Colorful specimen of green Brochantite and blue Cyanotrichite. These specimens are very hard to come by now as the locality is located within Grand Canyon national park. This copper mine began operation in 1892, stopped operation around 1907, and became a part of the national park in 1940. The specimen is likely over 100 years old!
