June is one of only three months with three official birthstones. Here is the complete picture of what each one means, why June carries three, and how to choose between them.
June has three official birthstones: alexandrite, pearl, and moonstone. According to the Gemological Institute of America (GIA), June is one of only three months — alongside August and December — that has three birthstones. Pearl is the traditional choice, alexandrite is the most precious and rarest, and moonstone is prized for its luminous blue sheen. So when someone asks what is June birthstone, the honest answer is "all three — and you can choose any of them." Anyone born in June can wear any of the three, or all three. Browse June birthstone jewelry or read on for the complete guide to choosing between them.
June is one of only three months on the modern birthstone calendar with three officially recognized stones — sharing that distinction with August and December — and the abundance is no accident. It is the result of a centuries-long tradition that began with pearl, expanded in the 20th century to add alexandrite, and grew again to include moonstone — three stones with almost nothing visually in common, each carrying its own history, symbolism, and place in the jewelry tradition. For someone born in June, the embarrassment of riches is real: a traditional organic gemstone, a rare color-changing crystal, and a luminous feldspar that catches the light like the moon itself.
This guide covers all three June birthstones in depth. You will find the full june birthstone history, the june birthstone meaning for each of the three stones, a side-by-side comparison of durability, price, and best uses, and a decision framework for choosing the right June birthstone for an engagement ring, a birthday gift, or a piece worn for years. We treat alexandrite meaning, pearl birthstone meaning, and moonstone symbolism each in their own dedicated section so you can navigate directly to the stone that interests you most. We carry all three stones at Aquamarise in handcrafted designs — links to specific pieces appear throughout where relevant.
The short version: Pearl is traditional and softest. Alexandrite is rare, dramatic, and the most engagement-ring-suitable. Moonstone is affordable, ethereal, and best for occasional wear or protected settings. The right June birthstone depends on the wearer's preferences, the occasion, and how the piece will be worn day-to-day.
Why June Has Three Birthstones — A Brief History
The modern birthstone calendar was standardized in 1912, but pearl predates the list by centuries — and the additions came later as gemology and trade evolved.
The idea of associating gemstones with months is ancient. Many cultures have linked stones to seasons, zodiac signs, or birth periods for thousands of years. The version Americans recognize today, however, is much more recent. The modern birthstone calendar was standardized in 1912 by the National Association of Jewelers, an organization now known as Jewelers of America. That list has been updated several times since — and June is the month that has gathered the most additions.
The presence of three stones isn't a problem — it is the gift. June birthdays carry the option to choose the stone that fits the wearer, the occasion, or the budget, rather than being assigned a single stone by tradition. The three are different enough that almost no June birthday is poorly served by all three at once.
Alexandrite — The Rare Color-Changing June Birthstone
Alexandrite is the rarest June birthstone — discovered in 1830, scarcer than diamond, and famous for changing color from green to red depending on the light. Among the three, alexandrite as a june birthstone holds the highest standing for collectors and engagement rings.
Alexandrite is a variety of the mineral chrysoberyl, distinguished from all other gemstones by a single property: strong color change under different light sources. In daylight or under fluorescent light, fine alexandrite appears green to teal-blue. Under incandescent or candle light, the same stone shifts to red, raspberry, or deep purple. The change is not a trick of polishing or a coating — it is an optical phenomenon caused by the way alexandrite's chemistry absorbs and transmits different wavelengths of light, an effect called pleochroism in combination with chromium content.
Natural alexandrite was first discovered in 1830 in the Ural Mountains of Russia and was named after the future Tsar Alexander II. The Russian deposits were largely exhausted within decades, and although alexandrite has since been mined in Brazil, Sri Lanka, and several African countries, fine natural alexandrite with strong color change above one carat remains rarer than diamond. The GIA's alexandrite reference notes that fine alexandrite is "one of the more expensive colored gems" because of its scarcity, particularly in larger sizes. Most alexandrite jewelry today uses lab-grown stones, which are visually identical, considerably more affordable, and entirely appropriate for daily wear.
