Specimen from the "Posey" Mine in Utah in which we see a piece rich in minerals where we can see a good group of greenish brochantite crystals, on which radioactive phurcalite crystals of yellow tones can be seen. The piece also has white Halotrichite crystals and possibly dark colored Coffinite. It is a very aesthetic specimen from the 60s with rare and radioactive minerals.
