Kreuzberg (Rose Quartz Cliff), Pleystein, Upper Palatinate, Bavaria, Germany
Strengite is a very rare hydrated iron phosphate which is not usually seen in crystals, but rather as botryoidal rounded masses. It is in solid solution series with variscite where variscite is typically green and strengite is pink or purplish. These crystals are white as well as large for the species. From the historic Pleystein area of Germany which produced the largest strengite crystals. This mine has long closed, these white crystals show a chubby prismatic form with wet-like luster and tiny striations on some of the crystal faces. While not richly colored, these have excellent crystal details and are nicely sized for the mineral.