Symbolism & meaning: The alexandrite June birthstone is associated with balance, transformation, and adaptability — themes drawn directly from its color change. The stone is often given as a symbol of the wearer's capacity to navigate different environments, moods, and seasons of life without losing themselves. It is also linked to good fortune and to clarity of perception, particularly the ability to see situations from multiple perspectives. For deeper context on alexandrite's properties and durability, see our guides on whether alexandrite is good for an engagement ring and whether synthetic alexandrite changes color.
Best for: Engagement rings, anniversary pieces, statement gifts, and any wearer who wants something genuinely uncommon. With a Mohs hardness of 8.5 — comparable to sapphire — alexandrite stands up to daily wear without difficulty.

Alexandrite contains trace amounts of chromium that absorb light strongly in the yellow region of the spectrum. Under daylight (which is rich in blue and green wavelengths), the chromium reflects green light, so the stone reads green. Under incandescent light (which is rich in red and yellow), the chromium reflects red light, so the stone reads red. The effect is the strongest known color change in any gemstone, and it is the entire reason alexandrite was singled out as worth adding to the June birthstone list in the mid-20th century. For more on this, see our companion post: alexandrite vs sapphire — which gemstone feels more unique.
Pearl — The Original June Birthstone
The only organic gemstone among the three June stones — and the only one that grows inside a living creature.
Pearl is unique among the June birthstones — and unique among gemstones generally — in being organic rather than mineral. The pearl June birthstone has the longest history of the three, with associations dating back centuries. A pearl forms inside the soft tissue of a living mollusk (an oyster, a freshwater mussel, or another shell-bearing creature) when an irritant becomes trapped inside the shell. The mollusk responds by coating the irritant with layers of nacre, the same material that lines the inside of its shell. Over months or years, those layers build up into a pearl. The same process produces the iridescent rainbow sheen visible on the inside of a shell — and on the surface of a pearl.
Pearls come in two broad categories: natural pearls, which form spontaneously and are extraordinarily rare today, and cultured pearls, which are produced by deliberately introducing an irritant into a farmed mollusk. Cultured pearls account for nearly all pearl jewelry on the market and include four major types — Akoya, freshwater, South Sea, and Tahitian — distinguished by the species of mollusk, the water environment, and the resulting size, shape, and color. Pearls range from white and cream to pink, lavender, gold, silver, and deep black, with each color tied to a specific mollusk species.
Symbolism & meaning: Pearl symbolizes purity, wisdom gained through experience, and beauty that emerges from challenge. The pearl-formation metaphor — a mollusk transforming an irritant into something precious — is one of the oldest and most evocative in gem mythology. Pearls have been associated with the moon, with the ocean, with feminine power, and with the calm that comes from emotional maturity. In Christian tradition, pearls represent integrity and the soul; in Eastern traditions, they are linked to longevity and prosperity.
Best for: Sentimental gifts, heirloom pieces, anniversary jewelry, and rings worn for special occasions rather than daily life. Pearl's softness — Mohs 2.5 to 4.5, far lower than any crystalline gemstone — means pearl jewelry requires more care than alexandrite or moonstone. Pearl rings are wearable but should be removed before exercise, gardening, washing dishes, or applying lotions and perfumes. With reasonable care, pearl jewelry lasts generations.

Pearls are gentle stones and require gentle care. Wipe pearls with a soft cloth after wearing to remove skin oils and lotion residue. Never use ultrasonic or steam cleaners — both can damage nacre. Avoid contact with perfume, hairspray, household chemicals, and chlorinated water. The traditional jeweler's rule for pearls is "last on, first off": put pearls on after dressing and applying any cosmetics, and remove them before undressing. Stored properly in a soft pouch separated from harder gemstones, pearl jewelry retains its luster for decades.
Moonstone — The Luminous Third June Birthstone
Named for its blue sheen — a floating glow that catches the light like moonlight on water.
