Jewellery worn with birthstones is a super popular trend and we are regularly asked by email, phone or by our visitors to the studio 'What is my Birthstone', so we've put together this handy guide to the birthstones by month including their colour, meanings and interesting history and lore. Wearing your birth stone is a way of connecting to your birth month and was traditionally believed to bring you power and prosperity when worn in the month of your birth.
