Quick Answer
June has three official birthstones: pearl, alexandrite, and moonstone. Pearl is an organic gem from mollusks — nearly all sold today are cultured, not found by chance. Alexandrite is a rare color-change chrysoberyl, green in daylight and red under incandescent light. Moonstone is a feldspar prized for adularescence, a soft glow that seems to float beneath its surface. All three make meaningful June gifts, each with its own look and care routine.
What Are June's Birthstones?
June is one of a handful of months with more than one official birthstone: pearl, alexandrite, and moonstone. Pearl has anchored the June list the longest; alexandrite joined as a modern addition in the 1952 update; moonstone rounds out the trio as a softer, budget-friendly option. Each comes from a different source and needs a different care routine.
- Pearl — an organic gem grown inside mollusks, Mohs 2.5–4.5; nearly all pearls sold today are cultured
- Alexandrite — a color-change variety of chrysoberyl, roughly Mohs 8.5; natural stones are genuinely rare
- Moonstone — a feldspar known for its glowing adularescence, Mohs 6–6.5
- All three can be found as lab-created or treated versions at a lower cost than top natural material
What Is Pearl, and Why Are Almost All Pearls “Cultured”?
Pearl is June's most traditional birthstone — an organic gem formed inside a mollusk rather than mined from rock. Today, nearly every pearl sold commercially is cultured, meaning a farmer inserts an irritant to prompt a shell to form a pearl, rather than one turning up naturally by chance. At Mohs 2.5 to 4.5, pearl is soft and needs gentler handling than a moissanite or hard-gemstone piece.
- Cultured freshwater and saltwater (Akoya) pearls make up nearly all of today's market; natural pearls found by pure chance are exceptionally rare
- Color ranges from classic white and cream to pink, gold, and black, depending on the mollusk and water
- Keep pearls away from perfume, hairspray, and lotion, which can dull their surface over time
- Put pearls on last when getting dressed, and wipe them with a soft cloth after wearing
What Is Alexandrite, and Why Is It So Rare?
Alexandrite is a color-change variety of chrysoberyl — green to bluish-green in daylight, shifting to red or purplish-red under incandescent light. Natural alexandrite is exceptionally rare and priced accordingly; it was first documented in Russia's Ural Mountains in the 1830s. Lab-created alexandrite shares the same chemistry and color-change effect as a true synthetic, at a fraction of the cost.
- The color shift comes from trace chromium interacting differently with daylight versus incandescent light
- Natural stones large enough to facet are genuinely scarce; most fine alexandrite jewelry relies on small accent stones
- Lab-created alexandrite is chemically the same as the natural stone, just grown instead of mined
What Is Moonstone, and What Makes It Glow?
Moonstone is a feldspar gem known for adularescence — a soft, billowy glow that seems to float beneath the surface as the stone catches the light. It ranges from colorless to gray, peach, or green, and rates Mohs 6 to 6.5, softer than moissanite and best suited to settings that protect the stone from hard knocks.
- The glow comes from light scattering between microscopic layers inside the stone, not from faceting
- Blue-sheen “rainbow” moonstone from Sri Lanka and India is the most sought-after variety
- At Mohs 6–6.5, keep moonstone away from hard knocks and store it apart from harder stones
How to Wear a June Birthday Look in Sterling Silver and Moissanite
We don't currently stock pearl, alexandrite, or moonstone in our catalog, so we style June birthdays with near-colorless moissanite set in 925 sterling silver instead — a bright, everyday look, not a birthstone substitute. A dainty pendant, nameplate, or symbolic charm makes a personal, giftable piece for a June birthday.
- A glowing circle pendant echoes moonstone's soft light without needing an actual moonstone
- A nameplate or initial piece adds a personal touch that a stock birthstone charm can't
- A hamsa or symbolic pendant works well as a meaningful gift for a friend, sister, or partner
- If you want a real pearl, alexandrite, or moonstone accent, the custom route below is the honest way to add it
Here are a few everyday pieces from our current necklace lineup that work well for this kind of personal, giftable look:

Want an Actual June Birthstone Piece? We Can Make One
If you want a genuine pearl, alexandrite, or moonstone piece — a birthstone pendant, a personalized initial charm, or a memorial design — we take custom requests. Share your idea through our custom design inquiry page, and we'll work with you on stone, setting, and sterling silver details before anything is made.
This is where the personal side of a birthstone gift comes in. A June birthday piece doesn't have to be a plain solitaire — a small accent set beside an initial, a number, or a hand-picked design carries more meaning than a stock item. If you're curious how other months in this series are covered, we've also written guides for May's emerald and February's amethyst.
Frequently Asked Questions
Is pearl a good stone for everyday wear?
It depends on how it's worn and handled. At Mohs 2.5–4.5, pearl is softer than most gemstones and can scuff or dull with rough contact, so it works best in earrings, pendants, and necklaces rather than a ring worn during manual work. Wiping pearls with a soft cloth after wearing and storing them separately helps them stay in good condition longer.
Does MYNSU sell pearl, alexandrite, or moonstone jewelry?
Not in our standard catalog — we currently stock moissanite and 925 sterling silver pieces, some with pavé cubic zirconia accents. If one of June's birthstones is specifically what you're after, our custom design process can build a one-off piece around it; reach out through our custom design inquiry page to start that conversation.
Is lab-created alexandrite a real alexandrite?
Yes. Lab-created alexandrite has the same chemical structure and color-change effect as natural alexandrite — it's grown in a lab rather than mined, and it isn't a simulant like moissanite or cubic zirconia. Because natural alexandrite is so scarce, most affordable alexandrite jewelry on the market today uses the lab-created version.
Why does moonstone's glow look different from moissanite's sparkle?
They're two different optical effects. Moonstone's adularescence comes from light scattering between thin internal layers, producing a soft, moving glow rather than distinct flashes. Moissanite's brilliance comes from its cut and high refractive index, producing bright, faceted sparkle. Neither effect is “better” — they simply read very differently in a piece of jewelry.
