Diamond Education & FAQ

At Gadhiya Jewels, our policy is anchored on uncompromising ethics, conscious luxury, and complete supply-chain transparency. We exclusively craft and source high-purity (Type IIa) lab-grown diamonds, which represent the purest chemical form of diamond (accounting for only 1-2% of all mined diamonds). Produced in controlled technological environments powered by renewable energy, our diamonds involve zero open-pit mining, zero ecological destruction, and zero human exploitation. Every stone is cut and polished with master precision in our Surat ateliers.

Lab-grown diamonds are authentic diamonds cultivated above ground in high-tech laboratories. They begin from a natural diamond seed—a thin slice of crystallized pure carbon—and are grown through advanced CVD (Chemical Vapor Deposition) or HPHT (High Pressure High Temperature) methods, precisely replicating the natural subterranean heat and pressure of the Earth's mantle. Historically, traditional diamond mining has often involved human rights concerns, child labor risks, and habitat degradation. Lab-grown diamonds from Gadhiya Jewels are guaranteed to be ethically grown in certified units entirely free from these unfortunate practices.

Yes, absolutely 100% real. The Federal Trade Commission (FTC), GIA (Gemological Institute of America), and IGI (International Gemological Institute) legally and scientifically classify lab-grown diamonds as genuine diamonds. They are not diamond simulants like Cubic Zirconia or Moissanite. They have the identical chemical composition, isometric crystal lattice, refractive index (2.42), dispersion (0.044), and legendary Mohs hardness of 10. They pass every standard diamond thermal and optical tester and will sparkle with eternal brilliance for generations.

We eliminate all guesswork through our transparent, collaborative bespoke workflow. Before metal casting begins, our 3D jewellery artists provide a detailed CAD (Computer-Aided Design) model and multi-angle renders displaying the exact dimensions, prong placements, and profile of your jewel. Once you review and approve the CAD model, our Surat atelier initiates casting and hand-setting. Before we pack your order, we film high-resolution 360° studio inspection videos and macro photographs of your finished piece to ensure complete confidence that you receive exactly what you ordered.

Yes. Every piece from Gadhiya Jewels is accompanied by our Lifetime Craftsmanship Guarantee. This warrants that your jewelry is free of structural manufacturing defects and guarantees the stated precious metal purity (BIS Hallmarked 10K, 14K, 18K Gold or 925 Sterling Silver) and diamond authenticity. We also provide lifetime complimentary cleaning, prong security inspections, and professional polishing support at our atelier.

If you are seeking a special diamond cut (e.g., Old European Cut, Antique Cushion, Hexagon, Dutch Marquise, French Cut, or Portrait Cut), a specific carat weight, or rare color grade not currently listed on our website, our master diamond cutting atelier can custom-cut or source any stone to your exact specifications. Reach out to our Bespoke Diamond Concierge with your preferred carat, cut, and budget, and we will present hand-picked options with full certifications and 360° videos.

Yes. Gadhiya Jewels lab diamonds are certified by premier independent diamond grading labs, primarily IGI (International Gemological Institute) and SGL (Solitaire Gemological Laboratories). Each certified diamond has an inscription that matches the number on the laboratory certificate. You can enter this certificate number directly into the laboratory's online portal to verify carat weight, dimensions, cut grade, color, and clarity. *(Terms and conditions apply per carat category)*.

A diamond is termed "Eye Clean" when it has no inclusions, blemishes, or cloudiness visible to the naked human eye when viewed from a standard viewing distance of 6 to 12 inches under normal daylight conditions. Generally, diamonds graded VVS1, VVS2, VS1, and VS2 are naturally eye-clean. For SI (Slightly Included) stones, our master gemologists manually inspect every single gem to ensure any microscopic inclusions are positioned where they are undetectable without a 10x jeweler's loupe.

We ship items with premier trusted carriers including USPS, FedEx, Aramex, and DHL/DPD (which takes 7-8 days for express international courier delivery). If you require specialized, fully insured high-value delivery, we coordinate it through dedicated insured security logistics (which takes 20-22 days). Domestic parcels across India are dispatched via Blue Dart, Sequel Logistics, or Delhivery (taking 3-7 business days).

Once you place a loose diamond order from Gadhiya Jewels (whether it is an inventory-listed stone or a custom-cut order), it is NOT eligible for return, cancellation, or exchange under any situation, as diamonds are individual unique commodities allocated and cut specifically for your order.

For eligible standard catalog jewelry, returns are processed within 7 business days following receipt and quality inspection at our Surat facility. Please confirm with us in writing before shipping the return parcel. All return items must be in brand-new, unworn condition with original security tags, packaging, and gemological certificates covered by our return policy conditions.

Orders for standard catalog items can be cancelled within 24 hours of placement for a full refund. For custom-designed jewelry or bespoke loose diamond orders, cancellations can only be accommodated before 3D CAD confirmation and precious metal casting or diamond slicing begins. Once individualized production is underway, cancellation cannot be accepted.

When you go for a bath, swim in chlorinated pools, exercise, or apply lotions and cosmetics carrying chemical ingredients, immediately remove the jewelry from your body. Follow our trusted at-home cleaning routine to keep your jewelry looking as brilliant as the day you purchased it:

Yes, fine gold, platinum, and lab-grown diamonds do not tarnish, discolor, or lose their crystalline brilliance simply by being stored. To ensure pieces remain flawless in storage, store each jewel individually in a fabric-lined jewelry box or soft velvet pouch so diamonds do not rub against softer gold surfaces. Keep away from excessive humidity and direct sunlight.

Yes, Gadhiya Jewels offers free laser engraving on engagement rings. However, on Full Eternity Bands, we cannot perform inside engraving due to its open-gallery setting framework where diamonds encircle the entire ring circumference.

For inscriptions exceeding 12 characters or letters, a nominal customization fee applies per character. If there is insufficient shank space for your desired text, our client representative will guide you on the best layout before production.

We recommend three accurate methods to determine your ring size:

*We offer one complimentary ring resize within 30 days of delivery on eligible classic solitaires and standard bands.

Yes, absolutely. Gadhiya Jewels crafts a prestigious collection of men's fine jewellery, including solid gold Cuban link and rope chains, lab-grown diamond signet rings, eternity wedding bands, diamond stud earrings, bespoke cufflinks, and custom pendants engineered with modern luxury and generational durability.
