This miniature has balance and contrast, for hosting a significant, fat, euhedral copper crystal on the contrasting white matrix. Massive white quartz is the host for a single, bronze colored crystal of copper, measuring 3.2 cm across. The robust red-brown coloring of the copper crystal appears to be caused by a thin film of tenorite, as is typical for the location. Superb old USA classics, and affordable in miniature size.
