Our Stones

We have always ensured that our diamonds are conflict-free. We only purchase them from legitimate sources that we know and trust. We’ve been following this responsible practice since we stated business in 1990’s.

Certified diamonds are diamonds that have undergone quality analysis by a trusted gemmological laboratory such as GIA (Gemmological Institute of America) and have been issued with an independent laboratory report. The GIA laboratory has the most sophisticated equipment, and they provide the most consistent gradings.  An added bonus is that Certified diamonds usually have a laser inscription for identification.

Non-Certified diamonds are still graded with the same quality analysis as certified diamonds, they just don’t have an independent certificate.  Because of the cost of certification, Non-certified diamonds may represent better value for money.  At Stones, whether a diamond is certified or not, you will always receive a valuation detailing that gemstones details.

The reality is that most of the diamonds we sell are not certified.  For jewellery containing lots of small diamonds, it is a practical impossibility to certify all of the stones.  Only 50% of diamonds over 0.50cts are GIA certified. 

We have established and trusted relationships with suppliers in the UK, Belgium , Israel and Germany and we only work with the best established suppliers who confirm to all the legal frameworks set out by the international jewellery industry.
