Emerald green
4 - 4½
Specific Gravity:
3.725 (Calculated)
Crystal System:
Originally named for its (apparent) triclinic symmetry and its polymorphism with atacamite.
A synonym of Clinoatacamite
Originally thought to be a separate, triclinic polymorph of atacamite, clinoatacamite and paratacamite, and visually indistinguishable from the latter two.

Discredited 5 years after publication as twinned clinoatacamite (IMA Proposal 15-A).

Note that a small part of the lot that contained "anatacamite" was also sold in 2008 as paratacamite (Tony Nikischer information).
