Birthstone charms link each month to a specific gemstone or stones, and the stone’s meaning is a symbolic association rather than a fixed fact.
A birthstone charm works as a small, wearable reminder of the month someone was born — or of a person they want to keep close. What each month’s stone means, though, depends on which list you’re reading. The Gemological Institute of America (GIA) and The Old Farmer’s Almanac both publish birthstone guides, and they don’t match perfectly: several months carry more than one accepted stone, and “traditional” assignments often differ from modern ones.
That’s the honest starting point. The table below lays out the commonly used US list and the meanings most often attached to each stone, followed by the two mistakes that trip up most buyers.
The Month-By-Month Birthstone Meanings
There is no single universally “official” birthstone set. The list below is the one most US sources use, paired with the symbolic meanings most frequently attached to each stone.
| Month & Stone | Common Meaning | Also Accepted |
|---|---|---|
| January — garnet | Protection, safe travel, trust | None |
| February — amethyst | Courage, calm, clarity | None |
| March — aquamarine | Health, tranquility, renewal | Bloodstone |
| April — diamond | Love, strength, everlasting love | None |
| May — emerald | Growth, wisdom, rebirth | None |
| June — pearl | Purity, innocence, wisdom | Alexandrite, moonstone |
| July — ruby | Passion, protection, vitality | None |
| August — peridot | Strength, prosperity, good fortune | Spinel |
| September — sapphire | Wisdom, loyalty, sincerity | None |
| October — opal | Confidence, hope, creativity | Tourmaline |
| November — topaz | Affection, joy, abundance | Citrine |
| December — turquoise | Protection, success, well-being | Tanzanite, zircon |
Why The Meanings Aren’t Set In Stone
Birthstone meanings are cultural associations, not documented properties of the gems themselves. The GIA frames birthstones as a shared tradition that has shifted over time, and the overlaps in the table above come from centuries of that drift.
The clearest example is June, which modern guides list three ways — pearl, alexandrite, and moonstone — and none of them is wrong. A reader hunting for a June charm can pick whichever one suits the recipient’s taste, then describe it in their own words rather than quoting a fixed meaning.
September is the one month most sources agree on. Sapphire’s association with wisdom and loyalty is consistent across guides, which makes it an easy pick for anyone who wants a stone with a steady reputation.
If you’re shopping, the takeaway is simple: pick the stone, then pick the meaning that feels right for the person. A comparison of ready-made options — including how charms are set and what stones actually show up in stock — is laid out in this roundup of the best birthstone bracelets for gifting.
Mistakes That Lead To The Wrong Charm
The two biggest errors both come from treating one guide as the only guide. The first is assuming every month has exactly one stone; as the table shows, six months have alternates. The second is quoting a meaning as a fact.
Meanings vary by source, sometimes noticeably. GIA’s birthstone reference and The Old Farmer’s Almanac both cover the same twelve months, yet their framing and stone lists differ in places. Neither is wrong — they’re drawing on different traditions.
- Check the month, not the stone, first. Some months (March, June, August, October, November, December) have alternates.
- Treat meanings as symbolic. “Protection” or “courage” describes tradition, not a property of the gem.
- Ask which list the seller uses. A June charm might hold a pearl, an alexandrite, or a moonstone — all defensible.
Once those two traps are cleared, the choice comes down to color, cut, and budget rather than correctness.

Common Questions
Does every month have only one gemstone?
No. Six months carry more than one accepted stone. March pairs aquamarine with bloodstone, June adds alexandrite and moonstone to pearl, and August, October, November, and December each list at least one alternate. Reputable guides disagree on which is “primary,” so all of them are considered valid picks.
Are the meanings based on any science?
No. Meanings like protection, courage, and loyalty are cultural traditions attached to the stones over time, not measurable properties. Different reference sources describe the same stone in different words, and some months disagree on what a stone symbolizes, so treat any meaning as a suggestion rather than a definition.
Which months have the most disagreement between sources?
June is the clearest case, with pearl, alexandrite, and moonstone all appearing as valid options depending on the list. March, August, October, November, and December also carry alternates. September is the month most sources treat consistently, with sapphire as the standard assignment.
