Vintage 1980s Platinum South Sea Pearl & Marquise Diamond Ring — 15.5mm | 1.16ctw
Australian South Sea pearls at 15.5mm are among the rarest objects in fine jewelry — formed over years in the warm waters off the Australian coast, growing to a size that most cultured pearls never reach. This one is exceptional: white, smooth, and luminous with the deep, satiny luster that separates a great South Sea pearl from everything else.
Eight marquise-cut diamonds, totaling 1.16 carats of E/F VS/SI quality, crown the upper curve of the pearl in a tiara arrangement — architectural, precise, and entirely devoted to the stone they frame. The platinum setting completes the picture: cool, weighty, and built to last generations.
