WILLEMITE , a See also:mineral consisting of See also:zinc orthosilicate, Zn2SiO4, crystallizing in the parallel-faced hemihedral class of the See also:rhombohedral See also:system. Crystals have the See also:form of hexagonal prisms terminated by rhombohedral planes: there are distinct cleavages parallel to the See also:prism-faces and to the See also:base. Granular and cleavage masses are of more See also:common occurrence. The See also:colour varies considerably, being colourless, See also:- WHITE

It has been found at only a few other localities, one of which is near See also:Liege, and for this See also:reason the mineral was named after See also:- WILLIAM
