Garnet is not one stone but a family of minerals that share a crystal structure. Most people picture a deep red stone, but garnets also come in orange, green, yellow and pink, and they are the traditional birthstone for January.

What it is

The garnet group is made up of silicate minerals, with species including almandine (deep red), pyrope (red, often from Bohemia), spessartine (orange), grossular (which includes the green tsavorite), andradite (which includes the green demantoid) and uvarovite (a rare emerald green). Hardness runs from about 6.5 to 7.5 on the Mohs scale, depending on the species, which makes garnet a good choice for jewellery. Crystals typically form rounded, many-faced shapes called dodecahedra and trapezohedra.

Garnet is found in metamorphic rocks across the world, including India, Sri Lanka, the Czech Republic, Madagascar, Tanzania and the United States. It is also ground up and used as an industrial abrasive, in sandpaper and in water-jet cutting.

History and culture

The name comes from the Latin granatum, pomegranate, because small garnet crystals look like the seeds of the fruit. Garnets have been found in jewellery from the Bronze Age onward. Early medieval craftsmen in northern Europe made garnet cloisonne, in which thin slices of red garnet are set over patterned gold foil. The treasure from Sutton Hoo in England is a well-known example, and studies of garnets in such pieces suggest that the stones travelled a long way, some from India and Sri Lanka.

In the eighteenth and nineteenth centuries, Bohemian garnet jewellery, set with clusters of small red pyrope stones, was hugely fashionable in Europe, and Czech garnet-making remains a tradition.

Folklore has also given garnet stories. A tradition holds that Noah used a garnet as a lantern on the Ark, and another tells of garnets as travellers’ talismans. These are folk traditions rather than history.

Garnet is the January stone on both the modern and the traditional lists. See the January birthstone page.

What crystal traditions associate with it

In many crystal traditions, garnet is associated with energy, commitment and passion, matching its colour. It is linked with the root chakra, and with Capricorn and Aquarius in some zodiac stone lists, though sources vary. These are symbolic associations and not claims about effects.

How people use it

Garnet is worn as rings, earrings, pendants and beads, and its hardness makes it suitable for everyday wear. Antique Victorian pieces are collected. Some people choose garnet as a January birthday gift, or keep a tumbled stone in a pocket as a personal symbol.

Care and safety

  • Garnet is durable, and most species can be cleaned with warm water, mild soap and a soft brush.
  • Avoid ultrasonic cleaners for stones with inclusions or fractures, and avoid sudden temperature changes.
  • Keep it out of harsh chemicals.
  • Do not swallow stones or place them in drinks.

Sourcing

Garnet comes from many places, including small-scale mines in Africa and Asia. India and Sri Lanka have long traditions of garnet cutting. Ask about origin if you want to know how a stone was obtained.

Imitations

Red glass and synthetic stones are sold as garnet. A genuine garnet is often slightly included, with a depth of colour.

Frequently asked questions

↳ Are all garnets red?

No. The garnet group includes green, orange, yellow, pink and even near-colourless stones, though red is the most familiar.

↳ Why is garnet named after a pomegranate?

The name comes from the Latin for pomegranate, because clusters of small red crystals resemble the fruit's seeds.

↳ Is garnet hard enough for daily wear?

Most garnets have a hardness of about 6.5 to 7.5, which suits rings and bracelets with reasonable care.
