Hieronymus Theodor Richter
Formula:
Na(NaCa)Mg5(Si8O22)(OH)2
The richterite group minerals are defined as sodium-calcium amphiboles with 0.5 apfu < A(Na+K+ 2Ca) where Na or K is dominant, and with C(Al+Fe3++2Ti)<0.5 apfu. The W position may contain (OH), F or Cl.

Richterite is defined with
A position: Na dominant
C position: Mg dominant
W position: (OH) dominant.
Colour:
Brown to brownish-red, rose-red, or yellow, grey-brown, and also pale to dark green. dark green blue and grey blue
Lustre:
Vitreous
Hardness:
5 - 6
Specific Gravity:
3.1
Crystal System:
Monoclinic
Name:
Named in 1865 by Johann Friedrich August Breithaupt in honor of Hieronymus Theodor Richter [November 21, 1824, Dresden, Germany – September 25, 1898, Freiberg, Saxony, Germany], professor of chemistry at Freiberg University of Mining and Technology. He was the co-discoverer of indium.
Compare the chemically similar winchite and potassic-richterite.
