The History of Birthstones: From Ancient Times to Today

A complete guide to how birthstones began, evolved, and became the jewelry tradition we know now

Birthstones feel timeless. Most people grow up knowing their month’s gemstone — maybe as a childhood bracelet, a pendant gifted on a birthday, or a ring passed down in a family. But the story behind birthstones goes far deeper than jewelry trends. It stretches across religious texts, trade routes, the rise of mineralogy, and changing cultural values.

Today we are used to the idea of “one birthstone per month,” but that neat list is the result of centuries of reinterpretation. The first widely adopted standard list in the United States dates only to 1912, and it has been revised several times since. Before that, birthstones were more fluid and based heavily on availability, local beliefs, and astrology.

This article walks through the entire lineage — from ancient roots to modern retail — so you can understand not just what each birthstone is, but how the tradition formed. If you are new to the topic, our beginner’s guide What Are Birthstones? covers the basics first.

A note on how we write about this: history in this article is separated from belief. Dates, lists and gemstone properties are presented as fact where sources support them; symbolism and metaphysical ideas are described as traditions and beliefs, not as proven effects, and nothing here is medical or financial advice.

Birthstone History at a Glance

For readers who want the short version, here is how the main milestones line up. Some early dates are scholarly estimates, and historians disagree on a few of them.

1st century	Josephus connects the twelve stones to months and zodiac signs	Planted the “twelve stones, twelve months” idea
Around the 5th century	St. Jerome repeats the Josephus association	Carried the idea into Christian scholarship
1500s–1700s	Wearing a single stone for your birth month emerges	Gemologists and historians disagree on where: GIA points to Germany in the 1560s, while George F. Kunz placed it in 18th-century Poland
1912	National Association of Jewelers adopts a standard U.S. list	First widely used modern list, built for clarity in retail
1937	Britain’s National Association of Goldsmiths issues its own list	Shows that lists differ by country

2002	Tanzanite added for December	The American Gem Trade Association adds a stone discovered in the 1960s
2016	Spinel added for August	AGTA and Jewelers of America add it alongside peridot
2021	Japan revises its list	Ten stones added, bringing Japan’s list to 29

1. Ancient Beginnings: Where the Birthstone Concept Started

The earliest seeds of the birthstone idea come from sacred texts, symbolic objects, and cultural practices dating back more than 2,000 years.

The Breastplate of the High Priest (Biblical Origins)

One of the first recorded references to “assigned stones” appears in the Book of Exodus. A ceremonial breastplate worn by the High Priest of Israel was described as being set with twelve different gemstones, arranged in four rows of three.

Each stone represented one of the twelve tribes of Israel. The object became foundational in how later generations connected gemstones to identity, meaning, and order.

The twelve stones named in the traditional English text are roughly:

• Sardius
• Topaz
• Carbuncle
• Emerald
• Sapphire
• Diamond
• Ligure
• Agate
• Amethyst
• Beryl
• Onyx
• Jasper

But here is where things get complicated. Gemstone terminology thousands of years ago was not the same as today. Words like “sapphire,” “topaz,” and “carbuncle” often referred to general colors or looks rather than specific minerals — what ancient writers called sapphire, for instance, may well have been what we now call lapis lazuli. Translators later tried to pair the names with modern stones, which created confusion that still affects gemstone traditions.

So while the breastplate is a key symbolic starting point, it is not the same as the modern birthstone system. It simply inspired the broader idea that twelve stones could represent twelve groups.

The Twelve Months and Twelve Stones Connection

The first-century historian Josephus is generally credited with linking the breastplate stones to the twelve months of the year and the twelve signs of the zodiac. St. Jerome, writing several centuries later, echoed that association, which helped carry it into medieval Europe. In later centuries, religious writers also tied individual stones to the apostles and to the foundation stones of the New Jerusalem described in the Book of Revelation.

