Those born in May are blessed with the gorgeous green emerald as their traditional birthstone.

The month of May was called Maius in ancient times, likely for the Roman goddess of growth or the Greek goddess of nursing mothers, both named Maia. Ancient Romans also celebrated Floralia in May, a festival honoring the goddess of flowers Flora.

Today, the month of May celebrates mothers, workers, and the rewards of hard work — as they say, “April flowers bring May flowers!”

The May birthstones have even richer history and meanings, which we’ll crack into today as we cover the meanings, properties, and value of emeralds. We’ll also go over some alternative May birthstones!

Historical & Cultural Significance of May Birthstone: Emerald

FIrst, what was the original birthstone for May? It depends on who you ask!

Based on the Biblical origins of birthstones, the Hebrew interpretation for May’s birthstone was agate, while the Arabic interpretation was emerald.

In 1870, Tiffany & Co published a pamphlet of “Gregorian Birthstone Poems,” kicking off modern formalized birthstone lists. The March birthstone poem was:

Who first beholds the light of day

In spring’s sweet, flower month of May

And wears an Emerald all her life

Shall be a loved and a loving wife.

The first modern standardized birthstone list, created by the National Association of Jewellers (now Jewellers of America) in 1912 lists emerald as the May birthstone.

The British 1937 list from the National Association of Goldsmiths, along with the version updated in 2013, lists emerald as the traditional May birthstone and chrysoprase (another chalcedony variety like agate) as an alternative.

Why is emerald associated with May?

The Biblical gemstone lists that inspired birthstones listed emerald (in some translations) fourth, corresponding to the fourth month of the year.

But emeralds also reflect the ideals of May: rebirth, growth, prosperity, and fertility. These interpretations of emerald, among others, go back centuries.

Ancient Emerald History & Mythology

Records of emerald mining date back to ancient Egypt around 1900 to 1500 BC. Egypt remained the primary emerald source until Colombia took over in the 16th century AD.

Ancient names for the stone include:

  • Bwyrq — Egyptians, “to sparkle”

  • Barq — Arabs, “flashing”

  • Baraket — Hebrews, “flashing gem”

Ancient Egyptians considered green sacred, symbolizing agricultural fertility and immortality. Queen Cleopatra famously loved emeralds, adorning herself and her palace with the May birthstone. In fact, in 330 BC, she took exclusive rights to all emeralds mined in Egypt.

Egyptian beliefs about emeralds included the stone granting immortality in the afterlife — often placed in pharaoh’s graves to ensure this — and improving eyesight.

Ancient Greeks and Romans saw emeralds as manifestations of gods and goddesses, particularly as symbols of everlasting love associated with Aphrodite (Venus).

Besides Egyptians, ancient Indians also revered emeralds.

The Sanskrit name for emerald was either marakata, meaning “the green of growing things,” or smarahato, meaning “green.” In fact, the word “emerald” likely derived from an ancient Persian word translated into Latin as smaragdus (meaning “green stone”) before eventually being altered to “emerald.

Ancient Indians referenced emeralds in many religious texts. Written around 1500 to 1200 BC, the oldest Sanskrit and Hindu scripture, The Vedas described emeralds as being lucky and promoting well-being.

In Vedic astrology, emerald or panna is connected to the planet Mercury and believed to boost intellect.

Famous pieces of Indian architecture feature emeralds, like the exquisitely carved “Taj Mahal Emerald” and the carving of goddess Meenakshi created from a single emerald crystal displayed at the Meenakshi Amman Temple.

Lastly, Incas and Aztecs had many legends about emeralds.

One was that the May birthstone formed from an ancient princess’s tears. Another was that the heart of the goddess of good health, Umina, became a huge emerald when she died. They used emeralds for jewelry and religious rituals, often placing the gem in burial mounds.

Emeralds in Royal & Noble Heritage

The association between emeralds and royalty increased over time. European royals and nobles started wearing the May birthstone more during the Renaissance.

You can learn more about these royal emeralds in our guide to 7 famous emeralds.

Some emeralds not mentioned in that guide:

  • Emerald ring given by Pope Innocent III to King Richard the Lionhearted or King John around 1200 AD

  • Holy Grail of Arthurian lore, said to be made of emerald and possess various powers

  • Tiara with emerald centerstone given by Napoleon Bonaparte to Pope Pius VII in 1804

  • Vladimir Tiara, made for Russian Grand Duchess Vladimir and sold to Queen Mary I in 1921, who added her own 15 Cambridge emeralds

  • “Emerald” Buddhas, a sacred 15th century carving of Gautama Buddha made of jadeite and a 2006 version carved from a single 3,600-carat emerald

The May birthstone also has various pop culture references, like:

  • Emerald City featured in the 1900 L. Frank Baum novel The Wonderful Wizard of Oz and the 1939 film adaptation

  • “Emerald Isle” nickname for Ireland

  • Emerald Tablet, a legendary text said to contain universal and alchemic secrets

  • Rockefeller Emerald, the largest flawless emerald and most expensive emerald ever sold at $5.5 million USD

Despite their prestige, emeralds still form in the Earth like any other mineral!

