Colour:
Copper red and silver ...
Lustre:
Metallic
Name:
Derived from "Half-breed", which is a derogatory American slang for a person whose parents are Caucasian and Native American. The general insolubility of silver and copper produces specimens containing intermixed white native silver and red native copper.
A physical mixture of native silver and native copper (they have only limited miscibility at low-moderate temperatures, unlike silver and gold; see electrum). The insolubility of copper and silver produces specimens containing good crystallized examples of both minerals, often in epitaxy. Copper on silver is more rare than silver on copper. Although such silver-copper nuggets are more common, many on the market are produced in stamp mills or ball mills.
