Frequently Asked Questions


Q. Should I buy a certified or non-certified diamond and what is the difference?
A. 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.  Over 99% of our diamonds over 0.50cts are GIA certified.  For more information regarding diamond certification, press here.

Q. I’ve been told that an emerald is soft and can easily be damaged.  Can I wear an emerald in my engagement ring?
A. Yes, you can.  Contrary to a commonly held belief, emeralds are quite a hard gemstone.  With a hardness of 7.5 to 8, they are not easily scratched.  Emeralds do have inclusions however and some break the surface of the gemstone.  These characteristics can make emeralds more prone to chipping or breaking on impact.  Worn with normal care, they will give you a lifetime of pleasure.  For more information on the hardness of gemstones, press here.
