Rosenbuschite

Named to honor Carl Henry F. Rosenbusch, a professor, geologist, and mineralogist from Heildelberg, Germany. Found in few countries including Norway Sweden, Guinea, the USA, Canada, Russia, and Greenland. Roschenbergite occurs “in some nepheline syenites and related pegmatites.”

Rosenhahnite

Leo Rosenhahn, an amateur mineralogist from California, USA who discovered the mineral, is the namesake for Rosenhahnite. At its type locality in Russian River in California, USA, Rosenhahnite occurs in veins within brecciated, garnet- and diopside-bearing metamorphosed sediments. Rosenhahnite can be found at additional localities including Japan, New Zealand, and Russia. It will fluoresce a light orange-pink under long-wave ultraviolet light.

Rossmanite

Named for George R. Rossman of the California Institute of Technology in California, USA for his work on the spectroscopy of tourmaline minerals. This member of the tourmaline group appears as pale pink, prismatic crystals. Notable localities for Rossmannite include in the lepidolite pegmatite at Rozna in Moravia in the Czech Republic, along with elbaite, beryl, topaz, and cassiterite, and can also be found as zones in elbaite from San Piero in Campo on Elba Island in Italy. There are other known localities including in Germany, Sweden, England, the United States, Canada, China, Vietnam, Russia, Tanzania, the Republic of Congo, Nigeria, Namibia, Mozambique, and Madagascar.
