Garnet is the January birthstone (and also the Aquarius birthstone). Garnet is the term used to refer to a group of silicate minerals that have similar physical attributes, but different chemical structures. 

The word garnet comes from the 14th‑century Middle English word gernet, which means 'dark red'. It may also have its origins in the Latin word granatus, from granum ('grain, seed'). It is said by some that this is a reference to 'pomegranate' (punica granatum), a fruit with seeds that resemble garnet.

WHAT COLOUR IS THE JANUARY BIRTHSTONE?

Garnet is usually a red colour. However, because there are many different types of garnet, it can also appear in a multitude of colours, from yellow and orange to pink, blue and green.

Colour-changing garnet has also been discovered in Kenya, Madagascar and Tanzania. It’s a rare and beautiful form of garnet that changes colour depending on what light source is used. Generally, it appears greenish when under fluorescent light (such as indoors), but looks red or purple or reddish-purple when in incandescent light.
