Gemstones come in pretty much any colour you can think of and in every hue as well. They can add some subtle sparkle, a hint if colour or huge impact focal point to any piece of jewellery.
If you can't decide on your favourite colour or stone a good place to start is with your birthstone. A semi-precious or precious stone that is linked to your month of birth or star sign. You can find various lists of birthstones from modern to astrological but below lists the range of colours and properties of the traditional birthstones.
