About ten years ago, I started to buy grey stones. No one really wanted grey stones then, I mean, they were grey. That was until they saw them made into beautiful pieces of jewellery. Now grey is the hottest colour in gems. The best greys are spinel, natural, unheated tanzanite and tourmalines like these three beauties. We’ve not decided what to do with them yet, maybe you could have a say. Obviously I’m thinking cocktail rings, but that’s just me. @stephenwebsterjewellery
