This thumbnail piece consists of an aggregate of heavily intergrown Euclase crystals. These crystals are generally in only fair condition, as most of the exposed edges are damaged or broken. The largest has apparent dimensions of 0.3 x 0.3 x 0.2" (8 x 8 x 5 mm) Where visible, they appear to have good monoclinic prismatic form and the standard vitreous luster. Their color ranges from nearly colorless to a moderately deep blue with a hint of green. All appear to be at least dimly transparent, though internal fractions affect their clarity. Several small quartz crystals permeate this aggregate, but there is no real base or host material present.
