Diamond shapes | About Diamonds | The 4 C’s | Diamond Sizes | Coloured Diamonds

1.  Diamond Carat Weight (choose from the drop-down)

This determines the size of the diamond (see our diamond sizes for approx dimensions) and is usually set by budget.

***PLEASE NOTE - WE DO NOT SELL CLUSTER DIAMOND RINGS OR 'ILLUSION' SET RINGS AS COMMONLY FOUND ON THE HIGH STREET - ALL OUR DIAMOND ENGAGEMENT RINGS ARE SET WITH A SINGLE LARGE DIAMOND IN THE CENTRE RATHER THAN A CLUSTER OF SMALLER, CHEAPER DIAMONDS***

2.  Diamond Colour (choose from the drop-down)

Other than size this can be most obvious diamond characterist noticeable to the naked and untrained eye.

3.  Diamond Clarity (choose from the drop-down)

Diamonds need to be studied close up or by using a jeweller's loupe to notice any inclusions in the diamonds we sell as we do not offer 'PK' diamonds with very noticeable inclusions to the naked eye.  

4.  Cut

We only sell diamonds with a minimum of 'Good' cut.

DIAMONDS SOLD IN HIGH STREET JEWELLERY CHAINS ARE NOT PICKED FOR THEIR COLOUR OR CLARITY, THEY USE LOW GRADE DIAMONDS OF POOR QUALITY - PLEASE ENSURE YOU PRICE CHECK 'LIKE-FOR-LIKE'

The 4 C's of Diamonds

The 4 Cs will help you when choosing diamond jewellery, especially if you are buying a diamond engagement ring.  It is the combination of these characteristics which determine the value, rarity and beauty of your diamond.  These pages are here for your guidance as it can seem a little confusing when purchasing diamonds however, we only sell white diamonds without inclusions visible to the naked eye and with a minimum of good cut, polish and symmetry. 

Diamond Colour

Whilst most diamonds appear colourless, many actually contain subtle shades of yellow or brown. The closer a diamond is to having no colour, the more valuable it becomes.  Diamonds with a ‘D’ colour grade have the least colour with the scale going all the way to ‘Z’ which means the diamond will have a light yellow colour.

We offer diamonds on the scale from ‘D’ to ‘I’ all of which are considered white in colour but have very subtle differences which can take years of experience and training to appreciate.

Diamond Clarity


This refers to the inclusions a diamond may have.  An inclusion is a naturally occurring mineral or fracture within the diamond.  These are usually invisible to the naked eye and the fewer inclusions in the diamond, the greater the clarity and the more value it has.

Diamond Carat


A diamond's carat is a measure of its weight, not its size. Larger carat weights are rare and valuable. However, two diamonds with the same carat weight can have very different values depending on their colour, clarity and cut.

Diamond Cut


Cut refers to the angles and proportions created when transforming a rough diamond into a polished diamond ready to be set in a piece of jewellery. Cut is the only one of the 4C’s that is not naturally created when the diamond is in the earth as they are cut by skilled craftsmen to bring out the very best in a diamond. The skill lies not just in cutting the diamond itself, but also in the proportion, relationship and angles of each of the surfaces, known as facets. The tiny facets are then polished to create the table, crown, girdle, pavilion and culet.
