June is one of only three months (the others are August and December) that has three birthstones, giving you a variety of beautiful birthstone choices. The June birthstones are pearl, alexandrite and moonstone. June is a month for celebrations, be it weddings, anniversaries (55th year of marriage), graduations or birthdays. And what better way to celebrate than with a June birthstone. Those who were born in June are lucky to have three gorgeous birthstones to call your own.
