Black tigers eye is produced by heating the yellow and brown variety of the mineral tigers eye.
This beautifully polished stone is incredibly chatoyant. Chatoyance is an optical phenomenon that's caused as light reflects off the fibres within the stone.
As this piece is gently moved back and forth, even with minimal lighting, chatoyance can be seen.
This gem-grade black tigers eye stone is fully polished. It could be mounted into a piece of jewellery or be enjoyed as part of a collection of rough or polished rocks and minerals.
