After several years of working as a gem cutter at the heart of the Antwerp diamond industry, the founder Mr. Stefaan Van Oppens decided that it was time to expand with a new wholesale in 1995.  


In 1997 the company moved to a new address where it rapidly grew in standards, quality and as always, with a service to be trusted. 


After several years, it was yet again time to allow the company to grow so in the winter of 2013 we moved again to our new address: Vestingstraat 13. 

In 2014 we have joined the International Colored Gemstone Association (ICA), for which we are also the Ambassador to Belgium.

In 2020 we joined the Responsible Jewellery Council, RJC.


Through the years we have become a trustworthy international partner for jewelers and traders, with the ability to supply gem stones and in the possession of our own in-house lapidary.


Our mission is to help our clients to find the perfect gem that also meets our high standards and quality.




We are a registered diamond company under number 8847. Check here for registered diamond companies.