Moonstone is a variety of feldspar — specifically, a mineral called orthoclase with thin layers of another feldspar called albite layered through it. The interaction of light with these layers produces moonstone's defining feature: adularescence, a soft floating glow that appears to drift across the surface as the stone is moved. Fine moonstone shows a strong blue sheen against a near-colorless body; lower-quality moonstone shows a white or silvery glow. Some moonstones — particularly those from India — display a rainbow adularescence with multiple colors visible at different angles. For more on moonstone's deeper symbolism, see our moonstone meaning guide.
Moonstone has been used in jewelry for thousands of years and appears in Roman, Greek, Hindu, and other ancient traditions. The name comes directly from the appearance: ancient observers thought the sheen resembled trapped moonlight, and the stone was associated with lunar deities across multiple cultures. The Old Farmer's Almanac notes that Pliny the Elder, the Roman natural historian, gave moonstone its name and wrote that its shimmery appearance reflected the moon's phases. In modern times, moonstone enjoyed a particular popularity during the Art Nouveau period of the late 19th and early 20th centuries, when its dreamlike quality fit the era's aesthetic precisely. It has remained a favorite for nature-inspired and bohemian jewelry ever since.
Symbolism & meaning: Moonstone is the gem of intuition, feminine energy, new beginnings, and emotional clarity. The lunar association runs through all of these — the moon as a symbol of cycles, of inner knowing, of the rhythm beneath rational thought. Moonstone is often given to mark transitions: graduations, new chapters, weddings, and births. In some traditions, it is considered a stone of safe travel, particularly for travel by water at night. Across nearly every culture that has used moonstone in jewelry, it has been linked to women, motherhood, and the nurturing aspects of personal power.
Best for: Engagement rings in protected settings (bezel rather than prong), nature-inspired pieces, gifts marking transitions, and any wearer drawn to ethereal or dreamlike aesthetics. With Mohs hardness 6 to 6.5, moonstone is wearable in a ring but more vulnerable to chipping than alexandrite. Bezel settings, lower profiles, and softer everyday handling extend a moonstone ring's lifespan considerably.

Each Stone in History — How Pearl, Alexandrite, and Moonstone Earned Their Place in June
Three stones, three completely different paths into the same month on the calendar.
The June birthstone calendar is the result of three independent histories converging on the same month. Pearl arrived first by tradition, alexandrite by trade decision, and moonstone by mythological association. Each stone's path explains something about why it carries the symbolism it carries today.
Pearl as the June birthstone traces back to ancient and medieval European traditions that linked organic gems and ocean-derived materials to the early-summer months. Pearls have been prized in jewelry across virtually every culture with access to the sea — Roman, Greek, Persian, Chinese, Indian, Polynesian — and were considered a primary status symbol in Western Europe well before the modern birthstone calendar existed. By the time the National Association of Jewelers compiled the 1912 list, pearl was already the obvious June stone. The connection between pearl and June was not invented in 1912; it was formalized. Pearl as the June birthstone is therefore the most historically dense of the three associations, with centuries of accumulated tradition reinforcing the link.
Alexandrite as the June birthstone is younger but no less interesting. The stone itself was unknown to the world until 1830, when it was discovered in emerald mines in the Ural Mountains of Russia. Named after the future Tsar Alexander II — whose birthday allegedly fell shortly after the discovery — alexandrite quickly became a favorite of the Russian imperial family because its red and green color change matched the imperial military colors. After the Russian deposits were largely exhausted in the late 19th century, alexandrite remained extraordinarily rare and expensive, available primarily through brief discoveries in Brazil (1987), Sri Lanka, and parts of East Africa. By the mid-20th century, the American Gem Society and the Jewelry Industry Council had added alexandrite to the official June list specifically to give the month a precious crystalline gemstone alongside its traditional pearl — a buyer who wanted a "real" gemstone for a June birthday could now choose alexandrite without violating tradition.
Moonstone as the June birthstone draws on the longest mythological tradition of the three. Greek and Roman writers associated moonstone directly with lunar deities — Selene and Diana respectively — and Hindu tradition treated moonstone as solidified moonbeams. The stone's name in nearly every major language references the moon directly. The connection between the moon and June is itself ancient: the summer solstice falls in June, and the visible behavior of the moon shifts notably around that period. When moonstone was added to the modern June birthstone list, it brought thousands of years of mythological weight with it. Moonstone is the stone in this trio with the most spiritually loaded history — which is part of why it has remained popular for nature-inspired and bohemian jewelry into the present day.
