Strengite is a hydrous phosphate of iron. Nies (1877) named strengite after Professor Johan A. Streng (1830-1897), mineralogist at the University of Giessen (Germany). Strengite is a widespread phosphate mineral, typically forming small botryoids.

This strengite specimen features pale purple crystals to 5 mm; mostly flat-lying rather dull. A tiny cavity on the side of the piece hosts gemmy purple crystals to 4 mm. The matrix consists of altered triphylite and quartz. The base of the specimen has been sawn. From the collection of E.R. Laskowski (1949-2020), a mining engineer who retired to Tucson, Arizona. Earlier labels from Minerals Unlimited and Steve Pullman accompany the specimen.