Not everyone agreed on the pairings — even Josephus is reported to have given more than one list — and interpretations varied by region and century. But the concept of “twelve stones = twelve time periods” had taken root. By the early centuries A.D., it became common for people to wear stones believed to be connected to their birth month or zodiac sign for protection, luck, or symbolic meaning. For more on the astrological side, see Zodiac Birthstones vs. Monthly Birthstones.

Gemstones as Talismans in Ancient Civilizations

Across ancient cultures, gemstones were worn as ornaments and as amulets. Historical records describe a range of beliefs: protection, good fortune, health, and spiritual alignment. These were beliefs of their time and are not supported by scientific evidence.

Babylonians are often credited with associating stones with gods and constellations.
Greeks and Romans linked stones to planetary rulers and gods.
Hindu astrological tradition developed the Navaratna — nine gems associated with the nine celestial bodies of Vedic astrology.
Egyptians used stones like lapis lazuli, turquoise, and carnelian in symbolic jewelry and funerary objects.

While these systems were not “birthstones” in the modern sense, the idea that stones carry meaning — and that certain stones match certain people — became widely accepted. That groundwork eventually led to the more structured systems we know today.

2. Medieval and Renaissance Periods: Birthstones Become Personal

By the Middle Ages, traditions across Europe, the Middle East, and Asia began merging. Trade routes brought greater gemstone variety, and cultural exchange shaped beliefs about which stones aligned with which months.

Wearing All Twelve vs. Wearing Just One

Early interpretations suggested people should keep all twelve stones and wear the one for the current month, rotating them through the year. The idea of wearing only your own birth-month stone came later, and scholars disagree about when and where it began.

Supply issues made collecting twelve stones impractical for almost everyone. Not everyone had access to high-value stones like ruby or emerald — and not every town had a skilled gem cutter. So jewelers and religious scholars began pairing specific stones with each month, creating more accessible frameworks.

Early European Birthstone Lists

Medieval birthstone charts were inconsistent. Records show multiple systems circulating at the same time, often influenced by:

• local trade (which stones were actually available)
• religious symbolism
• zodiac traditions
• linguistic interpretation and translation errors

A “birthstone list” in one region could look very different from a list in another. Still, the concept was now part of European life. Birthstones appeared in church objects, nobility jewelry, talismans, engraved rings, and dowry items. As lapidary knowledge improved, stones were identified more accurately, which helped stabilize names.

3. 18th–19th Century: Science and Trade Reshape the Lists

The modern birthstone tradition took shape between the 1700s and early 1900s, a period of gemstone discovery, trade, and classification.

Poland and the Single Birthstone

The gemologist George Frederick Kunz, in his early-1900s writing on gems, placed the beginning of the custom of wearing a single stone for your birth month in 18th-century Poland. Other researchers, including the Gemological Institute of America, trace a month-by-month custom to 16th-century Germany instead. The origin of the “one month, one stone” custom is therefore debated, and it is safest to say it emerged in central Europe before spreading to Britain and the United States.

Scientific Advancements Change Everything

During the 18th and 19th centuries:

• mineralogy became a formal science
• stones received clearer classifications based on chemistry and crystal structure
• gemology began to differentiate species and varieties

For the first time, people could reliably tell apart stones that look alike, such as:

• ruby from red spinel (the famous “Black Prince’s Ruby” in Britain’s Imperial State Crown is a red spinel)
• sapphire from other blue stones
• emerald from green glass and look-alike green minerals

This meant birthstone lists could increasingly be built on true mineral identities instead of color guesses. If you are curious how color itself works in gemstones, our guide to the science behind gemstone colors explains the chemistry.

Trade Routes Expand Gemstone Availability

New and rediscovered sources widened what jewelers could sell:

• Brazil (topaz, tourmaline, aquamarine)
• Sri Lanka (sapphire, spinel)
• Burma, now Myanmar (ruby, spinel)
• Africa (garnet varieties, aquamarine, and later tanzanite)

Gemstones that had once been reserved for royalty became more accessible. With more stones in the jewelry market, demand for a standardized birthstone list grew.

