Description

Quartz covering chrysocolla pseudomorphed after malachite pseudomorphed after azurite (most likely). This specimen also has a minor dusting of tenorite and malachite on the surface of the quartz. It is unconfirmed whether the very initial crystals these specimens were were either azurite, baryte, or gypsum, though chemistry leads most to believe azurite.
