5.5" Cubic Pyrite, Quartz & Galena Crystal Cluster - Peru

This is a nice specimen of galena and cubic pyrite on transparent quartz crystals from the the Huanzala Mine in Peru. The main pyrite cube has a beautiful shine and measures 1.3" wide. Galena can be seen coating many of the pyrite cubes.

Pyrite (or iron pyrite) is commonly referred to as Fool's Gold because its metallic luster and pale brass-yellow hue give it a superficial resemblance to gold. In the old mining days, Pyrite was sometimes mistaken for gold. Pyrite is the most common of the sulfide minerals with the chemical formula FeS2. Pyrite crystals occur in many shapes and habits. Smaller (druzy) crystal aggregates may give off beautiful glistening effects, and larger crystals may be perfectly formed, including fascinating cubes, penetration twins, and other interesting crystal forms.

Galena is a lead-based mineral and the primary ore of lead, and has been used for its lead content for thousands of years. Galena typically displays a gray metallic luster and forms cubes or octahedral crystals. The chemical composition of galena is PbS.

While galena will not pose a health hazard by sitting on the shelf or even from casual handling, we suggest washing hands following handling due to the mineral's lead content.
