Our Story

Jeremy discovered that people wanting to sell their gems and jewellery didn't have a platform to do so. They could try auction but could realistically only get about 1/4 of the retail value which was the same as selling back to anyone in the gem and jewellery industry. The highest price one can expect from pre-owned gems and jewellery is about half the retail value. GemDiam was born to help those wanting to sell their gems/jewellery to get a fair price which is around half the retail value. GemDiam enables the seller and the buyer to get a fair price. The security of buying from GemDiam is that all the items have been checked and passed by The Gem Lab, one of South Africa's leading gem testing labs based in Cape Town.
