A Large Unmounted "Orange Red Diamond"
the brilliant-cut stone stated to weigh 25ct, stated to measure 20mm x 19mm.
Judging by the photo it is Vivid Orangy/Red
Valued on basis of being HPHT color treated as these colours are not found naturally in such a very large size.
If it is in fact a color 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 orange/red HPHT diamond
