Our Story

A Legacy Carved
in Light & Stone

Founded in 2016 in the diamond capital of the world, Surat, Navratna Diamonds has been transforming raw brilliance into wearable art for nearly a decade. Every piece we craft carries the soul of our artisans and the precision of modern craftsmanship.

We believe a diamond is more than a gem. It is a promise, a memory, a milestone. That belief drives everything we do.

CVD Technology

Grown Atom
by Atom

Our diamonds are created through Chemical Vapor Deposition, the same process nature uses, accelerated in a controlled plasma chamber. Pure carbon builds layer by layer into a flawless crystal, chemically and optically identical to earth-mined diamonds.

01
Diamond Seed

A thin diamond wafer placed in the growth chamber as the foundation.

02
Carbon Plasma

CH₄ & H₂ gases ionized into plasma at 900°C to 1,200°C.

03
Crystal Growth

Carbon atoms crystallize layer by layer over weeks into a pure diamond.
