Ethical Sourcing of Rough
Our supply chain begins with ethically mined rough diamonds from partner miners in compliance with Kimberley Process regulations.

Rough diamonds are polished at our Surat facility. They are graded by GIA or IGI, then shipped securely via Brinks or Malca-Amit to wholesalers worldwide.