4. The Modern Birthstone List Is Born (1912)

In 1912, the National Association of Jewelers (a predecessor of today’s Jewelers of America) met in Kansas City and adopted the first standardized modern birthstone list in the United States. It is the foundation of the list most people reference today, though it differs from the current one in several months.

The 1912 list assigned, in broad terms (a few months also carried alternates):

• January — Garnet
• February — Amethyst
• March — Bloodstone (aquamarine as an alternative)
• April — Diamond
• May — Emerald
• June — Pearl (moonstone as an alternative)
• July — Ruby
• August — Sardonyx
• September — Sapphire
• October — Opal
• November — Topaz
• December — Turquoise (lapis lazuli as an alternative)

The goal was simplicity, consistency, and commercial clarity. Jewelers wanted a framework shoppers could easily understand and manufacturers could market. Some historians have pointed out that the 1912 list was as much a retail tool as a heritage tradition, which is a useful reminder that no single list is “the” ancient one.

5. Major 20th–21st Century Additions and Revisions

The birthstone list you see today is not identical to the 1912 version. Several updates reflected consumer preference, new discoveries, and the availability of affordable alternatives. Here are the biggest changes.

1937 — Britain Publishes Its Own List

The National Association of Goldsmiths of Great Britain issued a standardized list of its own, which is part of why British and American lists still differ in places.

1952 — The U.S. List Is Revised

The Jewelry Industry Council of America updated the American list, adding alternatives and swapping some stones:

• Alexandrite added for June
• Pink tourmaline added for October
• Citrine added for November
• Zircon added for December
• Aquamarine became the leading March stone, with bloodstone as the alternative

This modernized the list and gave buyers more color and price options in the months with a single, expensive or hard-to-find stone.

2002 — Tanzanite Added for December

Tanzanite, first discovered in northern Tanzania in the 1960s, gained rapid international popularity. In 2002 the American Gem Trade Association added it as a December birthstone — a rare case of a new gemstone entering the birthstone world. Tanzanite is a blue-violet variety of the mineral zoisite and is commonly heat-treated; it also has perfect cleavage, so it needs more care in rings than its popularity suggests.

2016 — Spinel Added for August

Spinel, historically mistaken for ruby, earned recognition for its own identity. In 2016, Jewelers of America and the American Gem Trade Association announced it as an additional August birthstone alongside peridot. Spinel is a hard, durable gem that comes in red, pink, blue, and other colors.

6. Cultural and International Variations

While the U.S. birthstone list is the most widely used, it is not the only one. Different traditions exist in Britain, Japan, India, Poland, and Scandinavia, among others.

British Birthstones

Britain’s 1937 list and older traditional lists differ from the American one in several months; the British trade has historically been more conservative about adding new stones.

Hindu Birthstones

Traditionally linked to Vedic astrology and the Navaratna system, which pairs nine gems with nine celestial bodies rather than twelve months.

Japanese Birthstones

Japan’s list was revised in 2021 — the first major update in decades — with ten stones added, for a total of 29. The new list reflects modern gemstone popularity and local tastes.

These variations show that birthstones are not a universal rule — they are a cultural tradition that adapts to time, geography, and the jewelry trade. Even within the United States, trade bodies differ: for example, the American Gem Society does not list moonstone for June, while Jewelers of America and AGTA do.

7. Why Birthstones Matter Today

Even though the original concept began with religious symbolism and zodiac alignments, birthstones have taken on new roles in modern life.

Identity and Personal Meaning

Birthstones work like a miniature signature — a way to say, “This is mine. This represents me.” People connect with color, symbolism, history, and emotional associations, and some also with metaphysical meaning.

