For those who want something a little different, something a little wilder, yet still sophisticated, this ring may be the one. Pink Tourmaline and iridescent gen quality Ammolite set in sterling silver. Combined with little gold accents and a Baroque band, this is very much a one of a kind piece. Ammolite is a rare, iridescent, gem-quality material cut from the fossilized shells of extinct sea creatures known as ammonites. Found only in the Bearpaw Formation in Alberta, Canada, this organic gemstone has a dazzling range of colors and patterns and is highly desired for freeform natural cabochons.
