Ca₂Co(AsO₄)₂·2H₂O to Ca₂Mg(AsO₄)₂·2H₂O

Dark magenta colored crystals with a high luster fill a elongated vug along with a few small, clear Quartz crystals. Roselite and Wendwilsonite form a series and are indistinguishable by sight and must be analyzed for verification. Even then, both species can be found on a specimen or even as layers in the same crystal.

Condition: Good

Flaws: Some of the crystals are incomplete, mostly those along the edges of the vug.
