Vintage 1930s .72 carat Old European Cut diamond engagement ring ✶ SALE ✶

A classic .72 carat Old European Cut 18K diamond solitaire ring. We acquired this Art Deco-Era stone loose and mounted it in a modern 18K yellow gold knife-edge band with a low-profile, platinum head. The best of old and new in one ring! The diamond has a nice wingspan and its steep crown facets, small (slightly off-center!) table, and open culet are perfection. We love the smooth, flickering, warm brilliance of this stone. Six tapered, platinum prongs hold it low and tight without taking away from the experience of its unique shape and personality.

Diamond details: (1) Old European Cut diamond, .72 carat VS1/I-J, Cut: Very Good (5.30-5.40/3.70mm)
