Mineral Specimen #5027 Malachite on Quartz with Casts after Calcite, Minor Chalcopyrite
Mina El Cobre, Zacatecas, Mexico
Ex. Robert Gannon
White colored Quartz with a vug containing very nice, bright green colored, needle like crystals of Malachite. These crystals have a high, sparkly, attractive luster. The rest of the vug is coated with iron oxides. There are casts in the Quartz on one side and on the bottom of the specimen. These appear to be after Calcite.
Condition: Very Good
Flaws: The Quartz is broken surronding the vug, but the interior of the vug is in excellent condition with no damage.
