Almandine is in the pyralspite garnet series along with pyrope and spessartite. The pyralspite group is aluminum-rich, contrasting the calcium-rich ugrandite series — which includes uvarovite, grossular, and andradite. As an iron aluminum silicate, almandine's chemical formula is Fe3Al2Si3O12 or Fe3Al2(SiO4)3.

Pyrope: Pyrope is the iron magnesium and aluminum silicate of the pyrope-almandine series in the Pyralspite group of the Garnet family. Its beautiful deep-red gem quality makes it one of the most popular. Pure pyrope is colorless, but its red color, sometimes very bright, is due to small quantities of chrome in the crystal structure.