Geological Marvel: The Formation of Emeralds

Emeralds are varieties of beryl, a beryllium aluminum silicate mineral. They have pretty high hardness at 7.5 to 8 on the Mohs scale.

The May birthstone’s color comes from impurities of chromium, vanadium, or both. Part of emerald’s rarity is that beryllium is rarely present in the same area as chromium or vanadium.

In terms of where emeralds are found, Colombia is top-dog, producing 50 to 95 percent of the world’s emeralds. The second top source is Zambia, producing around 20 percent of the world’s gem-quality emeralds.

Colombia and Zambia are known for distinctive emerald colors.

Mesmerizing Green: Understanding Emerald's Color Spectrum

Ever wondered, what is my birthstone color if I was born in May? Green! But the exact shade of green in emeralds varies. Undertones of yellow or blue are common, and tones or saturation levels vary.

Different distinctions between true emeralds and green beryl vary based on the coloring impurities and shade.

There are many types of emeralds, some distinguished by their color and source and other distinguished by optical phenomena:

  • Colombian Emerald: Most prized in deep green color from high chromium and low iron impurities; Prized for rarity and beauty, especially the Gota de Aceite emeralds variety with roiled appearance

  • Zambian Emerald: Bluish-green, darker than Colombian, usually less included than Brazilian

  • Brazilian Emerald: Light green, usually yellowish, less transparent than Colombian, usually included

  • Trapiche Emerald: Naturally formed radial pattern with 6 black spokes resembling a wheel

  • Star Emerald: Displays a multi-rayed “star” of reflected light via asterism

  • Cat’s Eye Emerald: Displays a single ray of reflected light via chatoyancy

The best emerald gemstones are bluish-green with medium-dark tones and heavy saturation, but color is just one factor of this May birthstone’s value.

The 4 Cs: Evaluating Emerald Quality

When grading or certifying the emerald birthstone, gemologists prioritize color, then clarity, followed by cut, carat weight, and treatments.


Most gemologists only classify green beryl as emerald if it has a primary green hue and medium to dark tone. High saturation and purer green colors mean higher value.


These May birthstones are Type 3 colored gemstones, meaning visible inclusions are almost always present. As such, emeralds without inclusions visible to the naked eye are quite valuable.

Many heavily included emeralds appear cloudy. There are many types of emerald inclusions. Often, emeralds are treated to improve their clarity.


The best emeralds are faceted well to maximize color and uniformity, since the stone’s dispersion is rather low.

Many of these May birthstones are faceted with the “emerald cut,” a table cut developed in the 1500s for emeralds to prevent chips or cracks while emphasizing the stone’s color.

Lower-quality emeralds or emeralds with optical effects are cut into cabochons.

Carat Weight

Like other precious gemstones, emerald’s price-per-carat will increase with larger sizes.


Most emeralds are treated via oiling, which improves clarity, durability, and sometimes color by filling in cracks. Lapidarists may use oils, polymers, or epoxy resins for the treatment.

Grading labs will categorize the level of enhancement as none, minor, moderate, or highly enhanced.

Beyond Aesthetics: Emeralds' Symbolism and Mystique

Emeralds are associated with growth, rebirth, and fertility, just like the spring season. The May birthstone meaning also extends to loyalty, friendship, and good luck.


In Greek mythology, emeralds depicted love and wearing them protected couples from being unfaithful. People believed that an emerald would glow brighter when worn by a pure heart. If the shade faltered from its true green then the wearer was thought to be unfaithful.


Similar to faithfulness, emeralds depict the unconditional loyalty between friends. Some friends choose to wear emerald friendship bracelets to symbolize their bond.

Good Luck

Mughal emperor and creator of the Taj Mahal, Shah Jahan, inscribed scriptures into emerald talismans. In the Veda, the Hindu text, emeralds are described as the gem of good luck, capable of improving a person’s wellbeing. In Chinese culture, certain days of the week bring good luck to those wearing emeralds.

As a healing stone, some of emerald’s most touted benefits include improving vision, cleansing the body of illness, and facilitating clairvoyance, especially when used as a third eye chakra stone.

