This astonishing specimen from Navajún, Spain features a large over 1.5″ diameter Pyrite cube growing out of another moderately sized Pyrite cube with equally exquisite natural color, mirror-like luster, and geometrically perfect lines and angles. This rare, completely natural phenomenon grows out of a freestanding Basalt matrix. While most Pyrite forms a cubic habit, Spanish Pyrite is particularly known for the isolation of its crystals. This one-of-a-kind natural art piece will enrich your collection and shine on your shelf.
