I really like rocks and different minerals so this exhibit at the Museum of Natural Science in Raleigh, NC is perfect for me. The top is: Pyrite “Sun” from Sparta, Illinois. The bottom is: Grossular Garnet from Coahuila, Mexico. I really love the colors and featured growth patterns. It is fascinating how these crystals and minerals form in such perfect shapes. There was another form of Pyrite in the same area that grew in perfect squares.
