I finally found my rock collection for this episode!

This is honestly the less interesting lot in my opinion. On the left we have lapis lazuli with a bit of quartz and pyrite in there, alongside turquoise and cloudy quartz. The black three on the right are jet or in one case, hematite, but the camera didn't catch how reflective it is very well.

And of course an ammonite fossil with a bit of quartz in the chambers.
