The rough comes first

We purchase laboratory-grown rough and examine the material before deciding how to cut it. Shape, visible features and the intended finished stone all belong in that conversation. These photographs show actual material and people in our Surat workshop.

Decisions at the bench

Planning gives the team a direction. The physical work calls for care at every stage, from mounting and shaping through polishing. Our photographs show the equipment and handwork behind those steps; they are not a substitute for viewing the specification of an individual stone.

Look closely at the result

Close visual inspection is part of our internal quality control. Independent grading is a separate service performed by a grading laboratory where requested or supplied. If you are sourcing for a jewellery collection, tell us the shape, size, appearance, quantity and documentation you need so we can discuss the right material.
