Like twinkles of light from stars surrounded by inky darkness, the onyx 6mm faceted roundels from Dakota Stones display black color interspersed with twinkling shine. Available in 8-inch strands, these rounded beads feature a glossy black color that is only enhanced by the small diamond-shaped facets that cover their surface. Onyx is a variety of chalcedony that is similar to agate, with straight rather than curved bands. Nearly all black onyx on the market has been rendered a uniform, permanent black color with a treatment by sugar and acid or heat. This process has been used on onyx for thousands of years and does not decrease the value of the stone. Mined in Brazil, India and Madagascar, onyx is said to signify a happy life with a suitable companion when you dream about the gemstone. Dakota Stones offers high-quality gemstones that are all useable in jewelry designs because every bead is checked to ensure they are cut and drilled correctly, that the finish is right and that the beads look distinct to their stone type.
