'Exporting' a few chips of rock internationally enforces capitalist values on matter that couldn't care less in awkward ways.

DE customs want invoices to prove what I've picked up from #MineWaste is worth (for a gift) so they can tax it.

The fact it's arsenopyrite is probably not an issue but […]

Dark spheres included in water clear quartz. Two have been split down the middle with red rings on shiny silver with dark red (almost purple) cores.

Not one of mine, but a photo I made of a friend's specimen - amazing spherical #Hematite ("kidney ore") inclusions in water clear quartz. Some of the metallic spheres are split, so you can see how they grew from a tiny dark red core. Found in #MineWaste at Botallack mine, #Cornwall.

A dark boxy crystal with hints of red on the right hand side from where I broke it a bit. It's attached to a matrix comprised of clear quartz.

Much shinier (aka 'gemmy') than the last one - this 4mm cubic #Cuprite is from #MineWaste at Wheal Unity Wood - a mile or two away from Wheal Unity. A lot of these #Cornish mine names and distinctions are famously confusing!

Two complex cuprite crystals, one on the right has a slightly more blue colour due to a coating of chrysocolla. Both on an orange 'limonite' matrix.

Recently I've been making better images of specimens I found previously - this is a pair of complex #Cuprite crystals from #MineWaste at Wheal Unity, Gwennap I found in a 20 minute visit in 2023 checking sites for #OrganisedAtoms workshops (I should check it […]

Squarish, tabular cerussite crystals scattered across an orange matrix with sections of exposed shiny galena showing typical right angled breakage planes.

Squarish, tablular #Cerussite on an orange matrix, surrounded by exposed #Galena with typical right angled breakage planes.

#Fossicked from #MineWaste at Wheal Clinton, Flushing, #Cornwall. Found below the high tide level, beneath the main shaft of an old […]
