May Birthstone: What It Is, Why Emerald, and What Else Counts (2026)

If you were born in May, your birthstone is emerald — full stop, no debate about the primary stone. What trips people up is everything around that fact: whether there's a second May birthstone, why emerald got the honor in the first place, and how it stacks up against rarer or more affordable green stones. This guide answers those questions directly, then walks through what to actually look for if you're buying or gifting May birthstone jewelry in 2026.

What Are the Two Birthstones for May?

Emerald and chrysoprase are the two stones most commonly listed for May. Emerald is the modern, universally recognized May birthstone used by jewelers today. Chrysoprase — an apple-green variety of chalcedony — shows up as May's alternate or “mystical” birthstone in some older birthstone traditions, though it's far less commonly sold or requested than emerald. If someone mentions a “second” May birthstone, chrysoprase is almost always what they mean.

What Is the Original Birthstone for May?

Emerald is the original and most historically consistent birthstone for May, with a documented association going back to ancient Rome and Egypt. Birthstone lists have shifted over centuries and across cultures — some historical European lists swapped in agate or chalcedony for various months — but emerald's tie to May has outlasted nearly every other assignment, which is why it's the stone modern jewelers and gemological bodies still use today.

Why Was Emerald Chosen for May?

Emerald was chosen for May because its green color mirrors the season it falls in — the height of spring in the Northern Hemisphere, when new growth is at its most vivid. Ancient cultures also linked emerald to Venus, the goddess associated with love and springtime renewal, reinforcing the seasonal connection. That symbolism of rebirth, fertility, and growth is also why emerald became associated with the zodiac sign Taurus, which spans most of May.

Emerald vs Chrysoprase: Comparing May's Two Birthstones

Emerald and chrysoprase share a green color family but differ sharply in mineral makeup, hardness, and price — here's how they compare side by side.

What Does the May Birthstone Mean?

Emerald traditionally symbolizes rebirth, love, and growth, themes that have followed the stone since antiquity. It was worn by Cleopatra, prized by Roman elites who linked it to Venus, and used by various cultures as a talisman for fertility and renewal. That symbolism is part of why emerald remains a popular choice for milestone gifts, not just birthdays — it reads as a wish for new beginnings as much as a color statement.

How Should You Choose May Birthstone Jewelry?

Choose May birthstone jewelry based on how you'll wear it, not just the color, since genuine emerald is a relatively soft, often-included stone for daily wear. A pendant or pair of earrings takes less impact than a ring worn every day, which matters more with emerald than with a harder stone like sapphire. If sensitive skin is a concern, look for hypoallergenic settings — AJLuxe's birthstone pieces are set in 925 sterling silver with 18K gold plating, priced $24.99–$79.99, specifically to avoid the nickel and base-metal reactions that cause irritation with cheaper costume jewelry.

What Are the 3 Rarest Birthstone Months?

June, December, and October are generally considered to have the rarest birthstones, thanks to their well-known alternate stones: alexandrite (June), tanzanite (December), and fine black opal (October). Alexandrite is prized for its rare color-change effect and is scarce in large, clean sizes; tanzanite is mined almost exclusively in one area near Mount Kilimanjaro in Tanzania; and top-quality black opal comes mainly from a single Australian mining district. May's emerald is genuinely rare in fine quality too, but because commercial-grade emerald is more widely available and routinely treated to improve clarity, it doesn't usually make a “rarest” list the way those three do.

How Should You Gift May Birthstone Jewelry?

Give May birthstone jewelry in a piece the wearer will actually reach for daily — a simple pendant or stud earrings beat a large statement ring for everyday durability. AJLuxe's birthstone necklace collection includes emerald-toned May designs set in hypoallergenic 925 sterling silver with 18K gold plating, which keeps the green birthstone look accessible without asking a giver to shop for a graded natural emerald. Every piece ships gift-ready, which matters for a birthday purchase that's often bought closer to the date than planned.
