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.

A generous cluster of prong-set pear-shaped clear rhinestones tumbles across an openwork silver-tone setting, punctuated by small round marcasite-style accents at the edges. The shank is split and tapered, adding structure to what reads as an organic, scattered arrangement of stones. The dark oxidized tone of the metal deepens the contrast with the bright clear stones — a combination with roots in Art Deco jewelry that never fully goes out of style.

A bold floral cluster of round brilliant cubic zirconia — center stone ringed by eight larger stones, all framed by a pavé halo — sits atop a triple split shank set with additional CZ down each band. The layered construction gives the ring considerable presence without heaviness, and the rhodium-finish sterling catches light from every angle. Vintage-inspired in its cluster silhouette and generous scale, it works as well with denim as it does with a dressed-up look.
