Offered for sale on this page are cabochons of a variable mixture of Azurite and Malachite from Yukon. Both malachite and azurite are copper-bearing minerals than form when other copper minerals (usually copper sulphide minerals) breakdown during surface weathering processes. Copper was mined from the Whitehorse copper district between about 1900 and 1982. The material from which these cabochons were cut was recovered during reclaimation activities on the Pueblo Mine in Whitehorse, Yukon.

This azurite and malchite-bearing material is quite porous in places and like many other opaque gem materials, it required stabilization with expoxy resin before they are cut and polished.
