Rock, mineral, fossil collections

I've recently started investigating UV fluorescence in my specimens.
Here's my Cornish autunite (or meta-autunite).

   

some Cornish green fluorite

   

and some Cornish opal.

I've recently started investigating UV fluorescence in my specimens.

I rediscovered my collection 3 times. First with 365nm, then 250nm, and 2 months ago with 310nm 😅

Cornish

Cornwall has quite a mineral list! https://www.mindat.org/loc-840.html

Have you got cornwallite, BTW?

I don't but I can offer you luxullianite, a tourmalinised granite also unique to Cornwall (so far as I know).
Pink orthoclase, black tourmaline.

Thank you! Actually, I was curious about your collection of Cornish minerals, because cornwallite is named after Cornwall and its type locality is Cornwall. So, I think, you should get it 😉 And it looks great!

Yep, luxullianite (as you said, a type granite, not a mineral) is named after Luxulyan from Cornwall. https://www.mindat.org/min-50413.html
Oh, BTW, it should be purplish under a strong 365nm!

Personally, my collection is based on the rocks I like (at the moment when I see them). No particular system. Or, for example, I bought alfredopetrovite from Alfredo Petrov (not because I collect stuff from El Dragón mine or because alfredopetrovite looks particularly stunning 😉 ). I'm not sure I would buy it from anybody else 😉

I haven't actively collected minerals for over forty years! I'm all fossils nowadays 😊
