What does 'carat weight' mean?

17 Mar 2019
Carat weights and sizes

'Carat Weight' refers to the weight of a diamond/gemstone.

Of the '4 C's', carat weight affects the value of a diamond more than any other factor. 

We try to display the carat weight as well as the size of the stone in millimetres on our product pages for your reference.  You should find this in the Item Specification/Description when customising a ring.  If this isn't shown for the item you are interested in, please contact us and we can provide this for you.

We have prepared below a diamond size/carat weight chart below for your reference. The chart shows 'carat weight to millimetres' which can vary depending on diamond shape.  Please note all sizes are approximate and the imagery used is just a guide, it's not to scale.
