Carat Size:0.5
Cut:FANCY CUT
'Fancy' diamonds (anything non-round) are not given a cut grading by the GIA, because there are too many variables to calculate within these different shapes. Therefore Kensington hand-select only pear, oval, cushion, emerald, princess, radiant, asscher and marquise diamonds which have internal cut proportions we would classify as 'Excellent'. Any diamond not living up to our expectations of maximum brilliance and sparkle will be discarded.
Color:E
Extremely colorless diamonds; often indistinguishable from the highest grade D Color.
Clarity:VVS1
An extremely high quality diamond, with inclusions so tiny they are very difficult for trained professionals to see under 30x magnification. Impossible to see with the naked eye.

They are recognised as the strictest graders of diamonds in the industry, giving you the peace of mind that you are always getting exactly what you paid for.
