Raw Amethyst Silver Ring, Openwork Arches is a piece that is intriguing and pleasing from every angle. Featuring a deeply colored raw gemstone, in this case a majestic purple amethyst weighing approximately 5.01ct, the stone is held in by prongs and arches of metal that come up around the sides of the stone. Underneath the seat of the gem there are open sections allowing skin to show through the silver. Cast in sterling and set/finished in our Northern Michigan store this design is new in our case as of 2016, designed by Julie Terwilliger. This ring weighs 7.89 grams. Raw/rough Gems: Due to their fragile nature and delicate crystal structure, any unpolished/un-faceted gem cannot be warrantied. As a novelty item, raw/rough gems are not recommended for everyday wear. Wear at your own risk.
