Sapphire is corundum, the same mineral as ruby, and one of the hardest natural materials at 9 on the Mohs scale. Blue sapphire gets its colour from traces of iron and titanium. The pieces in this collection are rough, not cut gems: natural crystals with their barrel or hexagonal shape, usually opaque to translucent and greyish blue, as most rough corundum is.
Rough sapphire sells to collectors and to customers who want a September birthstone in its natural form. The weight-band crystals work well in specimen trays with a label, and the chips suit jars, kits and classroom sets. Because it is so hard, rough sapphire is also a good example for teaching the Mohs scale.
