Cut of a diamond

'Cut' is considered to be the most important characteristic of a diamond. It refers to the angles and proportions created when a rough diamond is transformed by a diamond cutter into its final polished state.

The cut grade is a measure of how well light is reflected within a diamond, and is what will produce what we call 'sparkle'.

When a diamond is cut well, light is returned out of the top of the stone, whereas if it is cut poorly, light leaks out the bottom of the stone producing less 'sparkle'.

We use 'Very Good' cut graded round diamonds as standard.  The untrained eye will often not detect the difference between a Very Good or an Excellent cut stone.   Diamonds with a cut grade of Good or Very Good, represent an excellent combination of value and sparkle, particularly Very Good cut diamonds which reflect nearly as much light as an Excellent cut stone but for a lower price.

If you'd like a price for an Excellent cut stone, please email us the item details including carat, colour and clarity and we will provide a quote - sales@purelydiamonds.co.uk

Be wary of companies who sell cut grades such as “Super Ideal,” “Signature Ideal,” and others. These 'branded' cut grades are not part of the internationally recognised GIA grading standard, which only uses Excellent, Very Good, Good, Fair and Poor.
