"Vintage Gold, Platinum & Diamond Signet Ring"
Superb signet ring in 750/00 yellow gold (18 carats) and platinum whose four half-ovals, like corollas shouldered with diamonds, create wave effects with golden reflections and conceal a heart presenting a table diamond in closed setting. The body of the ring has been narrowed by the addition of an open body which can comfortably accommodate several finger sizes, from 56 to 60. French work circa 1940
