Madestones is currently the largest European producer and distributor of lab-grown diamonds. It is an initiative from Thierry Silber who has 42 years of experience trading diamonds in Antwerp-Belgium. Thierry started to sell lab-grown diamonds alongside mined diamonds in 2009 and created in 2015 the Madestones brand that markets lab-grown diamonds and lab grown diamond jewellery.
Madestones, round and fancies lab-grown diamonds, range in size from less than 0.01 carat to over 5 carats, with colour ranging from D to K and the clarity from Internally Flawless to SI2. Besides timeless whites, we offer spectacular colours like pink, blue and yellow priced at a fraction of their mined counterpart. Importantly, most of our lab-grown diamonds larger than 0.30ct are certified and laser inscribed. It is clearly stated that they are lab-grown diamonds.
Quality of service and product are extremely important to us. We won the PJ award for the Best Supplier of Precious Metal and Stones 2018 in the UK.
