A truly gorgeous piece, this vintage ring is by the German-born designer Claus Vollrath (hallmarked with his full name inside).

Vollrath got his start at Cartier, and eventually opened his own NY boutiques. He passed many years ago and much of his collection was sold at auction. This buttery 18k beauty is 5.75 (sizable) and deliciously solid at 7.8 grams. The bezel-set diamond in the center is .40 points and a sparklingly clear and white G-H/VS. A true heirloom piece!
