What does this mean?

A Large Unmounted " Diamond"
the brilliant-cut stone stated to weigh 45ct, stated to measure 26mm x 18mm.

Stated Quality
Color: D (Colourless)
Clarity: VVS1 (Very Very Slightly Included)

Valued on basis of being GIA certificated D VVS1 with graining

If it is in fact a natural diamond, once again it is impossible to sell without first obtaining a GIA gem diamond certificate to prove that it's natural and the quality as per the 4 C's.

Happy to review values once a GIA certificate is obtained.

Valuation is based on being a treat blue diamond
