Follow a lab-grown diamond through eight steps — from a single carbon seed to a certified, finished stone.
A sliver of real diamond, placed inside the reactor — it carries the exact structure the new crystal will copy.
In a glowing plasma of carbon gas, atoms settle onto the seed, layer by layer. The same crystal a mine takes a billion years to make.
Removed as a raw, blocky crystal — chemically and optically identical to a mined diamond, just without the mine.
Scanned and modelled to plan the cut that returns the most brilliance from every carat.
Lasers and wheels establish the table, the girdle and the facets that give a diamond its geometry.
Each facet is polished until light travels cleanly through the stone — the moment a shape becomes a diamond.
Independently graded and certified by IGI or GIA for cut, colour, clarity and carat.
Set into finished pieces or supplied loose to the trade across the USA, UK, UAE, Canada and Australia.
Certified lab-grown diamonds — loose or set, ready to ship from Surat.
