What does this mean?

A Very Large Unmounted "Pink Diamond"
the brilliant-cut stone stated to weigh 100ct, stated to measure 31mm x 19mm.

Judging by the photo it is either Vivid Purplish/Pink

Valued on basis of being HPHT color treated but if found to be natural its value would be $60 million plus depending on clarity.

If it is in fact a natural diamond at all or treated HP/HT color, 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 treated HP/HT pink diamond
