Diamond laboratory certificates are highly recommended when selling a diamond but not necessary. If you have any diamond certificates, let us know or bring them in to help us give you the highest price for your diamonds. If you can’t visit us in-store, email a copy of your diamond certificate and we can give you an initial valuation based on the information in your certificate.

Do you need your own diamond certificate? There are many laboratories issuing diamond grading certificates, some reputable and reliable and others not so. We highly recommend laboratory certificates from independent bodies such as the Gemmological Institute of America (GIA) – the creator of the diamond grading system in 1931 and a non-profit organisation and Gem Studies Laboratory (GSL) – over 20 years experience in Australia and endorsed by the Gemmological Association of Australia (GAA).

What makes up the value of your diamond?

When selling your diamond the value will be determined by the” 4 Cs” of a diamond – Carat Weight, Colour, Clarity and Cut.

Carat Weight – this is the measure of weight of a diamond. The more Carat weight the more rare and valuable the diamond is.

Colour – diamonds come in many varieties of Colours such as white, yellow or pink. In a white diamond, the presence of a yellow tint will lower the value. The less body Colour in a white diamond, the more true Colour it will reflect and thus the greater its value.

Clarity – this refers to the degree to which there are “imperfections” (i.e. inclusions and birthmarks) in a diamond. The less inclusions in a diamond the greater the value of your diamond.

Cut – the Cut of a diamond refers to its proportion, symmetry and polish. The beauty of a diamond depends probably the most onCut than the other factors.

There is also one more important factor which helps determine a diamonds value – shape. Diamonds come in many shapes, the traditional shapes such as Round Brilliant Cut and Princess Cut diamond tend to hold more value due to their popularity in diamond jewellery.
