Estate sz7 TIFFANY &Co 6.3mm GIA DIAMOND 850PT* solitaire 4prong engagement ring

Genuine Tiffany&xo Vintage so some of the markings are a little faded inside the band 4 prong Sz7 A 6.3mm round cut genuine diamond (@1ct) Very high quality and clarity as Tiffany only takes the 4 highest grades and clarity diamonds. Tiffany & co please return to laser engraved on surface of stone Laser engraved in stone is plat*900 as well as the serial number for the diamond, which is gia certified. I do not have papers on this or any authentication except for magnifying the etchings in the stone :) Very comfortable setting! Very durable and hard metal! Platinum actually displaces gold rather than losing it, so the ring maintains its shape and size through the years no matter how many times it’s scratched or tested for purity Passes as platinum & 22k Serial number is written on prong for ring as well As a serial number that looks like it is inside the band These are not cheap. This is a very sought after ring ! I feel my price is fair, if you’d like to make a very reasonable offer I’ll consider but a lowball will get blocked! Thanks! Check my page for more!
