Certificates and Appraisals

GIA Certificates

All our diamonds have been thoroughly inspected and graded by the Gemological Institute of America (GIA), and are accompanied by their own GIA certificate, which covers the diamond’s characteristics or 4C’s – Carat, Cut, Colour, Clarity – and a visual diagram of the diamond’s proportions. Every diamond over .30ct is also laser inscribed for identification purposes.

Gemological Institute Of America (GIA)

The Gemological Institute of America (GIA) is one of the most respected and recognised diamond laboratories in the world, and diamonds that come with GIA certificates are the most highly valued. They are guaranteed to be graded reliably and consistently, by three to six separate gemmologists.

Insurance Appraisals

All loose diamonds, diamond rings and jewellery purchased from Diamond Exchange come with an appraisal for insurance purposes.

The insurance appraisal states the approximate retail replacement value of the item calculated according to the current retail marketplace. It also includes a description and photo of the item, as well details of the diamond such as carat weight, colour and clarity .

In the case of any loss, theft or damage, this insurance appraisal ensures that your insurance company will give you an equivalent replacement for the item.

For some extra peace of mind above and beyond your home & contents policy, consider our Q Report Insurance Policy.
