Technically October has two birthstones Opal and Tourmaline but we’ll be mainly focusing on the Tourmaline. Tourmalines are classed as semi-precious and measure 7 ½ on the mohs hardness scale (so not ideal for everyday wear). Tourmalines come in a myriad of different colours and can also be bi-coloured like Watermelon tourmaline (green and pink).
