#123 Compressed Magnesio-riebeckite

Alto Chapre, Bolivia

Fine compressed fibers of magnesio-riebeckite from Bolivia. This specimen is very slick, due to the immense pressure forced on the crystals, leading to fine micro-fibers. If you can understand that, you'll have proper respect for keeping it in a bag. 5.1 x 1.6 x 1 cm
