Chert, Siltstone & Chrysocolla

Chert, Siltstone & Chrysocolla


This is a print of the original watercolor painting. The print is scrupulously perfected and produced on the finest artist grade Moab Entrada cotton paper. 

An unlikely triad. The larger rock is composed of red chert, aka Jasper. It has a slight lacing of white quartz. This was found on the coast and most likely comes from a deep ocean bed. The blue/green rock is a copper ore with streaks of chrysocolla, which forms from the oxidation of copper deposits. It can be confused with turquoise if not for the visible crystalline structure and derivative nature to the copper that surrounds it. Lastly, a cubic piece of siltstone covered in romanechite dendrites. I've had this little rock for decades. Dendrites are not fossils, rather they're crystals occurring from manganese oxide, that grow in fractal patterns. This one has a beautiful pattern on it's prominent side.

This print does not come with a handmade frame, however I do sell framed originals at
