Vtg Faceted Rock Quartz Crystal 925 Sterling Silver Stone Pendant Necklace

Vtg Faceted Rock Quartz Crystal 925 Sterling Silver Stone Pendant 17.25"-18.25" Necklace. Large Hook clasp. I believe this is turquoise, but I'm not sure how to test for turquoise. Pre-owned, this necklace is in excellent vintage condition.
