Trolleite points Brazil (new stone in 2020) Relatively rare stone that you rarely see.

We don't really like the stone, but it is part of it, so that's why we recently bought it from the discoverer, who gave it the name "Trolliet".

Trolleite is a fairly rare mineral from the mineral class phosphates. It crystallizes in the monoclinic crystal system with the chemical composition Al4 [OH | PO4] 3 [4] and mainly develops solid to flaky aggregates that are colorless or light blue to light green in color. The mineral was first described in 1868 by Christian Wilhelm Blomstrand (1826–1897), who called it “Trolleit” in honor of the Swedish chemist Hans Gabriel Trolle-Wachmeister (1782–1871). Trolley shapes in metamorphic rocks such as amphibolite. So far, the mineral has been digested at the following locations: in Bundaberg (Queensland) in Australia; in Yamaguchi Prefecture on Honshu in Japan; in the Itremo massif of the province of Fianarantsoa in Madagascar; in the Eastern Siberian region (Transbaikalia) of Russia; in the western province of Rwanda; in the Swedish provinces of Skåne, Värmland and Västergötland; as well as in California (White Mountains), Colorado (Glendevey) and Virginia (Sprouses Corner) in the US.
