How to Sell Certified Diamonds in Geneva: The Essential Valuation Guide

Geneva has long stood as a historic capital of international gem trade and private wealth management. When selling a certified diamond or fine heirloom piece, working directly with accredited gemologists ensures maximum valuation based on real-time global markets.

Understanding the Global Diamond Valuation Standard

Unlike standard gold jewelry priced solely on metal weight, high-carat diamonds (1 carat, 2 carats, 5 carats and above) derive their value from the international Rapaport Diamond Report. Every stone submitted to our Geneva advisory is examined under standardized laboratory daylight, evaluating color grades from D to Z and clarity grades from Flawless to Included.

The Importance of Recognized Laboratory Reports

Certificates issued by premier laboratories such as the Gemological Institute of America (GIA), HRD Antwerp, or the Swiss Gemmological Institute (SSEF) confirm the natural, unenhanced origin of your gem. Even without an existing report, our senior gemologists perform on-site scientific testing to verify fluorescence, laser inscriptions, and structural purity.

Discreet Execution and Immediate Settlement
