Clear Quartz Crackle Point Blue Apatite Black Tourmaline (schorl) is anA polished crackle quartz point, roughly 1. 7 long. Clear quartz is pure crystalline silica. Crackle quartz is heated and then quickly cooled so a web of internal fractures opens inside the stone; those fractures catch and scatter light, giving the frosted, shattered ice look. The surface is then polished smooth. Quartz is Mohs 7 and durable. Each point is cut and polished by hand. One point per order. Natural stoneinternal fracturing and size vary
