Diamond Guide

All of our Diamonds are chosen by us individually for the excellent properties they possess.
It is because all our Diamonds are hand-picked by our expert staff, that you know you are getting the best quality at the best price.

When we are choosing which Diamonds make it into our stock, we use the 'The Four C's': Cut, Colour, Clarity & Carat.
The following guide will help you to understand our Diamond selection process, and hopefully help you to make an informed decision when purchasing Diamonds yourself.

CUT Cut is a grading of how well a Diamond has been cut. A well cut Diamond reflects light back into the eye of the viewer, giving that famous sparkling brilliance. Cut too deep or too shallow and your Diamond will lose much of its potential sparkle.


Colour is graded on an Internationally recognised alphabet scale, from D to Z. Colour absorbs light as it passes through the stone, reducing Brilliance, so the less colour the better. D is the complete absence of colour, a perfectly white Diamond.

Diamonds that form naturally take billions of years, so it’s no surprise that they can come with a few imperfections. These can affect the passage of light through the stone. Clarity is determined by the number, visibility and size of these inclusions.

Carat is the unit of weight for Diamonds. 5 Carat is equal to 1 Gram. Larger Diamonds are very rare, which affects the price of a Diamond. A 2 Carat Diamond will not cost twice as much as a 1 Carat Diamond, it will likely be several times the price due to the scarcity of larger stones. *
