative pendant motifs.
• Flush (Gypsy / Burnish) Setting: Minimalist Low-Profile Elegance: A precision hole is drilled into the solid metal, and the gemstone is seated flush with or slightly below the surface. The surrounding metal is then burnished tightly over the stone’s perimeter. Because no part of the stone or metal protrudes, flush settings offer zero snag risk, making them exceptionally popular in modern daily bands, men’s diamond rings, and contemporary minimalist pendants.

Handcrafted Stone Jewellery Designs: From Everyday Minimalism to Statement Heirlooms

Stone jewellery encompasses a breathtaking diversity of categories, each serving distinct functional and aesthetic purposes across your wardrobe. Contemporary designers thoughtfully blend traditional motifs with clean geometric lines, crafting pieces that seamlessly bridge traditional ceremonies and modern professional environments.

Key categories of fine stone jewellery include:

• Stone Rings and Solitaire Bands: From multi-row highway bands set with sparkling diamonds to vibrant cocktail rings showcasing cushion-cut gemstones, rings represent the most intimate and expressive stone jewellery category.
• Stone-Studded Earrings and Huggies: Ranging from essential everyday solitaire studs and comfortable diamond huggies that click securely into place to dramatic chandelier drop earrings for weddings and evening celebrations.
• Stone Pendants and Statement Necklaces: Graceful floral cluster pendants, symbolic evil-eye charms, and tiered diamond necklaces that effortlessly frame collarbones and accentuate both western necklines and traditional sarees.
• Stone Bangles, Kadas, and Tennis Bracelets: Sleek oval-contoured hinged bangles studded with brilliant diamonds, flexible tennis bracelets featuring channel-set stones, and charm-holding link bracelets designed for layered wrist styling.

The Buyer Formula: Understanding Gross Weight vs Net Weight in Studded Jewellery

Perhaps the single most critical financial trap in purchasing stone jewellery is confusing gross weight with net weight. In plain gold jewellery, weighing the piece on a certified electronic scale reveals the exact amount of gold you are buying. In stone-studded jewellery, however, the total reading on the scale combines the weight of the gold mount and the weight of all embedded stones.

Because gold is traded at premium rates per gram (e.g., thousands of rupees per gram), paying the prevailing gold rate on the total gross weight of a studded piece means you are paying exorbitant gold rates for stones that cost significantly less per gram, or even for inexpensive glass, lac, or wax used in traditional settings. Historically, unscrupulous jewelers inflated profits by weighing studded ornaments together and charging the gold rate on the entire gross weight.

Under the Bureau of Indian Standards (Hallmarking) Regulations and the Legal Metrology (Packaged Commodities) Rules mandated by the Ministry of Consumer Affairs, this deceptive practice is illegal. Legitimate fine jewellers must follow a strict, transparent billing formula:

• 1. Gross Weight (Total Weight): The absolute total weight of the completed jewellery piece, including gold, diamonds, gemstones, pearls, and enamel, measured in grams on a certified precision balance.
• 2. Stone Weight (Tare Weight): The exact weight of all mounted stones, recorded in carats (where 1 carat equals exactly 0.20 grams or 200 milligrams) or grams. Every stone type (diamonds, coloured gems, pearls) must be categorized with its specific carat weight.
• 3. Net Gold Weight: The true weight of solid gold, calculated strictly as: Net Gold Weight = Gross Weight minus Total Stone Weight.
• 4. Gold Value Calculation: The prevailing day’s gold rate for the certified purity (18K or 14K) is multiplied ONLY by the Net Gold Weight. Under no circumstances should the gold rate be applied to the Gross Weight.
• 5. Stone Charges Itemization: Diamonds and gemstones are priced independently based on their certified quality parameters (carat weight, color, clarity, cut). These stone charges are listed as separate line items on the tax invoice.
• 6. Making Charges and 3 Percent GST: Making charges (craftsmanship costs) are calculated either per gram of net gold weight or as a transparent flat fee. Finally, the statutory 3 percent Goods and Services Tax (GST) is applied to the combined sum of the gold value, stone charges, and making charges.

Always examine your tax invoice before completing payment. If an invoice shows a single lump-sum weight without clearly deducting the stone weight from the gold calculation, refuse the purchase and demand a compliant, itemized tax invoice.

Essential Quality Checklist: BIS Hallmarking, HUID, and Gemstone Certification

Verifying authenticity is the cornerstone of purchasing fine stone jewellery in India. Because gemstones are permanently set into metal mounts, verifying metal purity and stone authenticity with the naked eye is impossible. Genuine fine jewellers substantiate their quality claims through two independent, legally enforceable verification pillars.

