Ruby and black tourmaline crystal necklaceA flashy ruby is set at the top with an open eye, or sun on the back. Hanging below is a raw black tourmaline Crystal. The crystal is riveted in place, and also has expoxy sealing the setting and securing the stone so it stays stable in its setting without jiggle. The rivet is whats holding the crystal in place. pendant measures: 12mm x 52mm (1 2" x 2") This necklace does not come with a chain. I recommend this chain
