Denim lapis beads provide a more economical, lighter blue variety of lapis lazuli beads. Like other lapis, denim lapis contains grains of several blue minerals, including lazurite and sodalite, plus a matrix that includes speckles of pyrite. The lighter color of denim lapis comes from a higher concentration of calcite inclusions in the gemstone. The light inclusions lower the value these semiprecious beads, but also make denim lapis a great accessory for casual, blue-jean outfits! As with lapis lazuli, denim lapis is believed to be a stone of spritiuality, truth, and friendship. These beads are easily scratched and chipped, so make sure to clean them only with a soft, dry cloth.
