About Menzerite-(Y)
Formula:
(Y2Ca)Mg2(SiO4)3
Colour:
Brown in thin sections, megascopically black
Lustre:
Vitreous
Hardness:
6½ - 7
Specific Gravity:
4.31 (Calculated)

Member of:
Name:
Named in honour of Georg Menzer (4 May 1897, Riga, German Empire - 13 October 1989, Gauting, Germany), crystallographer who was the first to solve the crystal structure of garnet in 1925. The suffix/modifier follows the Levinson rule for species with essential REE indicating, in this case, a predominance of yttrium.
