About Trolleite
Hans Gabriel Trolle-Wachtmeister
Formula:
Al4(PO4)3(OH)3
Colour:
Light green, colorless, bluish green, (dark blue when included)
Lustre:
Vitreous
Hardness:
5½ - 6
Specific Gravity:
3.10

Name:
Named after Hans Gabriel Trolle-Wachtmeister (11 September 1782, Sweden - 11 July 1871, Kristianstad, Sweden), attorney general and chemist.
Usually massive translucent light green to bluish green masses with a greasy luster. May be very blue because of mixtures with scorzalite.
