Before being a birthday jewel, the birthstone was a remedy, a protection, an object reserved for a select few. Here is how it has spanned three thousand years to become, today, one of the most powerful drivers of the jewelry industry.
A breastplate, twelve stones
The story begins in the book of Exodus. The high priest Aaron wore a sacred breastplate, the hoshen, set with twelve gemstones arranged in four rows. Each bore the name of one of the twelve tribes of Israel; the stone was not an ornament, it was a priestly attribute, reserved solely for the high priest.
In the 1st century, the historian Flavius Josephus was the first to link these twelve stones to the twelve months of the year and the signs of the zodiac. The idea of one stone per month was born, but for over a millennium, it would remain a theory for scholars rather than a widespread practice.
Rome: the stone as a remedy
In Roman antiquity, the stone was not symbolic: it was medicinal. Pliny the Elder, in his Natural History, and Dioscorides, a Greek physician in the service of Nero, recorded dozens of mineral remedies. Reduced to powder and mixed with wine, honey, or oil, stones were believed to heal: hematite to stop bleeding, green jasper for the stomach and fevers, onyx and agate to soothe pain and promote sleep, malachite against convulsions in young children.
Worn in rings, as amulets, or sewn into clothing, other stones protected rather than cured: amber for children, carnelian for success and longevity, rock crystal to purify a space, turquoise against accidents. These practices crossed all social classes, reaching even the emperors, who wore rings engraved with mystical symbols.
The Middle Ages: the medicine of the stars
In the 11th century, Bishop Marbode of Rennes wrote the Liber lapidum, a lapidary that became the European reference for centuries. These texts, written by clerics from ancient and biblical sources, blended medicine, astrology, and religion: each stone was linked to a sign of the zodiac, believed to govern a specific part of the body. A medieval physician prescribed a stone as they would have prescribed a plant, according to the sign under which the patient was born.
These lapidaries were copied and read in monasteries and royal courts: the gemstone remained a rare object, reserved for the clergy and the nobility. It was only in the 16th century, in Germany and Poland, that the use was simplified: one stone per month, worn as a personal talisman, and the idea began to spread beyond the literate elites.
1912: a list designed to sell
For centuries, the lists varied from one country to another, from one lapidary to another. In 1912, American jewelers gathered in Kansas City made a decision: they established the first standardized list, designed for stones that were easy to find and set, a choice as commercial as it was traditional, which a jewelry historian described bluntly as "nothing more than a sales pitch."
The list has been revised several times since: alexandrite, citrine, pink tourmaline, and zircon in 1952, tanzanite in 2002, spinel in 2016. Far from being set in stone, it continues to evolve along with the jewelry market itself.
Why they are making a comeback today
The birthstone has seen a marked resurgence in recent years, and it is no coincidence. The jewelry industry is observing a shift: customers are looking less for a jewel that shines and more for a jewel that means something. A personal piece, connected to a story, rather than just an accessory.
This desire for personalization has extended well beyond birthdays: stackable rings built up over the years, couple's jewelry combining two stones, children's stones worn by mothers, commemorative pieces. Each new purchase adds a chapter to a personal story, which also explains why these jewels are collected rather than bought just once.
This movement is part of a rapidly growing market: the global jewelry industry is valued at approximately 381.5 billion dollars in 2025, with an expected annual growth of 5.5% until 2033. Online personalization tools, direct-to-consumer brands, and social media, where every piece tells a story that is shared, play a central role in this acceleration. Personalized jewelry is no longer a niche: it has become one of the industry's drivers.

These meanings come from tradition and popular lithotherapy; the Maison shares them as a cultural heritage, without making them a promise.
From rare stone to everyday jewel
For centuries, the birthstone remained reserved for those who could afford a semi-precious or precious stone. It is this idea—a color, a month, a story—that the Éléanore bracelet makes accessible: a colored glass bead, just one, on a delicate stainless steel chain. Twelve shades, one for each month, echoing the tradition without claiming to imitate it.
A jewel designed to be worn every day, to be given for a birth, a birthday, or simply to wear your own month.

Frequently asked questions
Where does the birthstone tradition come from? From the high priest Aaron's breastplate in Exodus, linked to the twelve months by the historian Flavius Josephus in the 1st century. The Romans used them as remedies, medieval lapidaries as astrological medicine, and the custom of one stone per month dates back to the 16th century.
Who wore birthstones originally? First, only the high priest, then the clergy and nobility during the Middle Ages. The custom only became democratized from the 16th century, and only really became mainstream with the standardized list of 1912.
Why are birthstones so fashionable today? Because customers are looking for jewelry that carries meaning as much as style. Stackable rings, couple or family jewelry, commemorative pieces: personalization has become one of the main growth drivers of the global jewelry market.
Has the birthstone list always been the same? No. The official list dates to 1912 and has been revised several times since, most recently in 2016.
Does the Éléanore bracelet use real gemstones? No. Each bead is made of colored glass, an accessible and sustainable interpretation of the traditional shades.
