Dialmaz is a certified, natural diamond jewelry manufacturer in Surat—the city that cuts and polishes more than 90% of the world’s diamonds. This guide covers why Surat matters so much to the global diamond trade, how Dialmaz manufactures certified natural diamond jewelry here, and what individual buyers and wholesale retailers should know before ordering.

Why Surat Is the World’s Diamond Cutting Capital

Surat, in India’s Gujarat state, cuts and polishes over 90% of the world’s rough diamonds—nine out of every ten diamonds set into jewelry anywhere in the world, from a New York engagement ring to a Dubai bracelet, were processed here. What started as a small trade in the 1960s has grown into a global industry employing over a million people directly and indirectly, supported by advanced laser cutting technology alongside traditional craftsmanship. The city is also home to the Surat Diamond Bourse, one of the world’s largest diamond trading facilities.

This concentration of skill and infrastructure is exactly why a diamond jewelry manufacturer based in Surat can offer something harder to replicate elsewhere: direct access to the world’s largest pool of diamond-cutting expertise, without the added cost of importing already-cut stones from a separate hub.

Certified Natural Diamond Jewelry Manufacturing in Surat

Dialmaz manufactures using natural diamonds exclusively—never lab-grown or synthetic—sourced conflict-free under the Kimberley Process and independently graded by GIA or IGI for cut, color, clarity, and carat weight. Certificates are available on request for every stone above roughly 0.30 carats, verifiable directly with the grading lab.

1. Diamond Sourcing and Certification

Natural, certified diamonds are sourced and graded before entering production, taking full advantage of Surat’s role as a global rough-diamond trading hub.

2. Design and CAD Modeling

Every piece starts as a 3D CAD model, letting buyers and retail partners approve stone placement, band width, and metal weight before physical work begins.

3. Casting, Setting, and Polishing

The CAD model is cast in 18K gold, 22K gold, or platinum, diamonds are hand-set using prong, pave, bezel, or channel settings; and each piece is polished and quality-checked before dispatch.
