C. 1970’s Joachim S'Paliu hollow ring with onyx inlay in sterling silver. This ring has perfect curved edges and a luscious and bubbly dome on top. The top of the ring is hollow, making it ergonomic and comfortable despite its height. The smooth inlay creates a fun optical effect as it gets smaller down the sides of the ring. Purity and artist hallmarks stamped on the inside of the ring. 

Size 7.5, resizable. 9.85 grams
