Like ripe berries full of juice these matte carnelian 12mm round beads from Dakota Stones are full of delicious red color. Available in 8-inch strands, these beads feature a smooth, round shape and matte red color with hints of orange. Carnelian is a translucent chalcedony or an A-grade agate that receives its beautiful red tints from iron oxides. Most deep red carnelian is heat treated to darken the material evenly; these have been tumbled to give them a matte finish. The ancient Greeks and Romans particularly valued Carnelian and believed that it could calm bad temper or still the blood. These beads are made from natural gemstones, so color may vary from bead to bead. Dakota Stones offers high-quality gemstones that are all useable in jewelry designs because every bead is checked to make sure they are cut and drilled correctly, that the finish is right and that the beads look distinct to their stone type.
