Moonstones are associated with moonbeams and moonlight and have long been cherished in antique rings and other jewelry. The luminescent oval cabochon cut moonstone that centerpieces this antique filigree ring is marbled with a bluish cast. The 18k white gold band of this Edwardian moonstone ring is elegantly carved in a lacy filigree pattern that lends an airy, light feeling. Circa 1910-1915.
