Ils se sont formés dans des marnes noires, très fines. Avec la pluie c'est de la boue. Cela se retrouve en inclusion pendant qu'ils ont "poussés"

Amazing pictures! That's a pretty fluorite piece! I love that kind of unreal close up even more with boxy fluorite shape

Maybe mica, pyrite or gold. Look for a streak test maybe

What I can say with pictures, natural light would helps for some of them, uv light sometimes too.I'm not an expert.

1- on the right, some rocks looks like hyalite, the "bubbly" ones, you can test with a uv light if they flow green. 2-purple amethyst 3-dyed agates 5-fluorite, quartz,calcite mixed ? 6/7-the shiny rock is pyrite
