Jeremejevite

Jeremejevite is a rare and valuable mineral, sometimes used for jewellery making and also of interest to mineral collectors.

Jeremejevite crystals are typically blue or colourless, and have a hexagonal shape with pointed ends.

It was first discovered in the late 19th century in Siberia, and is named after the Russian mineralogist Pavel Jeremejev.

It is quite a rare mineral and larger pieces do tend to be rather expensive.
