My Daily Rock 26: Outstanding Urbanite Colors 1

A lucky score at Granite Paradise's sister location at our home near Mexico City! In 2007 I traded English classes to a guy who was demolishing his shop where he had made concrete/onyx tiles for almost 50 years. The floor had risen in thickness to where they couldn't work there anymore because of the fine layer of drippings added daily. I have several tons of this exotic urbanite, and this is a wall I built with the smallest gravel. Truely amazing material!
