Cuprite

Cuprite

Named from the Latin word for “copper,” cuprum, in reference to the mineral’s copper content. Cuprite is a common mineral that occurs widespread and in many localities worldwide. Fine specimens can be found from localities in Russia, Kazakhstan, England, Germany, Namibia, the Democratic Republic of the Congo, the United States, Chile, Mexico, and Australia. Cuprite occurs commonly in oxidized copper deposits.

CUPRITE from Gwennap, Cornwall, England

CUPRITE
            from Gwennap, Cornwall, England

Deep red cubo-octahedral crystals of Cuprite to 2mm. As always in digital photography, the red in the Cuprite is always accentuated, which is not intentional on our part. It just happens. In other words, the red is darker in person, but the crystals are superb. See old Lythe label under provenance.
