Sell Your Jewellery

At Mint Valuation & Consultancy, we are interested in buying high-value items, whether diamonds or other precious coloured gems for sale, or precious watches and fine art.

We buy one carat and larger white and colour diamonds, sapphires, rubies, emeralds & alexandrites. Signed pieces, such as Tiffany, Cartier, Van Cleef & Arpels, Harry Winston, David Webb, Mauboussin, Boucheron, J.E. Caldwell & Bulgari fetch the highest prices.

In particular, we are looking for jewellery from the Victorian, Art Nouveau, Art Deco, Retro and Art Modern periods.

Not for the world. Why, man, she is mine own, And I as rich in having such a jewel As twenty seas, if all their sand were pearl, The water nectar, and the rocks pure gold.
