GIA stands for the Gemological Institute of America, which has been the most important diamond grading lab in the industry. It certifies diamonds based on the International Diamond Grading System, which measures the ‘4 Cs’ – Cut, Clarity, Colour and Carat weight, allowing them to evaluate the quality of over all diamond. Every single one of our diamonds is certified by the GIA (above 0.30carats).

The date on your GIA certificate, confirms the date that the diamond was graded by GIA.

No, we don’t sell any second-hand diamonds, allowing us to guarantee the quality of our diamonds and ensure that they’re ethically sourced.

Some stones that are not suitable for engagement rings may be suitable for other uses – such as being set in jewellery where the inclusions aren’t as visible – such as earrings or setting in yellow gold where the colour isn’t as noticeable.

Surface graining is something that is only visible under microscopic magnification and all diamonds have some form of surface graining.

This means that within the diamond there is a minute pinpoint within the stone that is too difficult to mark on the reference diagram because of its small size.

Because we source from such a high percentage of the global diamond market, some diamond manufacturers price there diamonds differently to others – essentially the items are identical, however, they are just priced differently.
