Designing a ring for someone I haven't met is like assembling a puzzle. It began with Craig's preferences for Koi's ring: he wanted a gemstone that was in the blue-green family, and her favourite colour was purple. That gave me a wide range of choices to offer him. He liked the powerful metaphysical properties of tourmailne so I began the search for a spectacular blue-green (Indicolite) tourmaline for the centre stone. While I was at Baselworld in Switzerland this year, I sourced some lovely Indicolite tourmalines. To help me understand Koi's style, he described her as Elegant – Sporty, whose symbol is a firefly. From the pictures of her that he had sent, I could see that her stunning beauty required a symmetrical and regal design, with a creative and light-hearted accent.

By combining pear-shaped diamonds and round amethysts as accent stones around the centre tourmaline, I was able to symbolize fireflies and also incorporate Koi's favourite purple colour.
