Iowaite on Muscovite

Item Description

Excellent specimen of lustrous, gemmy Muscovite richly coated with attractive and undamaged groups of hexagonal, tabular, brownish bronze Iowaite. In fact, the Iowaite, which averages about 2 mm each crystal, is translucent to gemmy, especially along the edges. There, they glow a beautiful golden amber, and their luster is very good. A fine example of a quite rare oxide. Old piece, from the early 1990s
