The birthstone chart is a cornerstone of jewelry culture, blending historical tradition with contemporary design. This visual guide assigns specific gemstones to each month of the year, offering not only aesthetic appeal but also symbolic and cultural significance. For gemstone enthusiasts, jewelry buyers, and students of gemology, the birthstone chart provides a valuable reference for understanding the meaning and value behind these precious and semi-precious stones. The chart has evolved over time, starting from ancient traditions to modern standardized lists, and now includes multiple options for many months, allowing for personalization and variety in jewelry design.
The history of birthstones can be traced back to the biblical Book of Exodus, which describes the Breastplate of Aaron, a sacred artifact worn by the high priest of the Israelites. This breastplate was adorned with twelve gemstones that symbolized the twelve tribes of Israel. This ancient practice laid the foundation for the connection between gemstones and specific groups, which later evolved into an association with birth months. Over centuries, this concept spread across cultures, with various civilizations attributing different stones to specific times of the year based on astrological, religious, or seasonal beliefs.
In the United States, the birthstone chart was standardized in the early 20th century. The modern list, which is widely recognized today, was officially adopted by the American National Retail Jewelers Association (now known as Jewelers of America) in 1912. This list was created to provide a consistent reference for the jewelry industry and consumers. However, the chart has not remained static; it has been updated over time to include new gemstones and alternative options. For instance, in 2016, Spinel was added as an alternative birthstone for August, reflecting the dynamic nature of this tradition and the discovery of new gem sources.
Understanding the traditional and modern birthstone charts is essential for anyone interested in gemstones. The traditional chart features time-honored gems that have been associated with each month for centuries, while the modern chart includes updates and alternatives officially recognized by jewelry associations. Some months, like June and December, now offer three or more options, providing a wider range of choices for jewelry design and personal preference. This evolution makes the birthstone chart more inclusive and versatile, allowing individuals to select stones that resonate with their personal style, cultural background, or metaphysical beliefs.
The symbolic meanings attached to each birthstone add another layer of depth to their use. These meanings often derive from historical lore, cultural traditions, or the perceived properties of the gemstone itself. For example, Garnet, the birthstone for January, symbolizes friendship and protection, while Amethyst for February represents peace and tranquility. These associations are not merely decorative; they carry emotional and spiritual significance, making birthstone jewelry a thoughtful gift for birthdays, anniversaries, or other milestones.
In addition to their symbolic value, birthstones possess distinct gemological properties that influence their durability, appearance, and care. The hardness of a gemstone, measured on the Mohs scale, is a critical factor in its suitability for different types of jewelry. For instance, Diamond, with a hardness of 10, is ideal for rings that endure daily wear, while Pearl, with a hardness of 2.5 to 4.5, requires more delicate handling. Understanding these properties helps consumers make informed decisions about jewelry selection and maintenance.
The birthstone chart also serves as an educational resource. Teachers, students, and enthusiasts use it to learn about mineralogy, cultural traditions, and the historical significance of each stone. It bridges the gap between science and art, offering insights into how geological processes create beautiful gems and how human cultures have imbued them with meaning. For jewelers and designers, the chart is a practical tool for creating custom pieces, whether crafting engagement rings, family jewelry, or personalized accessories.
Color coordination is another practical application of the birthstone chart. By knowing the typical colors associated with each month, individuals can coordinate jewelry with outfits and occasions. For example, the soft blue of Aquamarine for March complements spring wardrobes, while the vibrant green of Emerald for May pairs well with summer ensembles. This aspect makes the chart useful not only for gift-giving but also for personal styling.
The official birthstone chart is more than just a list of gemstones; it is a reflection of history, culture, and personal identity. From its ancient origins to its modern interpretation, it continues to play a significant role in the world of gemology and personal adornment. As we explore the chart in detail, we will examine the traditional and modern options for each month, their historical contexts, gemological properties, and symbolic meanings. This comprehensive guide aims to provide a thorough understanding of the birthstone chart, empowering readers to appreciate and utilize this timeless tradition.
Historical Foundations: From Ancient Lore to Modern Standardization
The concept of assigning gemstones to birth months has ancient origins, deeply rooted in religious and cultural traditions. One of the earliest recorded references comes from the biblical Book of Exodus, which describes the Breastplate of Aaron. This sacred artifact, worn by the high priest of the Israelites, was adorned with twelve gemstones that symbolized the twelve tribes of Israel. Each stone was believed to hold specific powers and meanings, establishing a precedent for the association between gemstones and specific groups or individuals. This practice laid the groundwork for later traditions that linked gemstones to birth months, as seen in various cultures around the world.
Over time, the idea of birthstones spread across different civilizations. In ancient Rome and Greece, for example, gemstones were often associated with astrological signs and were believed to influence the wearer's life and fortune. The Romans, in particular, placed great importance on gemstones, using them not only for adornment but also for their perceived protective and healing properties. This cultural diffusion helped solidify the connection between gemstones and personal identity, which eventually evolved into the modern birthstone tradition.
The modern birthstone chart, as recognized today, was standardized in the United States in the early 20th century. In 1912, the American National Retail Jewelers Association (now Jewelers of America) adopted an official list of birthstones. This list was created to provide consistency for the jewelry industry and to offer a clear reference for consumers. The decision was influenced by a desire to modernize the tradition and make it more accessible to a broader audience. The 1912 list included gemstones that were commercially available and held significant value in the market, ensuring that the chart was both practical and meaningful.
Since its initial adoption, the birthstone chart has undergone several updates to reflect changes in the gemstone market and cultural preferences. For instance, in 2016, Spinel was added as an alternative birthstone for August. This update was driven by the increasing availability and popularity of Spinel, which had been historically overlooked despite its beauty and durability. Such revisions demonstrate that the birthstone chart is not a static relic but a living document that evolves with new discoveries and trends in gemology.
The traditional birthstone chart, which predates the modern list, features gems that have been associated with each month for centuries. This chart is often considered the "time-honored" list and includes stones like Bloodstone for March, Sardonyx for August, and Topaz for November. While the modern chart has replaced some of these with more commercially popular options, the traditional stones still hold cultural and historical significance. Many people choose traditional stones for their connection to heritage and ancient beliefs, adding a layer of depth to their jewelry choices.
The coexistence of traditional and modern charts highlights the dynamic nature of the birthstone tradition. It allows individuals to select stones based on personal preference, whether they value historical authenticity or contemporary relevance. For example, someone born in August might choose the modern Peridot for its vibrant green color or opt for the traditional Sardonyx for its historical ties. This flexibility makes the birthstone chart a versatile tool for personal expression and cultural exploration.
Understanding the historical journey of the birthstone chart enriches our appreciation of these gems. It connects us to ancient practices while allowing for modern interpretations. As we delve into the specific stones for each month, we will explore their individual histories, properties, and meanings, building a comprehensive picture of the birthstone tradition.
January: Garnet
Garnet is the traditional and modern birthstone for January. It is a group of silicate minerals that share a similar crystal structure but vary in chemical composition, resulting in a wide range of colors. However, the most recognized color for Garnet is a deep, rich red, which has made it a symbol of passion and energy. Historically, Garnet has been valued for centuries, with evidence of its use in ancient Egypt, Greece, and Rome. It was often worn as a protective talisman, believed to ward off negative energies and ensure safe travels.
In terms of gemological properties, Garnet has a hardness of 6.5 to 7.5 on the Mohs scale, making it suitable for various types of jewelry, including rings, earrings, and pendants.

