This Art Deco-period ring features not one, but two exceptionally rare Yogo sapphires. First discovered in the late 19th century in the Yogo Gulch in Montana, Yogo sapphires are considered among the world’s finest prized gemstones. These examples total approximately 0.75 carat and are joined by 1.10 total carats of white diamonds in their classic platinum Art Deco setting.
