Synthetic Sapphire / Corundum boules (Clear)

Synthetic Sapphire / Corundum half boules (Clear)

Half fractured boules of synthetic Sapphire/Corundum. These are lab grown and typically clear to cloudy white.

These are ideal for faceting practice, although in some cases they are slightly cloudy or have some cracks or fractures from where the boules were split in half.

Currently I am charging around 25p per gram for these; I think this is about the lowest price available in the UK.
