Mimetite is a mineral species which falls under the apatite group. It is a lead arsenate chloride mineral.
It often occurs as small prismatic crystals, but it can also be found in botryoidal (grape-like) or reniform (kidney-shaped) forms.
Mimetite can occur in various colours, including yellow, orange, brown, and green. Mimetite forms part of a series with Pyromorphite and it can be difficult to differentiate between Pyromorphite and Mimetite without laboratory access.
