Here is a "copper-based" specimen of bladed Chalcopyrite, Hematite, Malachite, and very gemmy green Fluorite. There are a BUNCH of photos of this crazy-cool specimen...

Before it was an Amethyst mine, the Humming Bird Mine was a Copper mine in the later 1890's. Here is a specimen of bladed Chalcopyrite in green Fluorite...

#Chalcopyrite is a copper iron sulfide mineral, with the chemical formula CuFeS₂. Because of its abundance and ease of extraction, chalcopyrite is the dominant ore for obtaining #copper. It's found in hydrothermal veins Read more:

Shiny, iridescent and striated #Chalcopyrite crystal cluster found deep inside a large mass of quartz, #Fossicked from #MineWaste at Wheal Clifford, Gwennap, #Cornwall

A golden crystal (more of a cluster of crystals perhaps) with striated faces and a variety of iridescent colours, greens purples and yellows. Clear quartz crystals around the edge.

A golden crystal with diagonal striations and a cleavage showing metallic interior, surrounded by clear quartz

We like to think this type of clean geometric minimalism is 'modern', but humans will have been influenced by these shapes since before we were human.

Cubes of #Galena #Fossicked from #MineWaste at East Wheal Maid. I found an approx 5cm thick section of druzy quartz vein, with lots of mineralisation present, which you can see here - plenty of #Chalcopyrite and #Sphalerate as well.
