Ruby – Natural, Faceted, Purple, 1 ct

This is a beautiful antique ring, but the ruby and diamonds have received native cuts. While these cuts retain much of the mass of the rough stones, the resulting gems have irregular shapes and don't look very lively. 18k yellow gold, 1-ct ruby, and 0.15 ctw diamonds.
