The June birthstone is Moonstone or Pearl. Moonstone is also the gemstone associated with the Zodiac sign Gemini. Shimmering Moonstone is created in nature in two layers which allows the light to enter the stone and give it its amazing translucence which is known as the rainbow effect. In ancient times, moonstones were believed to get this amazing light from the rays of the moon. The perfect gift for a June birthday, Moonstone Birthstone jewellery is also known as the travellers and is believed to protect those who travel.
