Vintage sz8 Plat*22k tested 7mm Diamond high mount ring 5g weight

Please read all before buying Size 8 Vintage custom ring Comfortable flat base Marked 800 or 900 (hard to see) & 18k Solid Platinum Weight 5.01g Was sized, and whomever resold this stamped it 925 Thai and HAN but that is NOT a proper marking and can be removed by a jeweler. Original markings are underneath setting and on inside of band, just faded due to sizing. Serial number for ring is present as well. I believe this is a custom piece The 7mm center diamond appears to be a van cleef & arpel diamond Makers marks on the prongs are VCA However, this could be a diamond with a different brand base Can’t be 100% on the brand Selling as is Passes as platinum & 22k. Fails 18k *FAILs for 925 sterling* just to double down on the improper marking. Whoever has a stamper quit stamping stuff nimbly bimbly like a fool. Smh This is a very dense hard metal, it displaces gold when scratched on the acid test board, rather than rub off so overtime it maintains its original size and shine, so if you go to test it at home, just note it takes a hard scratching to get a good test line Split shank with pave diamonds Uv light glows a beautiful blue/pink which is common with higher end diamonds Diamond has serial number on inside accents have clarity next to bottom on inside of band If it’s a lab Diamond, I cannot tell I am not a gemologist but I can see natural inclusions in the stone, seen in magnified photos. You decide! Selling as is Priced accordingly I ship daily
