A classic and rare old-time Cornwall combination specimen consisting of Copper, Cuprite and Quartz. This piece is essentially a solid combination of metallic, reddish brown Native Copper and dark red Cuprite crystals with some scattered white, stubby Quartz crystals poking through for added contrast. The piece is essentially half Copper and half Cuprite with the Copper as jagged, subhedral crystals admixed with fairly well-formed Cuprite crystals to 4 mm. There is even a minor amount of light lime green Conichalcite in one area. Cornwall is one of the founding sites of the Industrial Revolution that shaped our world, and was productive of many ores including Copper, but so few specimens have survived to the present time among what came out in the heyday. Among those underpopulated in the survivors is Native Copper, both because it was processed found, and because it was oddly rare in specimen form in Cornwall to begin with. Whereas mining districts like Michigan have mostly Copper and Silver and few secondary minerals, Cornwall is much more famous for its secondary minerals. For the collector, this makes Cornish Copper specimens a paradox because they are less common than the rare Copper secondaries from here. This piece assuredly dates to the 1800s or before. NOTE: this has a very special and unique style of Copper, combined with Quartz. After internet research, although it was simply labelled as Cornwall, we have decided to attribute this to a mine showing such distinct style (as opposed to more commonly seen copper usually from the Relistian Mine): Marke Valley Mine, Upton Cross, Linkinhorne, Cornwall, England, UK.
