Pyrrhotite and Quartz
Santa Eulalia, Chihuahua, Mexico
Small Cabinet, 6.9 x 5.1 x 3.8 cm
Ex. Richard Heck
A solid mass of lustrous, brassy-yellow crystals of pyrrhotite, to 2.5 cm in length, is surmounted by a single quartz crystal on one side. The other side is solid pyrrhotite. The quartz is an unusual association on the pyrrhotite, and is lustrous and translucent. The back side has several small spheres of what might be iron oxides attached. Overall a great example of this old classic find