The Ethical Emerald Pursuit

Like the ethical dilemmas surrounding conflict diamonds, many conscious consumers worry about the labor conditions and sustainability of emerald mining.

A major factor of knowing if an emerald was ethically sourced is knowing where it came from, or “transparency of provenance.” That means working with reputable, properly vetted suppliers and industry associations.

Luckily, it’s easier to identify an emerald’s origin than a diamond’s, especially with processes like the Emerald Paternity Test created by Gemfields and Gübelin Gem Lab.

Another possible workaround is opting for synthetic emeralds, which are lab-created with all the same physical and chemical properties of natural emeralds.

Synthetic emeralds lack the hazardous labor conditions of obtaining natural emeralds, with a significantly lower environmental impact.

Plus, synthetic emeralds are much more affordable than natural emeralds!

Speaking of alternatives, are there multiple birthstones for May? According to some sources, yes!

Alternative May Birthstones

The list of May birthstones and crystals doesn’t end at emerald. For one, agate is actually the original May birthstone in many historical interpretations.

Of course, the chalcedony variety chrysoprase is listed as an alternative May birthstone in many lists. Nicknamed the “Stone of Joy,” chrysoprase is a lighter apple green gem perfect for Gemini signs.

Among the mystical birthstones, a list rooted in Tibetan astrology, sapphire is the May birthstone. This corundum variety is another precious gemstone with an array of colors suited to any May-born Taurus sign’s taste.

So, how do you use these May birthstones?

05 mai Pierre de naissance - Émeraude Ceux qui sont nés en mai ont la chance d'avoir l'un des joyaux les plus appréciés comme pierre de naissance: les émeraudes . L'émeraude n'est pas seulement un bijou magnifique, mais un élément adoré de la littérature, des contes de fées et du folklore.

Des amulettes mystiques aux talismans antiques ornant les figures culturelles des divinités grecques aux Incas - les émeraudes sont tissées à travers le tissu scintillant de l'histoire. Il est facile de voir pourquoi tout le monde aime les émeraudes! Après tout, la reine d'Égypte, Cléopâtre, s'est enchâssée dans les émeraudes.

Prêt à tout savoir sur la pierre de naissance de mai? Explorons!

Le joyau le plus vert de tous

Il n'y a pas de contestation sur la qualité magnétisante d'une riche émeraude verte, mais comment obtiennent-elles leur couleur? En tant que membre de la famille des minéraux béryl, la pierre de naissance émeraude est chimiquement composée d'aluminium, d'oxygène, de silicium et de béryllium. La structure cristalline a six côtés qui permettent à la lumière de pénétrer dans la pierre précieuse, de rebondir autour des couches de cristal et de se refléter dans une teinte verte richement saturée.

Pourquoi la lumière reflète-t-elle le vert? La couleur émeraude provient de la présence de chrome dans la structure minérale. La coloration varie du vert clair au vert foncé, selon la quantité de chrome contenue dans la pierre précieuse.

Les plus grandes mines d'émeraude se trouvent en Colombie, mais elles sont également exploitées en Russie, aux États-Unis, en Australie, au Brésil et en Inde.

Les premières représentations d'émeraudes étaient appelées «marakata», qui est le terme sanscrit représentant «le vert des choses en croissance». Plus tard, lorsque les émeraudes ont fait leur chemin dans la haute société, le terme latin officiel, «smaragdus», a été utilisé. Au fil du temps, le terme a évolué pour devenir «émeraude» en anglais.

Les émeraudes ont fait surface pour devenir des artefacts célèbres à travers l'histoire , mais regardons les cultures et les sociétés qui les ont popularisées.

Émeraudes à travers l'histoire

L'histoire de l'extraction d'émeraude remonte à l'ancienne Babylone en 4000 avant JC. Ce n'est qu'en 330 avant JC que la reine d'Egypte a mis un fief sur l'ensemble des mines d'émeraude égyptiennes. C'est vrai, la femme la plus puissante d'Egypte voulait des droits exclusifs sur toutes les émeraudes - et elle l'a obtenu.

Pourquoi les émeraudes ont-elles captivé la reine? Cléopâtre n'était pas la seule à s'intéresser à la pierre richement saturée aux teintes vertes. Les Grecs et les Romains de l'Antiquité considéraient les émeraudes comme une manifestation des dieux et des déesses. De Vénus à Aphrodite, les émeraudes incarnaient la pureté, la fertilité, la beauté et l'amour de la royauté grecque.

Sortant de la mythologie, les émeraudes étaient tout aussi adorées parmi les Aztèques et les Incas. Les mines de Muzo en Colombie placent essentiellement les émeraudes sud-américaines sur la carte mondiale, grâce aux conquistadors espagnols qui ont attaqué les mines.

