May contain minor F substituting for OH.
Colour:
Light pink to rose-red, salmon pink, pale gray, brown
Crystal System:
Monoclinic
Name:
Named after Heikki Allan Väyrynen (18 May 1888, Pielisjärvi, Finland - 29 August 1956), professor of mineralogy, Technical University, Helsinki (Finland).
The manganese-beryllium-phosphate väyrynenite was first recognized in 1939 as a possible new mineral by Oleg von Knorring (1915-1994). However, it was first described as a new mineral by Volborth (1954), from Viitaniemi, Eräjärvi, Finland. Additional mineralogical data and a new chemical analysis were given by Mrose and von Knorring (1959).
