Stones

I'm in awe about Science as they discover a lot about different creations. Even different stones are even studied. Such stones are mostly the uncommon ones, and existed hundreds if not thousand years ago. Geologist probably took some time to find and study them.

It's amazing though, and probably such stones are expensive. Anyway it's nice to visit museums. You can learn a lot and that stones are also preserved and displayed with some bits of facts about them. Even the tools used by geologist are displayed. That way, it will be easy for us to learn how and what they are doing in finding and studying the stones.
