Agates from the Middle-Class mine show a broader range of colors including red, yellow, purple, brown, blue, and black. They are known for showing strong concentric banding, chromatography and often contain spherulites. Agates from the Middle-Class mine also often contain druzy pockets with hematite and calcite crystals. Agates from this mine also contain a higher percentage of heat and stress fractures from the mining process and are considered less desirable so the prices tend to be more reasonable.
