About Us

Silverton is a trading name of D. I. Silverton Ltd which has been trading since 1975, a well-respected and continuously successful wholesale jeweller and diamond merchant which has traded from one address ever since. Silverton is a family business offering a comprehensive range of precious and semi-precious gemstones, loose diamonds, and finished jewellery in both 18ct Gold and Platinum. We supply retail jewellers, working jewellers and manufacturers and other members of the trade.

We are members of the London Diamond Bourse, the only diamond trading floor in the UK and a member of the WFDB. Silverton trades only in natural, polished diamonds which are sourced from some of the world’s leading diamond cutters in Israel, Antwerp and India, where rough diamonds have been ethically sourced from conflict-free countries in line with the Kimberley Process.

We stock a huge range of Gemstones including Diamond, Ruby, Emerald, Sapphire, Aquamarine, Tanzanite, Tourmaline, Garnet, Amethyst, Topaz and Spinel. From small stones for manufacturing in Ruby, Emerald and Sapphire, calibrated sizes in all gemstones, and one-off larger stones, we have the gemstones for you.

Our range of diamonds includes small diamonds in calibrated sizes for manufacturing and repair, individual and matched pairs/sets of diamonds in all shapes from 0.05ct-1.00ct+, and a large inventory of both certificated and non-certificated diamonds from 0.25ct to over 10cts.

We also stock a large range of Natural Fancy Colour Diamonds, which is one of our specialist areas of expertise, and are members of both the NCDIA (Natural Coloured Diamond Association) and FCRF (Fancy Colour Research Foundation). Our stock includes melee sizes of natural pink and yellow diamonds, and stones from 0.05ct in colours including Green, Pink, Yellow, Orange, Grey and Brown in all shapes. All our diamonds are carefully sourced for how they look, and we prize brilliance and ‘make’ above all else.
