If you research buying diamonds or diamond jewellery you will certainly come across the expression “The 4 C’s”. These are Cut, Colour, Carat, Clarity. Whilst these four measures are a very good start when evaluating a diamond there are more things to consider. Another “C” of course is cost so we’d better add that one now to make 5 C’s because no matter who you are you’ll have some sort of budget for your purchase. So let’s break each of the C’s down…
CUT: This is more than just the shape, you need to look for the quality of the cut. If the cut is poor there will be shadows created in the stone. Move it around to see if you can see any.
COLOUR: Ideally we all want a diamond as clear and colourless as water. Basically the less colour in the stone the higher the price (with the exception of fancy colours).
CARAT: In most cases the higher the carat weight, the greater the per carat price of the diamond. A carat is 1/5 of a gram.
CLARITY: The fewer, smaller and less noticeable the flaws, the higher the diamond price. Look at the stone with a 10x magnifier to see any flaws, usually black carbon fragments. Don’t make the mistake of just looking at the centre of the stone, the flaws may be around the edges.
COST: Your final choice will of course take cost into account.
