Modern and traditional birthstones commonly overlap, but their entries can differ by month. Both lists include garnet for January and amethyst for February, while March and June show how the choices can vary across charts. [1] [2] [3] To go further, see Birthstones by Month: A Simple Guide to All 12.
That means you can use either list as a starting point rather than treating one as the only acceptable choice. For example, if you are comparing stones for a March birthday, check which chart you have in mind; if you are choosing a keepsake, let the recipient’s preference help guide you. [3] [4]
Where the lists agree—and where they vary
The easiest way to compare modern and traditional birthstones is to look for both shared entries and months with different options. January’s garnet and February’s amethyst are familiar points of overlap across the charts cited here. [1] [3]
March is a useful example of variation: one chart lists aquamarine as a modern stone, while another gives bloodstone as a traditional choice and a separate reference names aquamarine or bloodstone. [1] [3] [4] June also varies: cited charts include alexandrite as a modern entry and pearl or moonstone as traditional entries. [1] [2] [3]
These differences do not make a choice wrong. They show why it helps to say which list you are using when you compare stones, especially if you are looking at a particular month with more than one entry. [2] [3]
A practical way to use the comparison
Start with the birthday month, then check whether the chart labels its entries modern, traditional, or both. If two options appear, picture the recipient wearing or keeping each stone; for instance, a March gift could follow a chart that names aquamarine or bloodstone. [4]
You do not have to treat the chart as a rule. If one stone feels more personal, choose that one, and mention the convention only if it helps explain your choice. That keeps the comparison useful without letting a chart make the decision for you.
How do modern and traditional birthstones compare by month?
Month | Traditional list | Modern list |
|---|---|---|
January | Garnet [3] | Garnet [1] |
February | Amethyst [3] | Amethyst [1] |
March | Bloodstone [3] | Aquamarine [1] |
April | Diamond [3] | Diamond [1] |
May | Emerald [3] | Emerald [1] |
June | Pearl or moonstone [3] | Alexandrite [1] |
July | Ruby [3] | Ruby [1] |
August | Sardonyx [4] | Peridot [1] |
January and February match in these charts: both list garnet for January and amethyst for February. [1][3] March and June show clearer variation: the traditional entries are bloodstone and pearl or moonstone, while the modern chart lists aquamarine and alexandrite. [1][3] These are chart-specific pairings, not a universal rule; for example, another reference lists both aquamarine and bloodstone for March. [4]
The entries above give a side-by-side comparison for months where the cited charts provide pairings. August illustrates why the labels matter: one reference names sardonyx as traditional, while the modern chart names peridot. [4][1] June also has more than one traditional option in the chart shown, so the table preserves both rather than reducing it to one stone. [3]
For a month not shown, check the particular chart you are using before treating an entry as modern or traditional. You can compare the same month across the two columns—for instance, January and February have matching entries, while March and June differ in these examples.
Why can one month have more than one birthstone?
A month can have more than one birthstone because traditional and modern charts are distinct ways of assigning stones, and some charts list multiple traditional options. [2] [3] The names therefore depend on which chart or tradition you are using, rather than a single choice that applies across every reference. For the next step, see Birthstone Colors by Month: A Quick Color Chart.
Different charts reflect different conventions
A traditional chart may preserve several stones for the same month, while a modern chart may present a different set of monthly assignments. [2] [3] For example, one chart lists pearl and moonstone for June among its traditional entries. [3] Another reference also gives June as “Pearl or” in its traditional chart. [5]
That does not mean you need to treat one listing as an error. A chart is describing its own convention, so the same month can appear with multiple options or with entries that differ between references. [2] [3] If you see two stones named for one month, check whether the chart is labeling them as traditional, modern, or another kind of option before comparing the lists.
How to read a month with multiple entries
Look at the chart’s labels and wording, not just the month and stone names. A list that names more than one stone may be recording alternatives within a tradition, while another chart may separate traditional and modern assignments. [3] [5] Keeping those categories attached to the entries makes it easier to understand why two charts can both present different choices without implying there is one settled standard.
For instance, if you find a June chart that names pearl and moonstone, read both as options in that chart’s traditional listing—not as proof that every reference uses the same pair. [3] Comparing the chart labels first helps you avoid combining entries from different conventions into a single universal list.
When you are checking a particular month, use the chart that matches the tradition you care about and keep its labels with the stone names. That simple step makes comparisons clearer, especially when a reference offers more than one choice for a month.