The first pillar is mandatory Bureau of Indian Standards (BIS) hallmarking for the gold mount. Since June 2021, the Government of India has made 6-digit alphanumeric Hallmark Unique Identification (HUID) mandatory for all gold jewellery sold across notified districts. When inspecting stone jewellery, use a 10x jeweler loupe to confirm three distinct laser-engraved hallmarks on the inner surface of the ring band, earring post, or necklace clasp:

• The Triangular BIS Logo: Certifies that the manufacturer is licensed and compliant with national hallmarking standards.
• Purity Grade and Fineness Mark: Indicates the exact gold content, stamped as 18K750 (18 karat gold containing 75.0 percent pure gold) or 14K585 (14 karat gold containing 58.5 percent pure gold).
• The 6-Digit Alphanumeric HUID Code: A unique tracking identifier assigned to that specific piece of jewellery at a government-approved Assaying and Hallmarking Centre (AHC).

You can instantly verify the authenticity of your stone jewellery by downloading the official government BIS CARE mobile application. Entering the 6-digit HUID code into the app reveals the registered jeweller name, the AHC center code, the date of hallmarking, and the certified metal purity, providing absolute transparency and tamper-proof provenance.

The second pillar is independent gemological lab certification for the mounted stones. The gold hallmarking code certifies only the precious metal alloy; it does not evaluate diamonds or gemstones. Therefore, fine stone jewellery must be accompanied by an individual authenticity certificate from a recognized gemological laboratory, such as the Solitaire Gemological Laboratories (SGL), the International Gemological Institute (IGI), or the Gemological Institute of America (GIA). The grading card specifies the exact 4Cs of the mounted diamonds (Carat weight, Color grade, Clarity grade, and Cut quality) or confirms that coloured gemstones are natural and untreated, protecting your investment for generations.

Styling Stone Jewellery for Daily Wear, Professional Office Attire, and Festive Celebrations

The captivating charm of modern stone jewellery lies in its dynamic versatility. Unlike heavy, ceremonial plain gold that is often locked away in bank vaults between weddings, thoughtfully chosen stone jewellery effortlessly transitions across diverse wardrobe settings.

Here is how to curate your stone jewellery collection for every occasion:

• Effortless Daily Wear and Casual Outings: Prioritize low-profile, ergonomic silhouettes that sit close to the skin. A pair of diamond huggie earrings or bezel-set solitaire studs adds subtle luminescence without catching on your hair or earphones. Pair them with a dainty 14K or 18K gold chain featuring a single floating stone pendant, or stack two slender diamond-accented eternity bands on your ring finger for an understated yet polished casual look.
• Professional Corporate and Boardroom Styling: In executive and corporate environments, jewellery should exude refined poise rather than distracting flash. Choose structured, architectural pieces with geometric symmetry. A brushed gold highway ring with subtle channel-set diamonds, a sleek diamond line pendant, or a minimalist stone-accented watch charm projects executive sophistication while pairing seamlessly with tailored blazers, silk shirts, and formal trousers.
• Festive Gatherings and Evening Celebrations: Festive occasions like Diwali, Eid, and family weddings invite expressive color, layered luxury, and luminous grandeur. Elevate a jewel-toned silk saree or embroidered lehenga with a multi-stone floral cluster pendant necklace, dramatic cascading drop earrings, and an open-work oval diamond bangle. Layering complementary coloured gemstones, such as deep green emeralds or rich rubies framed by sparkling diamonds, creates regal visual harmony that commands admiration in festive photographs.

Care, Maintenance, and Cleaning Protocols for Delicate Stone Jewellery

Fine stone jewellery requires gentle, informed maintenance to preserve its optical brilliance and structural integrity. Over weeks of daily wear, atmospheric dust, hand lotions, cooking oils, soaps, and perfume mists form a greasy film behind mounted stones, particularly underneath open pavilions, dulling their light reflection and fire.

Follow these safe, professional cleaning and care protocols at home:

• The Gentle Luke-Warm Water Bath: Fill a small ceramic bowl with lukewarm water and add two to three drops of mild, chemical-free dishwashing liquid or baby shampoo. Soak your diamond and hard gemstone jewellery (rubies, sapphires, topaz) for 10 to 15 minutes to loosen stubborn oils.
• Soft Baby Toothbrush Cleaning: Take an ultra-soft bristled baby toothbrush and gently brush around the prongs, bezels, and under-gallery of the stones. Never use stiff-bristled brushes, toothpicks, or metal pins, which can scratch gold surfaces or bend delicate prongs outward.
• Rinse and Dry: Rinse the jewellery thoroughly under clean running water, ensuring the sink drain is securely plugged with a mesh strainer. Pat the piece dry with a soft, lint-free microfiber cloth. Allow it to air-dry completely before storing.
• CRITICAL WARNING: Ultrasonic Cleaner Hazards: Ultrasonic cleaning machines use high-frequency sound waves to dislodge dirt. While highly effective for solid gold and untreated diamonds, ultrasonic cleaners are strictly dangerous for fractured or oiled gemstones like emeralds, tanzanites, opals, and pearls. The intense sonic vibrations can shatter internal crystal cleavages and strip natural conditioning oils from emeralds, causing cloudy fractures.
• Proper Storage: Gemstones possess different hardness levels. A loose diamond stored in contact with a gold ring or pearl necklace will severely scratch the softer metal and organic pearls. Always store individual stone jewellery pieces in separate velvet-lined pouches or compartmented jewellery boxes.

