This is an emerald cut Green Tourmaline gemstone I purchased back in the late 90's at our local gem & mineral show - held here in Joshua Tree yearly for as long as I've lived here. I then had the gemstone prong set in a simple Sterling Silver setting. Unmarked. Size ~6.5 The emerald cut Tourmaline measures approximately 11mm x 8.5mm Excellent vintage condition - I do note one tiny nick to one of the facets, and there is some tarnish - I'll leave to buyer to clean. Please see all photos as these are part of the description and give the best idea of condition. Beautiful vintage ring for those who love Green Tourmaline! #vintage #90’s #tourmaline #gemstone #greed #emeraldcut #cocktailring #engagement #bridal #wedding #classic #elegant
