Giving a gift of significance can be extra special. Birthstone jewellery is the perfect gift for someone's birthday, for a bridesmaid to say thank you, or just to keep for yourself! The custom of wearing birthstones gained popularity in Poland during the 15th century. Tradition was that everyone wore the birthstone that represented the month they were in, since the power of a gemstone was heightened during its own month. For greatest effect, individuals needed to own an entire set of twelve - perhaps you should too!
