About SeranditeHide

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.

Many of the lighter pink "serandites" are Schizolite. They can't be sorted visually. None of the deep oreange serandites are Schizolite. Compare also marshallsussmanite.
