We love this sparkling bracelet that catches the light with every movement for an elegant look. The Lock and Key Crystal Bolo Bracelet features a large round clear cubic zirconia crystal that sits in the center of the design, surrounded by smaller clear cubic zirconia crystals and silver tone. More clear cubic zirconia crystals are inset on the sides to complete the tennis bolo bracelet.Materials-Rhodium over brass. Cubic Zirconia. Rhodium over brass chain.
