The Surat Heritage: Where Artistry Meets Advanced Diamond Science

For over a century, the historic city of Surat in Gujarat, India, has served as the undisputed diamond capital of the world. More than nine out of every ten diamonds cut and polished across the globe pass through the hands of Surat’s lapidary artisans. Situated at the very nucleus of this historic ecosystem in Mahidharpura, Raffle Diamonds has spent more than 5 years refining the art and science of loose diamond manufacturing.

Our story is one of continuous evolution. What began as a dedicated natural diamond cutting workshop has grown into a vertically integrated, dual-manufacturing powerhouse. Today, Raffle Diamonds combines centuries of hereditary gem-cutting intuition with modern cleanroom Chemical Vapor Deposition (CVD) and High Pressure High Temperature (HPHT) plasma reactors. By bridging earth-mined rare diamonds with sustainable laboratory synthesis, we provide international jewelry brands, wholesale merchants, and independent designers with an uninterrupted, ethically verified pipeline of exceptional diamonds.

Diamonds Direct From the Manufacturer: Eliminating the Middleman

In the traditional global gemstone trade, a diamond changes hands half a dozen times—from the mining pit or CVD growth reactor to rough auctions, primary polishers in Mumbai, secondary brokers in Dubai, Antwerp, or New York, and finally retail jewelers. At each transfer, markups of 5% to 15% compound, inflating the cost for the final designer while obscuring the true provenance of the stone.

Raffle Diamonds was built to dismantle this friction. When you partner with Raffle Diamonds, you deal direct with the manufacturer. Your loose stones and calibrated sieve parcels are cut, laser-faceted, polished, and certified within our Mahidharpura facilities. This direct-source pipeline unlocks several decisive commercial advantages:

Unbeatable Factory Pricing: Wholesale B2B rates directly pegged to Surat manufacturing costs, saving you 15% to 25% on inventory acquisitions.
First-Look Inventory Access: Immediate allocation of freshly polished CVD/HPHT solitaire batches and calibrated melee parcels before they reach international diamond bourses.
Rigorous Sieve & MM Consistency: Tailor-sorted parcels (-2, +2, +6.5, +11, +14) engineered for automated luxury watchmaking, pave halos, and tennis bracelet production.
Custom OEM Cutting: Dedicated bench lapidaries ready to execute bespoke CAD parameters, from antique Rose Cuts to elongated ratio Ovals and portrait cuts.

100% IGI & GIA Certification: Scientific Transparency Without Compromise

Trust is the foundation of our business. At Raffle Diamonds, every individual loose diamond from 0.30 carats up to 60.00+ carats is submitted to independent gemological laboratories—chiefly the International Gemological Institute (IGI) and the Gemological Institute of America (GIA).

Our gemologists verify that every stone is evaluated against strict international standards for the 4Cs (Carat, Color, Clarity, and Cut). Each certified diamond receives an indelible, microscopic laser inscription on its girdle corresponding directly to its digital grading report. Buyers can instantly verify certification details on public laboratory databases prior to dispatch, ensuring absolute peace of mind for both the jeweler and the end consumer.
