Diamonds & Special Stones
Rough and polished diamonds sourced from Kimberley Process compliant mining regions — with GIA/IGI certification pathways, investment-grade parcels, and secure global logistics.
Overview
Diamonds are the world's most recognized gemstone and a cornerstone of investment-grade precious stone portfolios. We source both rough and polished diamonds from compliant mining regions across Africa, Canada, Russia, and Australia. All rough diamonds are accompanied by Kimberley Process Certificates (KPC) to ensure conflict-free provenance. Polished diamonds are available with GIA, IGI, and HRD laboratory certification. We supply investment-grade stones, commercial parcels, and large individual stones for qualified buyers, jewelers, and institutional clients. Special stones — including rare fancy colored diamonds, Type IIa diamonds, and historically significant stones — are available on a case-by-case basis through our sourcing network.
