Sell Your Diamonds with Confidence
Certified or uncertified, loose or set — we buy all diamonds. GIA-trained experts ensure fair, transparent valuations at competitive UK prices.
Selling a diamond can feel daunting — especially without a GIA certificate or when the piece holds sentimental value. Our GIA-trained gemologists assess every stone individually, considering cut, colour, clarity, carat weight and current market demand.
We buy loose diamonds of all shapes — round brilliant, princess, oval, emerald, cushion and more — as well as diamond rings, earrings, pendants and tennis bracelets. Certified stones from GIA, IGI and HRD are valued at a premium, but uncertified diamonds are equally welcome.
Unlike pawnbrokers or high-street jewellers who offer low trade-in prices, we specialise in diamonds and pay fair market rates. Every assessment is recorded on camera so you can see exactly how we grade your stone.
