United States (c1970) An interesting gold, lapis lazuli, malachite, tigers eye and diamond ring. The 3/4 x 5/8" 18k yellow gold square shank with white-gold topped diamond cutaway frame (approximately 1.00ct) in which a hinged cube is mounted. The modular designed cube displays four sides: lapis,malachite, tigerseye and pave diamond (approximately .25cts). We love jewels that do tricks! This four in one ring is great for travel and without a doubt goes with everything. Chic and Savvy. Signed T.L.I.Size 6.75
