Vintage Sterling Silver Multi-Gemstone Marcasite Ring

Five oval faceted stones — amethyst, peridot, champagne topaz, blue topaz, and amethyst — line up in a graduated spectrum across an oxidized sterling band framed above and below by rows of marcasite. Thai sterling workshops were producing some of the finest accessible gemstone jewelry from the 1970s onward, and the CNA maker's mark, wide tapered band, and oxidized finish suggest this piece dates to the earlier end of that tradition. Stamped 925, CNA, and Thailand on the inner band.
