What a cute collection of smoky quartz crystals from Switzerland (SmokyQuartzes.JPG, pg. 29). The idea of making collages of specimens is very cool and I wish they would do this in mineralogy textbooks to show differences in minerals and localities.

Hi Jamison,

You're right: Such collage arrangements sometimes can be good to show differences, that's why I got this idea when I wanted to show those Swiss crystals. But there ARE some mineralogical textbooks where these types of photos are used, at least in older books where this was the typical way to show specimens ...

Hi Tobi,

In general, I am not a fan of the spessartines from Loliondo, but I like your specimen a lot because of the sharp crystals placed aesthetically on matrix. Congratulations.
Michael

Thanks Michael, I also fell immediately in love with it :)

Quartz from Huanggang:

There are some kinds of hollow casts of a rhombohedral mineral (calcite, siderite, ankerite, dolomite?) at the backside of the specimen. I will take some detail photos during the next days, maybe one of you has an idea what it could be ...

What a nice group of pieces! You're learning very quickly, not only how to select new specimens but how to shoot them too. Congrats!

Tobi do you have any self-collected minerals you could also showcase? It seems that most of the specimens displayed are acquired.