These variations contribute to the diversity of colors found in Garnet, including orange, yellow, green, and even brown, though red remains the most popular for January birthstones.
Symbolically, Garnet is associated with friendship, trust, and protection. It is believed to bring stability and strength to relationships, making it a meaningful gift for loved ones. In metaphysical beliefs, Garnet is thought to inspire love and devotion, and to enhance vitality and perseverance. These symbolic meanings add emotional value to Garnet jewelry, making it a cherished possession for those born in January.
When caring for Garnet jewelry, it is important to clean it gently with warm, soapy water and a soft brush. Avoid harsh chemicals or ultrasonic cleaners, which could damage the stone. Due to its hardness, Garnet is relatively resilient, but it should be stored separately from other jewelry to prevent scratching. For those who appreciate variety, Garnet offers a spectrum of options beyond the classic red, allowing for personalized jewelry designs that reflect individual taste.
February: Amethyst
Amethyst is the birthstone for February, known for its captivating purple hues ranging from light lavender to deep violet. This gemstone is a variety of quartz, composed of silicon dioxide with traces of iron that give it its distinctive color. Historically, Amethyst has been prized by royalty and religious figures for its beauty and perceived properties.

Major sources of Amethyst include Brazil, Uruguay, and Zambia, with each region producing stones of varying color intensity and quality.
Symbolically, Amethyst is associated with peace, protection, and tranquility. It is believed to promote emotional balance and spiritual awareness, making it a popular stone for meditation and healing practices. In metaphysical traditions, Amethyst is thought to alleviate stress and anxiety, and to enhance intuition. These beliefs make Amethyst jewelry not only a beautiful accessory but also a tool for personal well-being.
Caring for Amethyst is straightforward due to its hardness. It can be cleaned with mild soap and water, and should be protected from prolonged exposure to sunlight, which can cause fading. Amethyst jewelry should be stored in a soft cloth to prevent scratches. For February-born individuals, Amethyst offers a regal and serene option that complements both casual and formal attire.
March: Aquamarine
Aquamarine, the primary birthstone for March, derives its name from the Latin words for "water" and "sea," reflecting its soothing blue to blue-green color. This gemstone is a variety of beryl, sharing a family with emerald and morganite. Historically, Aquamarine has been associated with sailors, who believed it offered protection against storms and ensured safe voyages. Its connection to the sea is also linked to ancient Roman and Greek myths, where it was thought to be the treasure of mermaids.
Aquamarine is composed of beryllium aluminum silicate with traces of iron that impart its color. It has a hardness of 7.5 to 8 on the Mohs scale, making it one of the more durable gemstones suitable for rings and other jewelry that experiences regular wear. The stone is typically found in large crystals, allowing for the creation of impressive faceted gems or carvings. Major sources include Brazil, Nigeria, Madagascar, and Pakistan, with Brazilian aquamarines often exhibiting the most prized deep blue hues.

