The centre diamond photographed is a 1.2ct natural Canadian diamond sourced through the Canadamark programme. These natural diamonds are all conflict free, responsibly mined and fully traceable from the mine / origin to the cutter polisher and then direct us. We usually source our centre stone diamonds on an individual basis with the client according to their preferences and budget and can therefore adapt the size of the centre stone.  We primarily offer natural Canadian diamonds but in some of our pieces we can also offer Diamond Foundry lab grown.  Please get in touch for a bespoke consultation to select an alternative centre stone in this ring.
