Though this thumbnail piece looks just like a nondescript chunk of pegmatite, that also describes the appearance of Amblygonite. What appears to be albite on this piece is actually Amblygonite, with a creamy-white color and a pearly to greasy luster. It shows no actual crystal form, but there are several visible cleavage planes. It is, of course, opaque and is accompanied by milky quartz.

Dims:1.5x1.3x1.2" (3.8x3.3x3.0 cm)

This is a single large partial crystal of amblygonite. The back side of this specimen is included with muscovite mica. The top and bottom of this specimen are bounded by cleavage faces, while the back and one side are fracture faces. The crystal is a light honey color, and is nearly transparent. Other than the damage already mentioned, this is an excellent specimen of this lithium mineral.
