Diamond certification

Certified diamond dealer

Buying a diamond is a significant purchase and you should do everything you can to protect that purchase. You should always deal with a certified diamond dealer and ensure the relevant paperwork is made available to you.

Authenticity

A diamond certificate, also known as a diamond grading report, is an easily understood document prepared by an expert gemologist that describes the key characteristics of a diamond. A certificate from a gemological laboratory verifies the quality of a loose diamond and allows non-experts to make educated diamond buying decisions easily and without confusion or danger of misrepresentation.

The report doesn't tell you how much a diamond is worth (that is a ‘valuation’). Instead, it attests to the authenticity of a diamond using an internationally recognised system and provides a reliable and accurate report of its Carat weight, Colour, Clarity, and Cut.

Both Natural and Lab grown Diamonds are graded in exactly the same way.

Whenever you’re dealing with diamond jewellers in Sydney or anywhere in the world, ensure that this certification is available, whether you are buying loose retail or wholesale diamonds. This will give you the confidence you need to make a wise investment.

All diamonds sold by Diamond Emporium include detailed diamond certification from the Gemmological Institute of America (GIA), IGI International Gemological Insitute (IGI), Gem Certification & Assurance Lab (GCAL), the Diamond High Council of Belgium (HRD) or AGS Laboratories™ (AGS).

If you have any questions about these reports or buying diamonds, be it natural or lab grown, please get in touch with us and one of our jewellers can assist.
