Mineralpedia Details for 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 Ray mine, Pinal Co., Arizona, United States
Unusual "balls", perhaps limonitic replacements of something which are totally covered by micro crystals of Cuprite to less than 0.2mm.
Cuprite from Carn Brea, Redruth, Cornwall, England
Deep red 1-2mm octahedral crystals all over matrix.
Cuprite from Ghostcroft mine, Mullion, Lizard Peninsula, Cornwall, England
A good representative specimen showing a solid vein of deep red Cuprite to 1.5cm in Chrysocalloa matrix with minor Malachite. The Ghostcroft mine is known for having the largest known specimen of Copper from England. It is said to be named for the flickering miners' candles seen at night by the locals. (Embrey). Though it was a source of copper it was sporadic.
Cuprite var. Chalcotrichite from Santa Rita, Chino mine, Grant Co., New Mexico, United States
Red acicular Chalcotrichite crystals to 1mm.
Cuprite from Bisbee, Cochise Co., Arizona, United States
Deep red Cuprite as scales and cubic crystals to 5mm.
Cuprite from Twin Buttes mine, Pima Co., Arizona, United States
Fine, fiery reddish orange, matted Cuprite, variety chalcotrichite covering much of all faces. U
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.
Cuprite from Tsumeb mine, Tsumeb, Namibia
Superb cherry red Cuprite crystals to 4mm and smaller on Calcite matrix with minor native Copper. Excellent matrix specimen.
CUPRITE from Wheal Phoenix, Linkinhorne, Liskeard dist., Cornwall, England
Deep red acicular crystals in bundles and patches to 4mm.
Cuprite on Kinoite from Christmas mine, Gila Co., Arizona, United States
This specimen has beautiful octahedral red Cuprite micro crystals to about 1mm sprinkled with good coverage on platy blue Kinoite. Excellent specimen.
Cuprite from Redruth, Cornwall, England
Octahedral crystals from 1 to 5mm.
Cuprite from Copper Queen mine, Bisbee, Cochise Co., Arizona, United States
Dark red micro Cuprite crystals throughout mass. Darker red than photos depict!
Cuprite from Black Pine mine, Philipsburg, Granite Co., Montana, United States
An interesting specimen with a lot going on. There is a large 2.5cm Tetrahedrite crystal coated with bright ren Cuprite. There is also brown acicular groups of Pyromorphite on the needle Quartz. And finally there are two Japan law twinned Quartz crystals, one of which is shown.
Cuprite from Morenci mine, Greenlee Co., Arizona, United States
Bright cherry red acicular chalcotrichite, a variety of Cuprite. The matrix is all Cuprite.
