Agates from the Middle-Class mine show a broad range of colors including red, yellow, purple, brown, blue, and black. 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 lower than the High-Class mine. The mines have been closed since 2016 and agate collecting has been prohibited, so any rough or specimens are much less common to obtain.
