MonoMonday - Rock

This is one of these very inconsiderable rocks called "Druse".
Inside you find a glimmering wonder: a hole filled with different crystals.

I think sometimes people are equivalent:
You never know what sits inside a person :-D
(But I don't say: Slice them to have a look :-P)

Thank you nickimags888 for hosting MonoMonday this month :-D
