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.

Thank you, Carles! But it always depends on the specimens whether a photo is good or not, I know you often struggle with that, too. Specimens like the Peruvian rhodo and the Amatitlan amethyst are easy to shoot, I just took some photos and got these results. The spessartine from Tanzania, as you can see, has not the same photo quality as those two. And then there's another garnet specimen I wanted to show, a spessartine from Pakistan, but the photos were too bad, I'll try another day ...

Not most of them. ALL of them. I keep some minor specimens that I once collected, but none of them is good enough for my display collection. I once found some unusually large olivine crystals, here's a photo of my best find: https://www.mineral-forum.com/message-board/viewtopic.php?p=4809#4809

Tobi, self-collected specimens give a collection a different flavor or atmosphere in addition to self-collected specimens. While I agree that a good percentage of self-collected specimens are low-end, there can still be mid and high-end specimens found if enough effort or work is put in to finding them.
Don't hesitate to show those specimens as well. Germany has many localities and places where various specimens can be found. Germany is especially rich in Silver minerals (a favorite of mine) along with native elements.
On the subject of your recent additions, I like the Huangangliang Quartz. It reminds me of Dal'negorsk Quartz.

I just had to update my avatar according to my new standard of Peruvian rhodos ;-)

Sure, self-collected specimens always add something very personal to a collection. But I have limited space, there's only one display cabinet in our home and I have to make a good choice of about 130 specimens to be on display. As a friend of aesthetic classics from all around the world, my self-found "rocks" have no chance to be displayed, they have to be stored somewhere in boxes.
And you're also right that Germany has (or rather had) a lot of great collector minerals. But I don't have the time or the equipment to go on the hunt for the really good stuff - which is not much these days. My country has been a treasure chamber for many centuries, but mineral deposits are not endless and in the 21st century there are not many world-class localities that still produce good stuff. There are some really good German specimens in my collection, even from newer finds (mimetite from Badenweiler in Black Forest or galena from Meyer quarry in Eifel, if you know these localities), but I wouldn't have the opportunity to collect them by myself. However, I can even enjoy good minerals when they have been found by others.

This area is a gorgeous locality and no wonder that some call it "the new Dal'negorsk" ...

Thanks for answering my question Tobi. I wish I could come over to Germany and do some self-collecting myself. My favourite specimens from Germany are the radioactive and silver mineral specimens.
If you don't mind me asking do you have a special photographic environment built for photographing the specimens (ie light-box , point and shoot camera). The first pictures you posted were the specimens on a table with afternoon or noon hour sunlighting and then eventually moved to a diffused white background.
As for the Huangangliang Mine I see two similar species from Dalnegorsk specifically as Calcite ('Poker chip') and the 'ribbed' Quartz. Yaogangxian is also another possible 'Dalnegorsk' especially with very similar species and fame/notability.

I see we have different focuses on minerals, I never was interested in silver minerals or radioactive species. But with that focus, you should visit some museums in Saxony!!!

It's more than simple: I use a white paper background and natural light from above through a rooflight. But as I said before, it really depends on each specimen whether you get a good photo or not ...

Right!
There are photogenic and not photogenic specimens. Some pieces, no matter how long you spend trying to get a decent photo, are definitely not photogenic, and the task can often end with a nightmare. However, others can be successfully shot even by a 6-year old. The reason, I think, is that what your eyes see is quite different from what your camera sees.

Here's another new addition to my collection ... and sadly it is exactly one of those "problem childs" where you can try each and every light source and camera mode - and none of the photos looks good :-( However, I want to show that cute little garnet from Pakistan which looks actually better in person ...
| Mineral: | Spessartine |
| Locality: | | Shigar Valley, Shigar District, Gilgit-Baltistan (Northern Areas), Pakistan | |

Actually the photo is not bad. Very well defined edges, and the faces hue is clearly distinctive. The near white matrix against a white background might be the only defect but after all the most interesting area is the garnet crystal, so the matrix doesn't matter at all.

There are parts that either appear to be soft or out of focus and you can see the presence of noise/film-grain on the actual Spessartine. Could also be due to the white on white conflict.
The Garnet has an interesting appearance but I personally prefer those from Fujian Province and their associated minerals. It's still a nice example with good form and condition.

I also love those from Fujian: https://www.mindat.org/user-5297.html#2_0_0_0_0_0_wushan
