The Revoltosa is an obsidian claim/mine currently (2012) being worked for different kinds of obsidian. The mine is located about 15 km east of the village of San Andreas on Mount San Andreas which is the tallest mountain in the area. It is about 2 kilometers from the border with Nayarit province. It is located at an elevation of about 2000 Meters in a pine "forest". The mine produces pure black obsidian and a variety of "rainbow" colored obsidians. The workings are open cast and blocks of many hundreds of kgs are found. Some of the very best rainbow colored obsidian is found here as well as "golden sheen" obsidian. Also it is not far distant from one of the best old fire opal mines.
Information from Alfredo Banos, claim holder of the La Revoltosa mine 
This mine has produced much of the fine Mexican rainbow obsidian that has come to the market place during the last five to ten years. Dr. George Rossman of Caltech has determined that the coloring agent in the rainbow obsidian are tiny oriented crystals of hedenbergite.
