This piece was cut from a listwanite. After making the cuts I noticed that there was a slip fault line going through the rock where you can clearly see the offset in the minerals on the front and back faces. This rock is like a geological history lesson wrapped up in a beautiful piece of art. The beautiful colors of this rock were formed through metamorphism of ultramafic rocks (typically peridotites) forming the striking contrast of the green, grey and black minerals. Then the area where this rock formed was faulted and the ground shifted. The gap formed after this process was filled with silica materials and over time forming quartz.

Rock type: Listwanite

Chemical composition: Listwanites are formed from ultramafic rocks that are partially altered to carbonate minerals. The main minerals found in listwanites are quartz, serpentines, and carbonates.
