Our Story
In January 1980, a handshake deal in Zurich, where a small diamond-cutting factory in southern India changed hands.
The deal included two abandoned grinders, a couple of sanding pliers, dops and other small equipment rusting away in Pondicherry.
The buyer was less a businessman and more an adventurer from the Bavarian Forest, whose great love was philosophy.
15 years later: two cutting machines had become more than 100, producing more than 1000 diamonds a day.
Business expanded: diamond cutting gave way to jewellery, then pearls, then CVD synthetic diamonds, and finally gemstone polishing — six distinct verticals under one roof.
Pondicherry
On the Bay of Bengal, 130 km south of Chennai, lies the idyllic colonial city of Pondicherry — our home since 1980. With its tree-lined boulevards, French colonial architecture, and vibrant cultural heritage, Pondicherry provides the perfect setting for a craft that demands both precision and artistry.
Auroville
8 km from Pondicherry is probably the most extraordinary social experiment of all: Auroville — the City of Dawn. Founded in 1968, this international township embodies the vision of human unity and sustainable living. The Matrimandir, its golden meditation sphere, stands as a beacon of consciousness at its heart.
