All garnets share a common chemical structure but vary in chemical composition. Garnet is commonly found in highly metamorphosed rocks and in some ingeous rocks, forming under the same high temperatures/pressures that form these types of rocks. Garnet is also found in the rocks of contact metamorphism, subsurface magma chambers, lava flows, deep-source volcanic eruptions, and the soils and sediments formed when garnet-bearing rocks are weathered and eroded.

This stone has been used throughout history in jewellery and other decorative adornments such as windows in churches and temples. Greek philosopher, Plato even had his portrait engraved on a slab of garnet by a Roman engraver. Bohemia was once a tremendous source of garnet, and at one time, cutting, polishing, and mounting garnets was a very rich industry in that country. Many bohemian castles and churches had magnificent interiors decorated with garnet; bohemian garnets are famous even today, known for their small but beautiful stones set close to each other resembling a pomegranate. Garnet jewellery with stones still arranged in the traditional, tightly joined way is still found in the Czech Republic. The Anglo-Saxons were also fond of garnets and their jewellery was set with garnets mounted in many forms.

Garnets were highly popular in Europe in 18th and 19th centuries, they were frequently used for jewellery in the Victorian times. In Spanish astrology, the garnet once represented the sun and its name is believed to have derived from the Latin 'granatum', meaning pomegranate. In Old Spain, the pomegranate was a favourite and as a result, so was the garnet!