Gifting Traditions

Birthstone jewelry is one of the most popular gift categories because it feels personal without being overly specific. Common birthstone gifts include:

• pendants
• stackable rings
• charm bracelets
• mother’s rings
• minimalist necklaces
• engagement rings (especially sapphire, emerald, and ruby)

Beliefs and Modern Crystal Traditions

Birthstones were not originally tied to modern crystal-healing practice, but today’s crystal traditions often overlap with birthstone symbolism. In those practices, people associate stones with ideas such as grounding, calmness, good luck, clarity, love, and emotional balance. These are personal and cultural beliefs. They are not supported by scientific evidence and are not a substitute for medical care.

Fashion and Color Trends

Birthstones have also become tied to color palettes and seasonal aesthetics — sapphire blue for autumn, emerald green for spring, ruby red for summer, and amethyst purple for winter are common styling pairings in jewelry marketing. Birthstones give designers a built-in storytelling element.

8. Monthly Birthstones: A Modern Overview with Durability Notes

Here is the most widely used contemporary U.S. system, based on the Jewelers of America and AGTA lists as they stand after the 2002 and 2016 additions. The symbolism column reflects traditional associations, not scientific properties. The hardness column is the Mohs scale, which measures scratch resistance only — it does not tell you how well a stone resists chipping or cracking. Always check for cleavage and treatments before choosing a stone for everyday wear.

Month	Stone(s)	Mohs hardness	Traditional symbolism	Daily-wear note
January	Garnet	6.5–7.5 (varies by type)	Protection, loyalty	Good for most jewelry
February	Amethyst	7	Calm, clarity	Can fade with prolonged strong light or heat
March	Aquamarine; bloodstone	7.5–8; about 6.5–7	Peace, courage	Aquamarine suits rings well
April	Diamond	10	Strength, enduring love	Hardest natural gem, but can still chip along cleavage
May	Emerald	7.5–8	Growth, new beginnings	Fractures are common and oil treatment is routine, so protective settings help
June	Pearl; moonstone; alexandrite	2.5–4.5; 6–6.5; 8.5	Intuition, transformation	Pearl and moonstone suit earrings and pendants better than daily rings
July	Ruby	9	Passion, vitality	Very durable
August	Peridot; spinel; sardonyx	6.5–7; 8; about 6.5–7	Confidence, renewal	Spinel is durable; peridot is better for occasional wear
September	Sapphire	9	Wisdom, loyalty	Very durable
October	Opal; tourmaline	5.5–6.5; 7–7.5	Creativity, expression	Opal is delicate and can crack with sudden temperature change
November	Topaz; citrine	8; 7	Warmth, abundance	Topaz has cleavage; much citrine is heat-treated amethyst
December	Turquoise; tanzanite; zircon; blue topaz	5–6; 6.5–7; 6.5–7.5; 8	Clarity, communication	Tanzanite and turquoise are best for protected settings

Lists vary: some retailers use blue topaz for December, and the American Gem Society’s list differs slightly from the trade-association list above. If you are buying for a specific person, check which list they grew up with. For detailed meanings, month by month, start from our complete guide by month.

9. What the History Means When You Buy Birthstone Jewelry

Knowing that lists evolved is practical, not just interesting. A few takeaways:

• You have real choices. Because lists include alternates, you can choose a more durable or affordable stone — for example spinel instead of peridot for a daily ring, or citrine instead of topaz — without breaking tradition.
• Check the treatment. Many birthstones are routinely treated: sapphire and ruby are often heat-treated, emerald is usually oiled, and blue topaz is typically irradiated and heated. Treatment is normal when disclosed, but it affects price and care. Our guide to natural vs. lab-grown birthstones explains the difference between natural, lab-grown, and imitation stones.
• Match the stone to the piece. Soft stones like pearl, opal, and turquoise are better in earrings and pendants than in a ring worn every day.
• Mind the cut. The way a stone is shaped changes how it looks and how well it is protected; see gemstone shapes and cuts explained.
• Safety for children. Small stones and clasps can be a choking hazard for young children, so choose age-appropriate pieces for little ones.