Common Stone Jewellery Buying Mistakes and How to Avoid Them

Even experienced shoppers occasionally make critical errors when investing in studded jewellery. Being aware of these common industry pitfalls safeguards your budget, protects your consumer rights, and ensures lasting satisfaction:

• Failing to Verify Net Gold Weight Deduction: The most expensive mistake is paying gold rate on the entire gross weight of the ornament. Always inspect the itemized tax invoice to verify that the stone weight in carats has been converted to grams and completely deducted from the gross weight before the gold value is calculated.
• Selecting 22K Gold for Delicate Claw Settings: While 22K gold has cultural appeal, choosing it for multi-stone prong rings or pavé necklaces frequently leads to loose or lost stones due to the natural ductility of high-purity gold. Opt for 18K or 14K gold for structural peace of mind.
• Neglecting Independent Lab Certification: Never rely on verbal retailer assurances that stones are natural diamonds or authentic gems. Insist on written, verifiable grading certificates from recognized independent labs like SGL, IGI, or GIA.
• Ignoring Setting Height for Daily Wear: High-profile prong settings with cathedral arches look breathtaking in display cases but can become daily annoyances by catching on clothing, vehicle seats, and bags. For daily active wear, choose low-profile bezel, flush, or channel settings.
• Buying Uncertified Treated or Synthetic Stones as Natural: Glass-filled rubies, synthetic hydrothermal emeralds, and synthetic moissanites are frequently sold in unorganized markets without proper disclosure. Ensure the certificate explicitly states natural origin with disclosure of any enhancement treatments.

Conclusion: Making an Informed Investment in Fine Stone Jewellery

Investing in fine stone jewellery is a deeply rewarding experience that harmonizes timeless precious value, personal self-expression, and exceptional artisanal craftsmanship. By prioritizing structurally resilient 18K or 14K gold alloys, choosing secure settings engineered for your lifestyle, verifying transparent net weight billing, and demanding mandatory BIS HUID and accredited gemological lab certifications, you guarantee that every ring, pendant, earring, or bangle you select remains a radiant, secure, and cherished heirloom for decades to come.

Frequently Asked Questions About Stone Jewellery

What is the difference between stone jewellery and plain gold jewellery?
Plain gold jewellery relies solely on polished, engraved, or textured gold alloys without any embedded stones, making its value direct to calculate based on metal weight. Stone jewellery is studded with diamonds, precious gems, semi-precious minerals, or pearls, introducing optical brilliance, color, and intricate setting architecture, requiring separate evaluation of net gold weight and stone authenticity.

Which gold purity is best for stone jewellery?
18K gold (750 fineness) is widely regarded as the best purity for stone jewellery, offering the ideal balance between high precious gold content, rich color, and strong mechanical rigidity to hold stones firmly. For heavy-duty everyday wear, 14K gold (585 fineness) provides even greater surface hardness and dent resistance.

How do jewellers calculate the price of stone jewellery in India?
Under Indian Legal Metrology and BIS standards, jewellers must calculate the gold price exclusively on the net gold weight (gross weight minus total stone weight). Stone charges are itemized separately based on their certified carat weight and quality. Making charges and 3 percent GST are then added to complete the invoice.

Can I wear stone jewellery every day without stones falling out?
Yes, stone jewellery can be worn daily with complete confidence if set in durable 14K or 18K gold using low-profile settings such as bezel, flush, or channel settings. Avoid high-prong settings for rigorous physical activities, and have prongs inspected annually by a fine jeweller.

How can I verify that a piece of stone jewellery is authentic?
Verify two independent certifications: first, check the gold mount for the three mandatory BIS hallmark laser engravings (BIS logo, karatage e.g., 18K750, and 6-digit alphanumeric HUID verifiable on the BIS CARE app); second, ensure the mounted diamonds or gemstones come with an authenticity certificate from an accredited lab such as SGL, IGI, or GIA.

Are ultrasonic cleaners safe for all stone jewellery?
No, ultrasonic cleaners are only safe for untreated diamonds, rubies, and sapphires. They should never be used on emeralds, pearls, opals, or tanzanites, as intense sound vibrations can expand internal crystal fissures and strip away natural cedarwood conditioning oils. Clean delicate stones using lukewarm water, mild soap, and a soft baby toothbrush.

What should I do if a stone becomes loose in my jewellery?
Stop wearing the piece immediately and place it in a secure pouch to prevent losing the stone. Do not attempt to bend metal prongs at home with pliers. Take the jewellery to an authorized fine jewellery store where a master craftsman can professionally tighten or reset the stone.
