German Precision. Indian Artistry.
Since 1980, crafting brilliance in the heart of Pondicherry
Four Decades of Diamond Mastery
In January 1980, a handshake deal in Zurich set the course for what would become India’s most distinctive diamond enterprise. What began with two abandoned grinders under palm trees in Pondicherry has grown into a facility that has perfected over 5 million brilliants.
Aditi Diamonds is the Indian production arm of Diamantschleiferei Michael Bonke GmbH — currently the only German company cutting diamonds at industrial scale in its own facility. With over 40 years of expertise, we unite European precision standards with Indian craftsmanship.
