The importance of a GIA Certificate

Buying a diamond is likely to be one of the biggest purchases you ever make, so how can you trust an online retailer with your hard earned capital? It’s a fair question.

The Answer – Ensure you buy a diamond certified by the GIA at the very least. You can check the certificate here before buying, it’s free and well worth doing.

Who are the GIA?

The Gemmological Institute of America is a non-profit independent institute dedicated to research and education in the field of gemmology and the jewellery arts. When it was founded in 1931, GIA’s mission was to protect all buyers and sellers of gemstones by setting and maintaining the standards used to evaluate gemstone quality. By 1953 the GIA had developed its own International Diamond Grading System.

What is a GIA Certificate?

A GIA Certificate is a document, sometimes known as a diamond grading report, dossier, or a diamond analysis document that contains a full scientific and unbiased assessment of your diamond’s 4Cs. GIA tests every diamond submitted to establish its authenticity as a diamond and whether it’s been subjected to treatments. GIA reports provide a full description of the diamond, including colour, weight, measurements, and cutting style, and disclose any known treatments.

The GIA Certificate clearly sets out the Diamonds attributes in a way that makes it easy to compare and choose.

At London Diamonds we consider the Diamond Certificate to be the 5th C, as important to the value of your diamonds as Colour, Cut, Clarity and Carat Weight.

Unless you are very experienced in buying diamonds and feel confident evaluating the quality of a diamond yourself, buy certified. That way, you know the diamond you’re getting is graded correctly.
