Birthstones and zodiac stones — what's the difference?
Your birthstone is fixed to your calendar birth month by the modern official list kept by the Gemological Institute of America and the American Gem Society — garnet for January, emerald for May, sapphire for September, and so on. It's a settled, standardized tradition, which is why the same stones appear on jewellers' charts everywhere.
Your zodiac stones are different: they're tied to your astrological sign, whose dates straddle two months, and they come from crystal lore rather than a single official register. Different traditions name different stones. The ones shown here are the crystals our own zodiac guides recommend for each sign — offered as tradition and inspiration, not as established fact.
