Gübelin has launched what it describes as the first-ever rating system for coloured gems, which the brand hopes will provide a method to categorise coloured stones similar to the way diamonds are currently rated. Called Gübelin Points, the system looks at three factors: quality, rarity and salience, which considers what makes a gemstone exceptiona­l, with the hope that connoisseu­rs will be able to buy jewellery with added confidence.
