History and Lore of Birthstones
The tradition of associating gemstones with specific months of the year dates back thousands of years. One of the earliest known references to birthstones appears in the ancient Hebrew Breastplate of the High Priest, described in the Old Testament (Exodus 28:17-20). This sacred garment, worn by the High Priest of the Israelites, contained twelve stones, each representing one of the twelve tribes of Israel. While the exact identities of these stones remain a subject of debate among scholars, they laid the foundation for the later association of gemstones with months and zodiac signs.
The first documented list of birthstones by month emerged in the 4th century AD, found in the writings of St. Isidore of Seville. His compilation, known as the "Etymologiae," listed twelve gemstones with their corresponding months and symbolic meanings. This early list included stones like emerald, ruby, and sapphire, many of which are still recognized as modern birthstones.
During the Middle Ages, the practice of assigning gemstones to months became more widespread in Europe. The belief that these stones held mystical properties—such as the power to bring good fortune, protection, or healing—gained popularity. This period saw the creation of talismans and rings set with birthstones, often used for both decorative and protective purposes.
By the 19th century, the modern birthstone tradition began to take shape in the United States. Jewelers and marketers played a significant role in promoting the idea that each month had its own unique gemstone, which could be worn as a symbol of one's birth month. This commercialization helped solidify the modern birthstone chart, which was first formally established in 1912 by the American National Association of Jewelers (now the Jewelers of America). This organization created a standardized list of birthstones that has since been updated to include new discoveries and variations.
Modern vs. Traditional Birthstones
While the modern birthstone chart is widely recognized and used today, it is important to understand that there are also traditional birthstones for each month. These traditional stones differ from the modern ones and were used in earlier centuries, often based on regional customs and historical practices.
The distinction between modern and traditional birthstones is particularly evident in months that have multiple gemstones. For example, while June's modern birthstones are alexandrite and pearl, its traditional birthstone was also pearl. Similarly, October's traditional birthstone was opal, while the modern version includes tourmaline. In November, topaz was the traditional birthstone, while modern options include citrine and topaz.
The modern birthstone chart, as established in the 20th century, reflects changes in gemology, mining, and consumer preferences. The introduction of new gemstones, such as alexandrite in June and tanzanite in December, demonstrates how the list has evolved to include more recently discovered or newly marketed stones. These additions often cater to the availability and affordability of gemstones, making them more accessible to a wider audience.
Despite these changes, many traditional birthstones remain popular today. For example, garnet (January), amethyst (February), and diamond (April) have remained consistent in both modern and traditional charts. This continuity underscores the enduring appeal of certain gemstones and their deep-rooted associations with specific months.
The choice between modern and traditional birthstones is often a matter of personal preference. Some individuals prefer to follow the modern chart, while others may choose traditional stones for their historical significance or sentimental value. Jewelers today often offer both options, allowing customers to select the gemstone that resonates most with them.

Gemological Properties of Birthstones
Each birthstone has unique gemological properties that contribute to its beauty, value, and significance. These properties include hardness, color, chemical composition, and refractive index, among others. Understanding these characteristics can help gemstone enthusiasts and jewelry buyers make informed decisions about the care and use of these precious stones.
Hardness on the Mohs Scale
The hardness of a gemstone is measured on the Mohs scale, which ranges from 1 (softest) to 10 (hardest). This scale helps determine how resistant a stone is to scratches and wear. For example, diamond, the birthstone for April, has a hardness of 10 and is the hardest known natural substance. In contrast, pearls, the traditional birthstone for June, have a much lower hardness of around 2.5 to 4.5, making them more delicate and prone to damage.
Understanding the hardness of a birthstone is important for selecting appropriate settings and care practices. Harder stones like ruby (July) and sapphire (September), which have a hardness of 9, are more durable and suitable for everyday wear, while softer stones like opal (October) and pearls (June) require more careful handling and storage.
Color and Chemical Composition
The color of a gemstone is one of its most defining characteristics and is often what makes it desirable as a birthstone. The color is determined by the chemical composition and structure of the stone. For example, emerald (May) gets its green color from the presence of chromium or vanadium, while amethyst (February) owes its purple hue to iron impurities in quartz.
Some birthstones, such as garnet (January), come in a variety of colors, including red, green, orange, and even blue. This diversity makes garnet a versatile and unique birthstone. Other stones, like diamond (April), are known for their colorless or near-colorless appearance, though they can also occur in a range of colors due to trace elements in their crystal structure.
