Hodgkinsonite
# Hodgkinsonite

Hodgkinsonite is a rare zinc manganese silicate mineral $Zn_2MnSiO_4(OH)_2.$ It crystallizes in the monoclinic system and typically forms radiating to acicular prismatic crystals with variable color from pink, yellow-red to deep red. Hodgkinsonite was discovered in 1913 by H. H. Hodgkinson, for whom it is named in Franklin, New Jersey, and it is only found in that area.
