Smoky quartz, a new addition to my bestselling Bubble Necklace collection. Also called smoky topaz, this stone is a smoky brown color, with a mischievous sparkle and in an unusual faceted coin cut. I place this amazing gemstone between a rope chain. The bubble necklaces are always great to layer with other chains and the gemstone rests just perfectly against your chest. Smoky quartz measures approx. 8-10mm across. Choose 16" 18" or 20" long chain in your choice of sterling silver or 14k gold-filled.
