You can use any you can find on mineralexpert.org with photographer Zbyněk Buřival or Albert Russ, just reference authors, please.

There is an extensive gallery (~10k photos from many authors), but most good pictures are inside articles (well over 1000).

Hey guys, just a few ideas to improve:

1) Make the font a little larger
2) Add slightly more spacing between the lines
3) Break up the longer blocks of text
4) If possible, add some photos

This is hard to read.

Reach out if you need a help. Or photos - we do have a decent stock :)

IMA is not "recommending" but defining valid mineral names. I would say barite/baryte problem is minuscule compared to special chars in names like "kruťovite" or "škáchaite", driving all editors and database administrators crazy.