Finalement, le philosophe Aristote a introduit les émeraudes dans l'Europe traditionnelle et en Occident en écrivant que posséder des émeraudes élevait son statut, sa santé et sa richesse.

Légendes de l'émeraude

Quand vous pensez aux pierres précieuses par excellence, vous pensez naturellement aux diamants, aux rubis, aux saphirs et aux émeraudes, n'est-ce pas? C'est parce que ces quatre pierres précieuses constituent la catégorie des «pierres précieuses».

Beaucoup de gens sont fascinés par ces joyaux scintillants - des pirates à la recherche de trésors à la royauté éblouissante d'émeraudes. Il n'est donc pas surprenant que ce joyau ancien soit inscrit dans la légende et le folklore.

Le plus souvent, les gens pensaient que les émeraudes servaient de portails pour voir l'avenir lorsqu'elles étaient placées sous la langue. Une légende prétend que le port d'émeraudes révélerait si leur amant était fidèle ou faux. D'autres mythes incluent la croyance que les émeraudes amélioreraient la parole et éloigneraient les mauvais esprits.

Ce ne sont là que quelques-unes des légendes entourant les émeraudes. Maintenant, plongeons dans le riche symbolisme de la pierre précieuse.

Signification de la pierre de naissance de mai

Les émeraudes ont de nombreuses significations, mais surtout, elles symbolisent la camaraderie et la loyauté. Le symbolisme des émeraudes ruisselle de ses riches racines mythologiques et religieuses.

Fidélité et loyauté

Dans la mythologie grecque, les émeraudes représentent l'amour et les porter protégeait les couples contre l'infidélité. Les gens croyaient qu'une émeraude brillerait plus brillamment lorsqu'elle était portée par un cœur pur. Si l'ombre perdait de son vrai vert? On pensait que le porteur était infidèle.

Relation amicale

Semblable à la fidélité, les émeraudes représentent la fidélité inconditionnelle entre amis. Certains amis choisissent de porter des bracelets d'amitié émeraude pour symboliser leur lien.

Bonne chance

L'empereur moghol et créateur du Taj Mahal, Shah Jahan, a inscrit des écritures dans des talismans d'émeraude. Dans le Veda, le texte hindou, les émeraudes sont décrites comme le joyau de la chance, capable d'améliorer le bien-être d'une personne. Dans la culture chinoise, certains jours de la semaine portent chance à ceux qui portent des émeraudes.

Propriétés curatives d'émeraude

Les émeraudes sont hautement symboliques, mais saviez-vous que la pierre de naissance de mai a également de puissantes propriétés curatives? C'est vrai - il y a plus que ce que l'on voit avec les émeraudes!

On pense que porter des émeraudes confère une guérison au porteur, c'est pourquoi c'est un excellent cadeau pour l'anniversaire de mai de votre vie!

Beaucoup de gens pensent que regarder les émeraudes peut améliorer la vue. Cette croyance vient de l'ancienne Sumérie, dont les gens croyaient que le port d'une émeraude sur le petit doigt gauche minimisait l'inflammation oculaire. La croyance a été poussée encore plus loin lorsque les gens ont écrasé des émeraudes en une poudre utilisée pour hydrater les yeux.

Les émeraudes sont une pierre de nettoyage vitale utilisée pour débarrasser le corps des impuretés et des infections. Se connectant directement à plusieurs méridiens du corps, on dit que les émeraudes minimisent les maux physiques tels que les maux de tête, l'hypertension artérielle, la fièvre et l'asthme.

La pierre de naissance de mai a également des propriétés curatives métaphysiques. Les émeraudes aident à conjurer l'énergie négative, invitent à stabiliser l'énergie, l'harmonie et l'équilibre.

Avec un symbolisme et des pouvoirs de guérison aussi riches, il n'est pas étonnant que tout le monde aime les émeraudes! Comme vous vous en doutez, une pierre précieuse aussi fascinante fait de beaux bijoux.

Bijoux de pierre de naissance de mai

Parce que les émeraudes ont des propriétés curatives, de nombreuses personnes choisissent de les porter en bijoux. Il est facile de voir pourquoi Cléopâtre, Elizabeth Taylor, la princesse Diana et bien d'autres personnages notables affichaient des émeraudes scintillantes!

La pierre de naissance de mai embellit magnifiquement les colliers, les boucles d'oreilles et les bagues. Un style populaire est de porter une bague émeraude taille émeraude! Non seulement le port d'émeraudes résume les traditions anciennes, le symbolisme religieux et la signification culturelle, mais ils sont tout simplement magnifiques.
