Vintage Platinum Old European Cut Diamond Signet Ring

This is such a good vintage signet. A solid platinum ring centered by an approx. 1.00 carat old European cut diamond, set low into an octagonal face with fine milgrain framing the stone. The broad shoulders taper into the band and give the ring a really clean geometric shape, while the old European cut throws broad flashes from every angle. Crafted in platinum and weighing 14.5 grams. The band measures approx. 8 mm at the widest point, tapering to approx. 4.5 mm. Center diamond is an approx. 1.00 carat old European cut, estimated H color / I1 clarity. Fits approx. US ring size 5.75–6.
