Ekanite

Silicate mineral

Ekanite is an uncommon silicate mineral with chemical formula Ca 2ThSi 8O 20 or (Ca,Fe,Pb) 2(Th,U)Si 8O 20. It is a member of the steacyite group. It is among the few gemstones. Most ekanite is mined in Sri Lanka , although deposits also occur in Russia. Clear and well-colored stones are rare as the radioactivity tends to degrade the crystal matrix over time in a process known as metamictization.

The type locality , Ratnapura District , Sabaragamuwa Province where it was first described in 1955 by F. L. D. Ekanayake, a Sri Lankan scientist,

In Sri Lanka the mineral specimens occur as detrital pebbles. In the Tombstone Mountains , Canada, the mineral is found in a syenitic boulder. of Italy
