The January birthstone is garnet — a deep red gem that has symbolised protection, friendship and loyalty for thousands of years. Most people picture wine-red garnets, but garnet is actually a family of minerals that comes in almost every colour, from vivid green tsavorite to glowing orange spessartine. Here is what the January birthstone means, its types and colours, where it comes from, how durable it is and how to choose one.

Garnet Meaning and History
The word garnet comes from the Latin granatum, meaning pomegranate, because small red garnet crystals look like pomegranate seeds. Garnet necklaces have been found in Egyptian burials dating back thousands of years; Romans carved signet rings from garnet; and medieval travellers carried garnets believing they protected against danger on the road. As the January birthstone, garnet stands for constancy, loyalty and deep friendship — a fitting stone for the first month of the year.
Types of Garnet
- Almandine – the classic deep red to purplish-red garnet; the most common.
- Pyrope – bright blood-red; famous “Bohemian garnets” from the Czech Republic.
- Rhodolite – raspberry-pink to purple-red, a pyrope–almandine mix.
- Spessartine – glowing orange; “Mandarin garnet” from Namibia and Nigeria.
- Tsavorite – vivid green grossular garnet from Kenya and Tanzania.
- Demantoid – green andradite with more fire than diamond; one of the rarest garnets.
- Hessonite – cinnamon-orange grossular.
- Colour-change garnet – blue-green in daylight, purple under incandescent light; very rare.
