We go above and beyond the current standards to offer Conflict Free Diamonds that have been selected for their ethical and environmentally responsible origins.

When I moved from Italy more than two decades ago, I knew no one in the jewellery industry.
Coming from the diamond mining industry, I just fell in love with the creative process of making jewellery.
I came to realize over years that if I could bridge the gap between being creative and competitive at the same time, that I will be successful.
We have a unique ‘Outsider and Insider’ approach to the finest diamonds and diamond jewellery business.
As part of our commitment to environmental responsibility, our fine rings is crafted form precious metals supplied by the most reputable and accredited refineries company in South Africa, and arrives in our distinctive, eco-friendly packaging.