To care for Aquamarine jewelry, clean it with warm, soapy water and a soft brush. Avoid sudden temperature changes and harsh chemicals, which could damage the stone. Due to its hardness, it is relatively resistant to scratching but should be stored separately from harder gems like diamond. Aquamarine's cool blue tones make it a versatile choice for jewelry, pairing well with both silver and gold settings.
April: Diamond
Diamond is the birthstone for April, renowned for its exceptional brilliance and durability. As the hardest known natural material, diamond scores a 10 on the Mohs scale, making it ideal for jewelry that endures daily wear, such as engagement rings. Diamond is composed of pure carbon atoms arranged in a crystal structure, which gives it its unique optical properties, including high refractive index and dispersion, contributing to its fiery sparkle.
Historically, diamonds have been treasured for millennia, with early mining in India dating back to the 4th century BCE. They were later discovered in Brazil in the 18th century and in South Africa in the 19th century, which significantly increased their availability. Today, major diamond sources include Russia, Botswana, Canada, and Australia, though diamonds are found in various locations worldwide. The value of a diamond is determined by the "Four Cs": carat weight, cut, color, and clarity, which collectively assess its quality and rarity.
Symbolically, diamond represents love, purity, and strength. It is often associated with eternal commitment, making it the quintessential stone for engagement and wedding jewelry. In metaphysical beliefs, diamond is thought to enhance clarity of thought and amplify energy, serving as a powerful tool for manifestation and spiritual growth.

Caring for diamond jewelry is relatively simple due to its hardness. It can be cleaned with a solution of mild detergent and warm water, using a soft brush to remove dirt. Ultrasonic cleaners are generally safe for diamonds but should be used with caution for jewelry with other gemstones or settings. Diamond's timeless appeal and durability make it a cherished heirloom, passed down through generations.
May: Emerald
Emerald is the birthstone for May, celebrated for its vibrant green color and rich history. As a variety of beryl, emerald owes its color to trace amounts of chromium and sometimes vanadium. Its green hue ranges from light to deep forest green, often with natural inclusions known as "jardin," which are considered part of its character and do not detract from its value. Historically, emeralds have been mined for over 4,000 years, with ancient Egyptians valuing them highly; Cleopatra was famously fond of emeralds and had mines dedicated to them.
Gemologically, emerald has a hardness of 7.5 to 8 on the Mohs scale, but it is more brittle than other beryl varieties due to its inclusions and cleavage. This makes it less suitable for rings worn daily unless set in protective settings. Major sources of emerald include Colombia, which produces the finest quality stones, as well as Zambia, Brazil, and Zimbabwe. Colombian emeralds are particularly prized for their intense green color and transparency.
Symbolically, emerald represents rebirth, love, and wisdom. It is believed to promote growth, harmony, and patience, making it a stone of renewal and vitality. In metaphysical traditions, emerald is associated with the heart chakra, enhancing emotional balance and compassion. These meanings add depth to emerald jewelry, making it a popular choice for gifts and personal adornment.
Caring for emerald requires gentle handling. It should be cleaned with a soft, damp cloth and mild soap, avoiding harsh chemicals or ultrasonic cleaners that could damage the stone. Due to its inclusions, emerald is more prone to chipping, so it should be stored carefully and not subjected to rough treatment. For those born in May, emerald offers a lush and meaningful gemstone that embodies the beauty of nature.

Pearls range in color from white and cream to black and gold, depending on the type of mollusk and environmental conditions. Historically, pearls have been symbols of purity and innocence, used in royal jewelry for centuries.
Alexandrite is a rare color-changing gemstone, discovered in the Ural Mountains of Russia in the 1830s. It appears green in daylight and red under incandescent light, a phenomenon caused by its unique crystal structure and trace elements. This dramatic color shift makes Alexandrite highly valued and often cited as one of the most valuable birthstones due to its rarity. It has a hardness of 8.5 on the Mohs scale, making it durable for jewelry.
Moonstone is a variety of feldspar known for its adularescence, a shimmering optical effect that gives it a mystical glow.

The finest rubies, known for their "pigeon's blood" red, come from Myanmar (Burma), though other sources include Thailand, Sri Lanka, and Mozambique.
Ruby has a hardness of 9 on the Mohs scale, making it one of the hardest gemstones and highly suitable for jewelry.
