Services
Four decades of expertise, distilled into four practices.
01
Polished Diamond Trading
Active inventory of GIA-certified rounds and fancies, 0.30ct to 10ct+, sourced from the world's leading manufacturers.
02
Bespoke Sourcing
Discreet procurement of rare, fancy-coloured and large stones to exacting specification — typically within 14 days.
03
Grading & Consultation
Independent gemmological assessment by senior graders, supporting investment, estate and acquisition decisions.
04
Global Logistics
Insured worldwide shipping through Brinks and Malca-Amit with full chain-of-custody documentation.
The Craft
Every stone considered. Every detail recorded.
Our senior graders examine each diamond against its certificate — verifying proportions, fluorescence and optical performance before it enters our inventory. The result is a curated catalogue you can trust without seeing it in person.
