"There is no other consumer product that is more carefully graded than a diamond."

Diamonds can be described by using the 4Cs: cut, clarity, colour and carat.


A diamond's cut determines how much light is reflected internally from one facet to another, exploding through the top of the stone and giving the characteristic brilliance, fire and scintillation for which diamonds are renowned. The most captivating diamonds, that inspire our senses and famously addict us, are those that are cut to maximise light reflection. 

James Veale offers a range of cuts, in different shapes. Working with you and your budget, James will find the perfect stone to fulfil your ambitions.


A diamond's colour is measured by the degree to which the diamond approaches colourless. Colourless, or white, diamonds are rarer and more expensive than those with a hint of colour.  The  most colourless diamonds are graded D, E and F. The majority of diamonds are graded G - L. If a diamond is graded beyond M, you will notice a tint of colour. 

James Veale works with diamonds of Grade I or above, recognising the importance a crisp, colourless stone but also appreciating the subtle differences between the brightness of freshly laid snow and the calming shade of a white rose. 


A diamond's clarity is measured by how easy it is to see through it, based on blemishes on the surface and inclusions disrupting its internal integrity. Flawless diamonds, graded as FL, have the highest degree of clarity and command the highest prices. At slightly lower grades, inclusions will not interrupt the transparency of the stone to the naked eye, they are simply the diamond's individual fingerprint.

James Veale works with diamond of Si2 (slightly included 2) clarity and above. These grades are all uninterrupted by blemishes or inclusions to the naked eye.


A diamond's size is measured in carat weight. One carat is 0.2g. It is important to remember that whilst weight is important, two diamonds of equal weight can be of differing values depending on how well they are cut, their colour and their clarity. When all the 4Cs are at their best, a larger diamond will enhance all of the diamonds' delightful characteristics. 

James Veale works with a range of carat weights, and often uses different sized stones within the same ring to create maximum effect and outstanding charm.
