Variscite sterling silver necklace and chain. Matching sterling silver bracelet and sterling silver earrings. Variscite is a hydrated aluminum phosphate mineral. It is a relatively rare phosphate mineral. It is sometimes confused with turquoise; however, variscite is usually greener in color. The green color results from the presence of small amounts of trivalent chromium. Shipped with 20-inch chain unless otherwise requested. Chains available in 16-inch to 30-inch lengths. This variscite is from Nevada.