Refractive Index and Brilliance
The refractive index of a gemstone determines how light is bent as it passes through the stone, affecting its brilliance and sparkle. Diamonds, for example, have a high refractive index of 2.42, which contributes to their exceptional brilliance and fire. Opals, on the other hand, have a lower refractive index and are known for their play of colors rather than their brilliance.
Understanding the refractive index can help in identifying and evaluating gemstones. It is also an important factor in cutting and polishing, as the way a stone is cut can enhance or diminish its refractive properties.
Rarity and Market Value
Rarity plays a significant role in the value of a birthstone. Some gemstones, such as alexandrite (June) and tanzanite (December), are considered rare and command higher prices in the market. Alexandrite, for instance, is a rare color-changing gemstone that was only discovered in the 19th century. Tanzanite, found only in Tanzania, is another rare gemstone that has gained popularity in recent decades.
Other birthstones, such as garnet (January) and amethyst (February), are more abundant and therefore more affordable. However, certain varieties of these stones, such as tsavorite garnet or demantoid garnet, can be more valuable due to their rarity and unique characteristics.
Cultural and Metaphysical Beliefs
Throughout history, birthstones have been attributed with various cultural and metaphysical beliefs. These beliefs often reflect the values, traditions, and superstitions of different societies. While some of these beliefs have persisted into modern times, others have faded as scientific understanding has advanced.
Protection and Healing
One of the most common beliefs associated with birthstones is their protective and healing properties. Many cultures believed that wearing a birthstone could shield the wearer from harm and illness. For example, in medieval Europe, it was believed that amethyst could prevent intoxication and was often worn by those seeking sobriety. Similarly, opal was thought to bring good luck and to enhance one's intuition and creativity.
In ancient China, jade was considered a powerful protective stone and was often carved into amulets for use in rituals and ceremonies. While jade is not a traditional birthstone in the Western tradition, its significance in other cultures highlights the universal appeal of gemstones as symbols of protection and well-being.
Symbolism and Meaning
Each birthstone carries its own symbolic meaning, often linked to the qualities and virtues associated with the month in which a person is born. For example, garnet (January) symbolizes constancy and loyalty, while ruby (July) represents passion and vitality. These symbolic meanings have been passed down through generations and continue to influence the way people choose and wear birthstone jewelry.
In some cultures, birthstones are also associated with zodiac signs and planetary influences. For example, in Vedic astrology, gemstones are used to balance the energies of the planets and to enhance one's fortune. This practice has influenced the way birthstones are used in jewelry and other symbolic objects in various parts of the world.
Spiritual and Emotional Significance
Many birthstones are also believed to have spiritual and emotional significance. For example, amethyst (February) is associated with spiritual growth and inner strength, while opal (October) is believed to enhance creativity and inspiration. These beliefs often guide the way people use and wear birthstones, whether for personal reflection, meditation, or as a source of comfort and support.
In modern times, the spiritual and emotional significance of birthstones continues to be recognized, particularly in the fields of crystal healing and energy work. While these practices are not scientifically validated, they remain popular among those who seek alternative approaches to well-being and personal development.
Care and Maintenance of Birthstones
Proper care and maintenance are essential for preserving the beauty and value of birthstones. The specific care requirements for each gemstone depend on its hardness, chemical composition, and other properties. Here are some general guidelines for caring for different types of birthstones:
Hardness and Cleaning
Harder gemstones, such as diamond (April), ruby (July), and sapphire (September), are more resistant to scratches and can be cleaned with standard jewelry cleaners. However, softer gemstones, such as opal (October) and pearls (June), require more delicate care. Opal, for example, is sensitive to dryness and should be stored in a humid environment to prevent cracking. Pearls, which are organic gemstones, can be damaged by harsh chemicals and should be cleaned gently with a soft cloth.
Storage and Handling
Proper storage is important for protecting birthstones from damage. Harder gemstones can be stored together, but softer stones should be kept separate to avoid scratches. It is also important to store gemstones in a cool, dry place to prevent damage from heat, moisture, or extreme temperature changes.
When handling gemstones, it is best to use a soft cloth or gloves to avoid leaving fingerprints or oils on the surface. This is especially important for porous stones like opal and pearls, which can absorb oils and become dull over time.
Professional Cleaning and Inspection
For valuable or delicate gemstones, it is recommended to have them professionally cleaned and inspected periodically. Jewelers can provide specialized cleaning services that are safe for different types of gemstones and can also check for loose settings, wear, and other potential issues.
Regular inspections can also help identify any changes in the appearance or condition of a gemstone, such as discoloration, cracks, or fading. Early detection of these issues can help prevent further damage and ensure the long-term beauty of the stone.
