With more than 50 years history in the diamond and jewellery business, our roots go back in time in the same region who saw the Etruscans becoming the first professional jewellers in the world some 3,000 years ago. We are based in Arezzo (Tuscany), the heart of Italian culture and arts where hundreds of skilled manufacturers still carry on the tradition making the most beautiful Italian jewellery.

Buying diamonds online may sound risky and complicated but for 18Carati this is a won challenge and we are the reliable online diamond merchants who started selling jewellery and diamonds over the internet more than 15 years ago.

Our diamonds are certified by the most prestigious laboratories such as IGI, GIA and HRD and for every single stone we provide copy of the certificate and real photos beforehand so that there will be no surprise when you purchase your diamond from us. Whether it is for a solitaire ring or as a form of investment to be kept in blister, choosing a diamond requires experience and specific knowledge that is not within everyone's reach and that's why we are always keen on providing full pre-sale assistance.

We sell at the lowest possible price because we deal directly within the most important diamond exchanges in the world, avoiding middlemen's costs therefore passing much of the benefit to our customers.
