Make bold designs with the help of the smoky quartz faceted hexagon beads from Dakota Stones. Available by the strand, these gemstone beads feature hexagonal shapes with large faceting around the edges. These beads are large in size, so make excellent focals in necklace designs. Smoky quartz is named after its smoky color, which is caused by gamma rays. The color of smoky quartz ranges from brown to black and sometimes smoky gray. Mined in Brazil, the stone is believed to enhance organizational skills, making it good to have around the workplace or home office.
