I have used a multitude of sterling silver beads with a key pendant of blue quartz in the shape of a chakra that has a 925 bail. The necklace chain is sterling silver beadalon wire with the sterling silver beads on top. All the findings are sterling silver and the necklace comes with its own presentation box. The necklace measures approx 16 1/2 long with an additional 2 inch heart extender.
