About EuchlorineHide

Formula:
KNaCu3(SO4)3O
Colour:
Emerald-green; emerald-green in transmitted light.
Crystal System:
Monoclinic
Name:
From the Greek εΰχλωρος for "pale green," in allusion to its colour.
May form a group: "euchlorine group"; in this group the unit cell parameter a is very sensitive to the Na/K ratio.

Structurally related to fedotovite and puninite.
