Spessartine forms a solid solution series with the garnet species almandine. Almandine has nicknames of Oriental garnet, almandine ruby, and carbuncle. Metamorphism in this area was higher grade with almandine garnet forming. The almandine crystal formula is&colon; FeAl(SiO). Fine crystals of almandine embedded in mica-schist occur near Wrangell in Alaska. In the United States there are many localities which yield almandine. These volcanics contain chloritised cordierite and some have red almandine garnet. The harder species like almandine are often used for abrasive purposes. Connecticut has almandine garnet as its state gemstone. The typical eclogite mineral assemblage is garnet (pyrope to almandine) plus clinopyroxene (omphacite). The coarse varieties of almandine are often crushed for use as an abrasive agent. The minerals in aluminium-garnet group are almandine, grossularite, pyrope, and spessartine. Alternative names of eudialyte include&colon; almandine spar, eudalite, Saami blood. The 2.5-16 added Almandine Red and Astral Silver. Almandine is an iron alumina garnet, of deep red color, inclining to purple.
