Birthstone by Month

You are buying a gift, picking a pendant or ordering a custom piece and want the right stone for someone's birth month. The field takes the month number, 1 through 12, and the matching stone appears below it. June is pearl, April is diamond, September is sapphire. What drives this is the calendar month, not the zodiac sign: they are separate traditions and their cutoff dates do not line up.

The list behind this page is the American one standardized in 1912 by the US jewelers association, which went on to become the trade reference in much of the world. It gives one stone per month, and that is where the confusion starts: several months later gained official alternates that do not show up here. March also takes bloodstone, June allows moonstone and alexandrite, October has tourmaline, November has citrine and December includes tanzanite and zircon.

Enter the month number only. Values outside the range are clamped to 1 or 12 with no warning, and decimals get rounded, so 6.6 returns July's stone. If the piece is for daily wear, weigh hardness before symbolism: pearl and opal scratch and dull easily, while sapphire and ruby handle an everyday ring. The page gives you the symbolic association and nothing else, with no judgment on authenticity, quality or price.
