System:MonoclinicColour:Blue-green
Name:Named in honor of Michel Camerola, French mineral collector.


Cyanotrichite Group.
Closely related to carbonatecyanotrichite, less so to cyanotrichite.

The Sb:S ratio appears to be variable (Walenta, 1995). Type camerolaite has S:Sb = 1:1.44; material from the Clara mine has 1:0.64 (Walenta, 1995), although both have nearly identical X-ray powder diffraction patterns; the refractive indices of the Clara material are lower, however, due to the lower Sb content.