Which birthstone should you choose?
Choose the stone tied to the tradition or chart that matters most to the person receiving it. If you are choosing for yourself, you can follow the list you grew up with; if it is a gift, a family or cultural connection may make one convention feel more personal.
When a chart gives a month more than one option, use the recipient’s taste as your guide. For June, for example, a traditional list may include both pearl and moonstone, so you could choose the one whose look you think they would enjoy wearing. [3] If the choice is between aquamarine and bloodstone for March, color and personal preference can help you decide. [4]
Make the choice feel personal
Think about how the stone will be used. For a piece of jewelry someone might wear often, consider which option suits their usual colors and style; for a small keepsake, a stone with a family connection may matter more than matching a particular chart. You can also ask a relative which birthstone tradition the family has followed, especially if you are continuing a long-standing gift custom.
If the recipient has a clear favorite, you do not need to treat the chart as a strict rule. A birthstone gift can still be meaningful when you choose the listed option they are most likely to enjoy, rather than the one you assume they should prefer.
Explain the convention
For a keepsake, say which convention you followed so the choice feels intentional. A short note such as “I chose pearl from the traditional June list” makes the reasoning clear, while “I picked aquamarine for your March birthstone because you love its color” connects the selection to the person. [3] [4]
If you are unsure which list a recipient recognizes, ask before buying or include a brief explanation with the gift. That small detail can prevent confusion when someone knows a different chart, and it keeps the focus on the care behind your choice.
Questions readers often have
Different birthstone entries can coexist because charts may follow different traditions or references, so a variation does not automatically make one choice wrong. [2] [3]
Why do birthstone charts sometimes disagree?
A chart’s entries reflect the convention it uses, and references may present different stones for the same month. [2] [3] For example, one traditional listing includes pearl and moonstone for June, while another reference records multiple historical entries for that month. [2] [3]
That means you may see different answers when you compare charts, even when both are accurately describing the convention they follow. If you are discussing a stone with family or shopping for a gift, you can simply name the chart or tradition behind your choice.
How can I tell which chart a list follows?
Check the chart’s labels or introduction before comparing a particular month. Some lists explicitly separate “traditional” and “modern” entries, while others organize stones by time frame or include several options together. [2] [3]
For instance, if a page groups Pearl and Moonstone under June, look for its note about whether it is presenting a traditional list, a modern list, or a wider set of historical choices. [2] Comparing the convention first helps you avoid treating a chart-specific difference as a universal rule.
Does a birthstone gift have to match a chart?
No—your gift can follow a chart, but it can also reflect what feels meaningful to the recipient. You might choose a stone in their favorite color, one connected to a family memory, or a piece they are more likely to wear.
If you do choose by a particular list, you can explain that choice in a card—for example, “I picked this because it appears on the traditional chart I used.” A personal reason can make the gift feel thoughtful without requiring everyone to use the same chart.
What should I do if two references give different answers?
Choose the reference whose convention fits your purpose, then use it consistently for that comparison. If you are buying a keepsake, you can also ask the recipient whether they have a preferred tradition or stone; the choice does not need to settle which chart is universally correct.
The simplest way to use both charts
Treat modern and traditional birthstone lists as complementary references, not competing rules. You can use either chart—or both—to find a stone that feels right for the recipient and the occasion.
For a birthday gift, start with the recipient’s birth month, then choose a listed stone that suits their taste. If they prefer a classic-looking piece, you might focus on the option they already recognize; if they enjoy a less familiar choice, another stone on a traditional or modern chart may feel more personal. The point is to make a thoughtful selection, not to prove that one chart is the only correct one.
You can also let the occasion shape your choice. For a small everyday gift, pick the stone the recipient is most likely to wear; for a keepsake, choose the one that carries a family or personal association. If you are unsure, ask which option they like, or choose a design that makes the stone’s color and setting the main appeal.
When you give the gift, a brief note can make your choice feel intentional: “I chose this stone from the traditional list,” or “I picked this one because I thought you’d enjoy its look.” You do not need to include a long explanation of the charts. A clear, personal reason is enough.
The simplest approach is to treat both lists as useful ways to choose, then select one stone that fits the person and the moment. For your next step, decide whether the recipient’s preference, the occasion, or a family connection matters most, and use that as your guide.
