150CTS CLEAR CRACKLED QUARTZ CUBES APPROX 6MM
Quartz is a hard, crystalline mineral composed of silica (silicon dioxide). Crackled quartz has been intentionally fractured usually by heating rock crystal or slightly translucent quartz to a high temperature, then suddenly quench it in cold water. The shock of sudden cooling causes a network of tiny fractures to propagate through the quartz.
Approximately 65 beads.
