Hand hammered sterling silver disc has a bright blue topaz stone, surrounded by a 14k gold bezel (the part that holds the stone in). The bale is large enough to fit your necklace (not included). The texture of the disc and bezel catch the light. This would be fantastic with a simple white tee shirt and jeans, or a small bit of glimmer to your work suit. 
(This can be custom made with any color stone.)
