The enigmatic black color of the onyx 10mm round beads from Dakota Stones looks like it goes on forever. These classic round beads feature a glossy black color that has great depth to it. Onyx is a variety of chalcedony that is similar to agate, with straight rather than curved bands. It has a Mohs hardness of 6-7. Metaphysical Properties: Often known as a protection stone, onyx absorbs and dissolves negative energy from the body.

Because gemstones are natural materials, appearances may vary from bead to bead. All Onyx beads are heat-treated. Dakota Stones cuts its Onyx from rough material that is heated at least 3 times to make sure the black color is consistent and any light lines are not visible. Each strand includes approximately 20 beads.
