Masterfully Crafted CVD Diamonds

From Seed to Masterpiece

Our fully integrated manufacturing unit in Surat oversees every step of the journey, ensuring uncompromising quality control from the initial CVD growth cycle to the final polish.

🔬

1. Seed Selection

We begin with the purest diamond seeds, meticulously inspected to guarantee that the resulting growth forms a perfectly structured carbon lattice.

2. CVD Growth

Placed in state-of-the-art plasma reactors, carbon-rich gases are deployed. Atom by atom, the diamond grows under precise temperature and pressure over weeks.
