An independent approach to gemmology.
GemAria brings together gemmological knowledge, observation, market understanding and commercial connections.
Understand the stone before its value
A precious stone has an identity, an origin, characteristics, a history and a singularity of its own. GemAria aims to connect the material, gemmological knowledge and the international market.
We work through lasting relationships based on trust, transparency, discretion and professionalism.

View of the profession
Understand the stone before considering its value. Say what is known, what is not, and what only a laboratory can establish.
To inform, to select, to connect.Our view of the market
The gemstone market is international, discreet and demanding. Information flows unevenly between producers, dealers, jewellers and buyers.
GemAria stands between these players with a clear role, without taking the place of independent laboratories, and without promising what a stone cannot deliver.
Every stone has a story. Let’s discover yours.
A stone to understand, to find or to sell: write to GemAria. Every request is handled in strict confidence.
