This calcite specimen features "dogstooth" crystals, named for their pointy, tooth-like appearance. It was collected in 2021 in Hubei, China, and contains rust red phantoms in the center of every one of the countless crystals that blanket its surface. The shape of this piece is very mountain-like, and at its peak it displays large crystals with lovely red gradation. 

Locality: Tonglushan Mine, Daye Co., Huangshi, Hubei, China
