Hello!
To your knowledge, which are the rarest minerals on Earth that are actually beautifully crystallized (not microscopic granules or some powdery stuff on a rock)? Many thanks!

| How about andyrobertsite? Beautiful blue crystal, and only one specimen in existence, plus a few tiny crumbs for the systematic rare species collectors that were broken off of the one big piece.

It is normal to credit other people's images when we publish them. In this case the photo of this fabulous Wittichenite should be credited as follows:
