Theoretically, pure Almandite Fe3Al2(SIO4)3 , should have an SG of 4.25 and an RI of 1.78. However, most almandites also contain some pyrope and the composition is frequently gradational. The chemical compostion is somewhat variable and many almandites may also contain varying amounts of spessartite or grossularite. In practice, garnets are usually referred to as almandite if they have an SG over 3.95 and an RI greater than 1.78. The color of almandite is usually dark toned with a more intense red inclining to red violet.
