Gemmy spheres of grey-blue Willemite generously populate this plate, which itelf is coated by flashy white Dolomite. The Willemite spheres, which range up to about 8 mm, have a sparkly and silky surface, and where you can see the spheres in cross-section, the crystal surfaces have superb luster. The Willemite has a nice fluorescence, bluish and yellow, depending on the wavelength, and part of the white layer underneath has a brilliant cherry-red fluorescence. An excellent specimen.
