Cadby & Co are a family business that specialise in using old cut diamonds and fine gem stones. Deborah Cadby’s designs and skills in making are combined with Jeff Cadby’s many years of dealing in antique jewellery. Together they are creating a beautiful collection of jewellery, using certified diamonds and coloured stones set in 22ct gold for its rich warm colour and platinum for its elegant, steely subtlety.

Unique hand cut stones have a nature of their own, with irregualar shapes, unusual dimensions and uneven facets. Each piece of jewellery is designed to suit the stone.

“Soft and tactile, simple and elegant, reminiscent of jewellery from ancient times recreated into modern design.” 


Many of our diamond and coloured stones are certificated by the British Gemmological Institute, GIA or other leading gemological laboratories. 

As members of the London Diamond Bourse we ensure the highest of standards and where all our members are required to adhere to the Kimberley Process and provide annual certification to validate any trade in conflict diamonds.

“Buying a stone or jewellery from a member of the London Diamond Bourse assures that the goods purchased are from a vetted professional of good standing who is accountable  to  the  industry  for   their  business  dealings.”
