I like it very much

Nice specimen!

Very nice amethyst, Carles. Smartphones are pretty smart indeed.

To Tobi, Nunzio and Don:

I'm very glad you like it. Thanks for your comments! It looks like the long hours spent on taking and processing such a large number of photographs were worth it. And it was even a little fun.

A very fine spray of hübnerite in an impressive (!) size, really a great specimen. I know your taste in aesthetic minerals and your love for Peruvian specimens, and I think this specimen is the logical consequence of these two factors :-)

[quote="Carles Millan'']The crystals are fully transparent but unfortunately my camera doesn't know how to do the job. Or it's me? [/quote]

Hi Carles. I have a few similar, very clear, quartz specimens. I find these the hardest to photograph and then they hardly ever look close to the real thing:-(

I forgot. Sorry!

The human visible spectrum includes wavelengths from about 390 nm to 700 nm. We cannot see light from below and above such range (which would be UV and IR light respectively). Other animal species can see slightly different wavelengths. But the range that the cameras see must be even more different. Not to mention the big difference of resolutions. So it's no surprise that the photos we get don't match the images we directly see.