The most common point of confusion among June birthstones is the alexandrite vs moonstone question — particularly for buyers who want a stone that "shifts" or "changes" depending on the light. The two phenomena are entirely different. Alexandrite displays true color change: the stone is one color in daylight and a different color under incandescent light, due to its chromium content interacting with different parts of the visible spectrum. Moonstone displays adularescence: a sheen of light that floats across the surface as the stone moves, caused by the layered feldspar structure scattering light. Alexandrite changes color; moonstone shows a surface glow. Neither is a substitute for the other, and both are correct June birthstones — but a buyer looking for one will not be satisfied by the other.

Choosing the Right June Birthstone — A Decision Framework
Three routes, three different stones. Pick the one that matches the wearer, the occasion, and the way the piece will be worn.
For an Engagement Ring → Choose Alexandrite
An engagement ring is worn daily for years and needs a stone that holds up. Alexandrite (Mohs 8.5) is the only one of the three that performs reliably as a daily-wear engagement ring without special precautions. Lab-grown alexandrite delivers identical visual quality at a fraction of the cost of natural — the right choice for almost every modern engagement ring buyer. Browse alexandrite engagement rings.
For a Sentimental Gift → Choose Pearl
Pearl carries the deepest traditional resonance of the three June stones and is the right choice when the gift is meant to mark something — a birthday, a graduation, a milestone, a generational handoff. Pearl rings are perfect for occasion wear; pearl pendants and earrings offer pearl beauty without the daily-wear concerns that come with rings. Browse the June birthstone collection.
For Personal Style → Choose Moonstone
For a recipient drawn to ethereal, nature-inspired, or bohemian aesthetics, moonstone delivers a quality of light that neither alexandrite nor pearl can match. Best in protected settings for ring wear, or as a pendant where its blue sheen has space to catch the light. Strongest pick for a wearer who values feeling over conventional preciousness. Browse moonstone rings.
Wearing All Three — The Multi-Stone Approach
June birthdays don't have to choose. The strongest jewelry pieces sometimes include two or three of the stones together.
Because June carries three official birthstones, June birthdays have an option no other month does: wearing more than one June stone in the same piece, or as a coordinated set across multiple pieces. This is especially powerful for milestone gifts — a 30th or 40th birthday, a significant anniversary, or a mother's gift with all three stones representing different aspects of the wearer's identity. A ring with alexandrite and moonstone pairs daily-wear durability with ethereal sheen; a pendant with all three captures the full spectrum of June symbolism in a single object.
The multi-stone approach also works as a gift-giving strategy across years. A pearl piece for a younger birthday, alexandrite for an engagement, moonstone for a wedding or anniversary — each one drawing on June's tradition without repeating the same stone. For a couples piece that incorporates the June birthstone alongside a partner's stone, our Aquamarine & Crescent Moonstone Engagement Ring combines March (aquamarine) and June (moonstone) for couples whose birthdays fall in those two months — a quietly meaningful gesture for the right pair.
Caring for June Birthstone Jewelry — Three Stones, Three Approaches
Each of the three June birthstones has different durability and care requirements. Treating them all the same way is the fastest way to damage the softer two.
The single biggest practical fact about June birthstone jewelry is that the three stones have radically different durability profiles. Alexandrite at Mohs 8.5 is essentially as durable as sapphire and can be cleaned and worn the same way. Pearl at Mohs 2.5 to 4.5 is one of the softest gemstones in regular jewelry use and requires meaningfully gentler handling. Moonstone at Mohs 6 to 6.5 sits between the two but is also susceptible to internal cleavage if struck sharply. A care routine that works for one will not work for all three.
| Action | Alexandrite | Pearl | Moonstone |
|---|---|---|---|
| Daily wear | Safe | Avoid | OK with care |
| Warm soapy water | Yes | Soft cloth only | Yes (gentle) |
| Ultrasonic cleaner | Generally safe | Never | Avoid |
| Steam cleaner | Generally safe | Never | Avoid |
| Chlorine / chemicals | Avoid | Never | Avoid |
| Storage | With care | Soft pouch, separated | Soft pouch, separated |

Frequently Asked Questions About the June Birthstone Trio
Ten questions covering meaning, color, durability, and how to choose between the three June birthstones.
