Red Beryl Crystal Cluster: This cluster of crystals is one of the finest examples of red beryl in the world. It is a small specimen (all specimens of red beryl are small), measuring 6 x 2.7 x 2.6 centimeters in size. It was collected from the Harris Claim in the Wah Wah Mountains ...

Fire obsidian is formed when lava cools very rapidly, preventing the formation of crystals. This results in a glassy material that is highly reflective. The magnetite layers within the fire obsidian cause light to be reflected in different ways, creating the iridescent colors and patterns. ...
Instead, the rock masses collided at a velocity of a few centimeters per year. The collision and crustal compression would require millions of years to complete. The high temperatures and shear stress of the collision are thought to have resulted in plastic deformation in the diamond crystals. ...
