Wonderful specimens and superb photos, your collection seems to be assembled with knowledge, passion and a keen eye. I see a mixture of rare minerals and great classics, simply beautiful.
The mimetite from Saxony is a stunner, one of Germany's most desired classics in fine quality.
Please more :)

An outstanding collection of little treasures and rarities, really impressive!
As a collector of common stuff like quartz, fluorite, tourmaline or rhodochrosite I must confess I didn't even know all of the minerals you posted. Magnesiokoritnigite, magnesiocanutite, dingdaohengite, preobrazhenskite, wakabayashilite, I never heard those names before (as a collector who is in the business for 30 years!). I feel like a mineral philistine ;-) But this makes your postings very educational, thank you and please share a lot more of your treasures here!
But besides these (for me) completely unknown things: Congratulations on that beautiful gemmy phosphophyllite - a kind of "Holy Grail" in the mineral collecting world!
Best regards
Tobi

Thanks, everyone!
Yes, it took a while to obtain a decent phosphophyllite specimen. They are around, but unfortunately the hype around these priced them out of reach for average collectors (like so many things today..). So I was happy to get this one out of an old collection :)

| Sun Yi, Your phosphophyllite twin is amazing, and very unusual with that pyrite perched on it! I lived in Bolivia for 12 years and saw many phosphophyllites, occasionally with pyrite on the matrix, but yours is unique with that pyrite on top!

True words! I'm glad that phosphophyllite is not on my wish-list, it would be frustrating. I'm really happy for you that you could find one. And not just one but a really outstanding one! Like Alfredo said:

Alfredo knows what he's talking about and you won't get a better praise for this piece. So instead of "just" a Holy Grail you rather found the Holy Grail among the Holy Grails ;-)
