Rhodolite garnet is the name applied to a mixture of pyrope and almandite. Rhodolite tends to be lighter in color than most other kinds of red garnets. It can be easily confused with rubies because of the similarity in color.

Refractive Index:1.75 - 1.77
Chemical Composition:Al2(SiO4)3
Hardness:7.25

Rhodolite garnets should be differentiated from its darker cousins red-like almandine and pyrope. The mixture of red and violet in rhodolites is highly desirable and popular. Purple or purple-red is the most expensive and sought color for rhodolite and large clean transparent stones are uncommon and valuable.

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.
