My Birth Stone
Garnet is the birthstone for the month of January & anniversary gemstone for the second year of marriage.
Garnet derived its name from the Latin word granatus, meaning like a grain, which refers to the mode of occurrence wherein crystals resemble grains or seeds embedded in the matrix. Garnet is a family of minerals having similar physical and crystalline properties.
Garnet is the name which can be applied to six similar mineral species, namely almandine, pyrope, spessartine, grossular, andradite and uvarovite. To further complicate matters, many garnets are actually a combination of these minerals. Rhodolite garnet for instance, is a combination of almandine and pyrope, and is sometimes referred to as pyrope-almandine garnet. There are also many trade names and other commonly used names which only adds to the confusion, such as Rhodolite, Tsavorite, Hessonite, Malaya, Mozambique, Mandarin, Ant-hill, Leuco, Hydrogrossular, Demantoid, Melanite, Topazolite, Thai. Other names such as "cape ruby" are simply misleading and deceptive. Some garnets also exhibit color change and stars.
