Corundum crystal sets

Corundum crystal sets

Sets of four Corundum crystals, including small pieces of black, pink/red, pink/purple, and blue Corundum.

The pieces are typically around 10-15MM wide.

The black Corundum is a synthetic material (Emery), the rest are natural specimens.

The pink/red piece is from Ketito, Tanzania, and the blue and pink/purple pieces are from Madagascar. The pink/red and pink/purple crystals are UV fluorescent.

I've shown the pieces mounted to a black plastic stand as a demonstration, however, these will come unmounted without a stand.

Hopefully in future I'll find some reasonably priced but good quality display boxes; the plastic ones unfortunately scratch very easily.