What is the June birthstone?
June is one of only three months — alongside August and December — with three official birthstones: alexandrite, pearl, and moonstone. Pearl is the traditional June birthstone, dating back centuries. Alexandrite was added in the 20th century. Moonstone is recognized as the third option. Anyone born in June can wear any of the three. Browse: June birthstone jewelry.
Why does June have three birthstones?
The modern American birthstone calendar was standardized in 1912, with pearl as June's stone. Alexandrite was added in the 20th century as a precious gemstone alternative to organic pearl. Moonstone has been recognized as a third option for its long historical association with June and its distinctive optical properties. June is one of only three months — alongside August and December — with three officially recognized birthstones.
What is the June birthstone color?
Each of the three June birthstones has its own characteristic palette. Pearl is most often white or cream, but also pink, gold, silver, lavender, and black. Alexandrite is famous for its color change — green or teal in daylight, red or purple under incandescent light. Moonstone is typically white or near-colorless with a blue or rainbow sheen called adularescence.
What does the June birthstone mean?
Pearl represents purity, wisdom gained through experience, and beauty that emerges from challenge. Alexandrite symbolizes balance, transformation, and adaptability. Moonstone is associated with intuition, feminine energy, new beginnings, and emotional clarity. A June birthstone gift often pairs the stone choice with the meaning the giver wants to express.
Which June birthstone is most expensive?
Natural alexandrite is by far the most expensive of the three, with fine stones costing more per carat than diamond. Lab-grown alexandrite is significantly more accessible. Natural pearl ranges widely depending on type — South Sea and large Tahitian pearls command the highest prices. Moonstone is the most affordable of the three.
Can a June birthstone be worn in an engagement ring?
Yes, with caveats. Alexandrite is the most engagement-ring-suitable, with a Mohs hardness of 8.5 — comparable to sapphire. Moonstone (6–6.5) is wearable in a ring, ideally in a bezel or protected setting. Pearl (2.5–4.5) is generally not recommended for daily-wear engagement rings, though it works well for occasion-wear pieces. For daily wear, alexandrite is the strongest choice.
What is the difference between alexandrite and moonstone?
Alexandrite is a chrysoberyl variety with strong color change between green and red, hardness 8.5, and is rare and expensive in natural form. Moonstone is a feldspar variety with a floating internal sheen called adularescence, hardness 6 to 6.5, and is far more affordable. Alexandrite suits daily-wear engagement rings; moonstone suits more delicate or occasional wear.
Are pearls the original June birthstone?
Yes. Pearl is the original and most historically established June birthstone, with associations dating back centuries before the modern standardized list. Pearl appears in the 1912 list compiled by the National Association of Jewelers as the primary stone for June. Alexandrite was added later in the mid-20th century; moonstone joined as a third option after that.
How do you care for a moonstone ring?
Moonstone requires gentler care than harder gemstones. Clean with warm water and mild soap using a soft brush. Avoid ultrasonic and steam cleaners. Remove the ring before housework, gardening, exercise, and swimming. Store moonstone separately from harder stones to prevent surface scratches. With careful handling, moonstone retains its blue sheen and clarity for decades. See our full moonstone meaning guide for more.
What is the best gift for a June birthday?
The best gift depends on the recipient. For a classic, sentimental gift, pearl jewelry. For someone who values rarity and dramatic color, alexandrite — especially in lab-grown form. For a recipient drawn to soft, ethereal aesthetics, moonstone. A combination piece featuring two of the three stones captures the unique multi-stone identity of June birthdays in a single object.
