Huge Rare Pink Calcite Twinned Crystal from Tonglushan Mine, Daye Co., Hubei, China

This is a very beautiful light pink, sharp and well-defined twin of calcite crystals sitting on a little bit of matrix of druzy calcite in perfect condition. The prominent crystal is quite gemmy, highly UV reactive (strong pink fluorescence), and phosphorescent (fluorescence lingers for 1-2s). These pink calcite twins were from a small pocket discovered several years ago. The calcites from this area are usually colorless or orangish red. Pink is definitely a rare one.
