When a member of our tour noticed that some of the sheets contained sprays of indicolite tourmaline, we all descended upon the mica heap like a swarm of locusts. |
Rubellite is the term used for red or pink tourmaline, and indicolite is the term used for blue tourmaline. |
Instead, a blue-green to blue tourmaline, some of which is considered to be indicolite, is now being mined in a different locality. |
Because of its rarity, indicolite from any locality is always in strong demand. |
