Properties Of Almandine Garnet

Specific Gravity: 4.318
Refractive Index: 1.830
Almandine is a known member of the Garnet Group of minerals that includes Almandine, Andradite, Grossularite, Pyrope, Spessartine, and Uvarovite. Almandine is considered the most variety. Almandine always contains some Spessartine and Pyrope elements which create a range that is wide of including brown, red-brown, purplish red, wine red, purple and deep red. Almandine is the iron aluminum garnet. Pure Almandine and Pyrope that is pure are in nature and most specimens are a definite percentage for the two. Silky inclusions may be present in many Almandine gems that are only noticeable under magnification. Nevertheless, material from Idaho, United States Of America and India is recognized to contain inclusions of asbestiform minerals such as pyroxene and amphibole which create a chatoyancy that produces a star that is 4-raid.
Almandine, like other varieties of Garnet, forms rounded crystals with 12 rhombic or 24 faces that are trapezoidal combinations of these and some other types. This practice that is crystal classic for the Garnet Group of minerals.
