Mimetite - Sold

Mimetite is a lead arsenate chloride. The mineral name comes from the Greek for imitator, since it resembles pyromorphite (Beudant, 1832). Mimetite typically forms aggregates of thin crystals, and globular growths.

When miners re-entered the lead rich areas of Ojuela in 2007, they began finding large quantities of mimetite. This specimen dates to 2009, when a significant find of green mimetite balls with wulfenite came out. This piece has green balls to 8 mm, with one wulfenite crystal 6 mm long. There is minor chipping to the tip of the wulfenite, but this does not distract from the specimen. The matrix consists primarilly of quartz, with iron oxide staining. Choice.
