All these key aspects are boiled down to one figure. It also includes salience, to express the exceptionality or appeal of a gemstone. The system is fairly exhaustive regarding the visual quality of a gemstone, and it addresses the main aspects of rarity, another key trait of any gemstone. Our rating system combines comprehensiveness with simplicity. What does this new system offer that traditional gem grading systems don't? Our gemmological laboratory has the credibility and the independence to offer this rating service, which is open to the entire jewellery industry. With almost 100 years of experience in seeing the best gemstones in the world, we believe we have a very robust base to establish such a system. This is a problem for consumers and also industry leaders. To our knowledge, there has been no comprehensive and easy-to-understand rating system for coloured gemstones. We want to provide more orientation and comparability to purchasing coloured gemstones. Why have you decided to launch your own gemstone grading system?
