What a beautiful stone!

Why do you think we love diamonds so much when there are other, more beautiful and unique shapes out there?

The Forest of Pillars in Egypt’s Sinai Desert. Many believe the tubes were formed by lava, however it seems more likely to be ancient hydrothermal vents.

Dr. Bonnie Sampsell states: 

“The rocks are composed of hematite (a form of iron oxide). The iron oxide was dissolved out of the sandstone bedrock, to which it imparts a reddish colour, by hot water emerging from deep in the earth. As the water reached the surface and cooled, the iron oxide precipitated in a ring around each source, forming a tube.”

Some pure titanium, and the TiO2 (“titanium rust”) is such a nice color. Also if you kinda squint it looks like a T-Rex is formed by the blue.

A trippy chunk of malachite. Just look at those whorls!

Minerals are really awesome. This example of stibnite is both awesome and beautiful!
