Circa 1970s, 18k, by Gubelin, Switzerland. Modernism ruled the mid-century fashion world and this tasteful bracelet from Gubelin is a stellar example. The Andrew Grima-inspired design has never gone out of production, (every few years Gubelin produces a few pieces). (Ours was made in the 1970s.) Casual enough for heels and jeans, it has an artistic authority that makes it a great match for cocktails or ball gowns. Excellent condition.
