Ekanite is green to brown colored rare stone with chemical composition calcium thorium silicate.
Thorium is a highly radio active element and due to this element Ekanite is converted to metamict state. In metamict state Ekanite almost acts like amorphous. By applying heat at certain temperature the metamict state of Ekanite can be restored to crystalline state.
The main source for Ekanite is Sri Lanka and Canada.
