Serandite

This page is currently not sponsored. Click here to sponsor this page.
Formula:
NaMn2+2Si3O8(OH)
Colour:
Pale pink, salmon-red, salmon-orange, deep orange, rose-red, brown, colourless
Lustre:
Vitreous, Sub-Vitreous, Greasy
Hardness:
5 - 5½
Specific Gravity:
3.34
Crystal System:
Triclinic
Name:
Named in 1931 by Antoine François Alfred Lacroix after J.M. Serand, lighthouse keeper of the Island of Rouma, Los, who assisted collecting the mineral and who coincidentally had a rosey pink complexion.

The name was modified in 2015 from sérandite to serandite by IMA approval 15-E.
Pectolite-Sérandite Series. The manganese analogue of pectolite and the sodium analogue of tanohataite.

Compare also marshallsussmanite.
