Mimetite

An exceptional small cabinet specimen of beautifully crystallised Mimetite forming plumes of spherically terminated crystals covering a shallow vug in a pale yellow and rusty brown gossan matrix.  This is a museum quality example of the rounded form of Mimetite from the world famous Ojuela mine in Mapimí, Durango, Mexico.  Mimetite at Ojuela manifests in many colours, this being a rich orange yellow, but is quite difficult to describe.  Best you have a look at the accompanying photos now!  It could be likened to a cross between mustard and acidic lemon.  Around the periphery of the drusy mounds, which range up to about 7 mm across, the surface micro-crystals adopt a subtle orange hue.  The colour is uniformly consistent across the specimen but alters in tone due to shade between crystals and the diffraction of light through the outer translucent sucrosic texture.  A magnificent Ojuela Mimetite.
