The Palelni mine is a beryllium-rich pegmatite area that has intruded into a peridotite body. The initial discovery was around 1993 and the production of gem quality material was sporadic. The main products are the locally called "mushroom" rubellite tourmalines. These fibrous tourmalines usually have a schorl seed and then a mushroom-like termination area more or less developed is possible. Another type of rubellite is present under botryoidal shape. These tourmalines are associated with quartz, K-feldspar, beryl (aquamarine and morganite) and also petalite, phenakite and hambergite.

Note: "mushroom" tourmalines also occur at the Kat Chay mine (see there).
