When it comes to diamonds, jewellery newbies as well as aficionados need to keep the  4Cs in mind – CARAT, CLARITY, COLOUR and CUT. On this blog entry, we will concentrate and discuss colour.

According to the Gemmological Association of Great Britain (Gem-A), a globally established name in gem and jewellery education, these elements are pivotal when it comes to pointing out subtle or otherwise noticeable in diamonds. It should come first before deciding on setting them in gold, silver, or platinum jewellery.

They also said that, “colour intensity – the deepness or richness of colour, is the most important consideration when purchasing a coloured diamond.

There is a grading system for diamond colours  as well. It ranges from D to ZD being the assigned value to diamonds which are extremely white and rare; and, Z for diamonds which have unwanted hues in them.

Let us walk you through the grades a little further. The diamonds which are rated D, E, and F are all colorless. On the other hand, the stones which were graded G, H, I, and J are nearly colorless.


Diamonds of grade K, L, and M have some color to them – a diminutive hint of yellow, to be exact.

Diamonds graded N, O, P, Q, and R have a stronger tinge of yellow tints in them while grades S through Z graded diamonds are visibly tainted and, unfortunately, highly visible to the naked eye.


The diamonds that fall into this bracket may even take on a brown appearance. They, too, take on a much different shade once they are mounted on particular precious metals.


Getting well-acquainted with the grades will help both jewellery newbies and gem aficionados gauge a diamond’s truest worth.

We strongly advise that you ask your jeweller for a Certificate of Authenticity before you purchase loose diamonds and those which are already set in ready-to-wear jewellery.


Also, it is just as important to keep in touch with a diamond expert. Call House of Diamonds London or send an email to receive more information about these precious stones.
