What does this mean?

A Large Unmounted "Yellow Diamond"
the brilliant-cut stone stated to weigh 40ct, stated to measure 20mm x 19mm.

Judging by the photo it is Vivid Yellow

Valued on basis of being HPHT color treated but if found to be natural its value would be $3 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 HPHT treated vivid yellow diamond
