Almandine is found in rock forms and is up to 8% aluminum oxide by weight. Almandine is most abundant as a gemstone. The name comes from the Italian word that means red which refers to the color of this variety of garnet. The almandine crystal structure ranges from hexagonal to rhombohedral proportions. In color, they are usually found as a deep red with a brownish shade.
Almandine is converted into rust-red hematite by a natural process discovered in 1913 by Wohler and H.R. Schubert. In 1820, the production of synthetic garnet started and in the 19th century, the advanced technology of artificial heat treatment transformed it into Almandine artificially for gemstone quality use.

2. How Is It Formed?
The almandine garnet is formed in a fissure, an irregular crack from widening or widening cracks in the stone.
