The color is normally black, but also brownish black, orange, yellowish-orange and dark green as seen in the image.
AMR Minerals will bring Thorium samples for everyone to see at ThEC2010.
Ahmet, Director of AMR Minerals, says "Our thorium is unique as it is not in monazite but in a liberated form in thorite, hence without the need for cracking."
The crystalls range from a mear 40 micometers up to 1mm in size with a beautiful shade of green.
