The concept of birthstones has evolved over millennia, with origins traceable to the biblical Book of Exodus, which describes a High Priest’s breastplate adorned with twelve gemstones, each representing a tribe of Israel.

From the fiery red of January’s garnet to the vibrant blues of December’s tanzanite, each gemstone tells a story of Earth’s artistry and human belief.
January: Garnet
The birthstone for January is garnet, a gemstone celebrated for its remarkable diversity and enduring appeal. Historically, garnet has been associated with constancy and loyalty, making it a popular choice for meaningful jewelry. Its name is derived from the Latin word granatum, meaning pomegranate, due to the resemblance of its deep red crystals to the fruit’s seeds. However, garnet is not limited to red; it encompasses a family of silicate minerals with a wide color range, including vibrant oranges, greens, purples, and even rare blue varieties.
Garnet is mined in various locations worldwide, with significant deposits found in India, Sri Lanka, and parts of Africa. The stone’s chemical composition varies by species, but all garnets share a similar crystal structure and hardness. On the Mohs scale, garnet typically registers around 7, making it reasonably tough and suitable for everyday jewelry. This durability, combined with its affordability and color variety, has cemented its status as a beloved birthstone. While most garnet species are not considered rare, the discovery of blue garnets in the 1990s added an element of exclusivity to the family, captivating collectors and gemologists alike.
Beyond its physical properties, garnet carries a rich tapestry of lore. Ancient civilizations believed it could ward off evil and provide protection during travel. In modern metaphysics, it is often linked to vitality and regeneration, thought to energize the wearer and inspire passion. For January-born individuals, garnet serves as a symbol of strength and resilience, its deep hues echoing the winter month’s quiet intensity.
February: Amethyst
Amethyst, the purple variety of quartz, is February’s traditional and modern birthstone. This gemstone has long been prized for its soothing color and perceived healing properties. Historically, amethyst was considered a stone of royalty, once as valuable as ruby and emerald. Its name comes from the Greek word amethystos, meaning "not intoxicated," reflecting the ancient belief that it could prevent drunkenness and sharpen the mind. This lore made it a favorite among European nobility and clergy.
Amethyst is primarily mined in Brazil, Zambia, and Uruguay, though significant deposits also exist in Russia and the United States. As a quartz variety, its chemical formula is silicon dioxide (SiO₂), and it typically exhibits a hardness of 7 on the Mohs scale. The stone’s color ranges from pale lavender to deep violet, with the most prized hues displaying even saturation and minimal zoning. While amethyst was once a rare and expensive gem, large-scale discoveries in the 19th century made it more accessible, allowing it to become a staple in contemporary jewelry.
In addition to its historical association with sobriety, amethyst is believed to promote calmness and spiritual awareness. It is often used in meditation practices and is thought to enhance intuition and emotional balance. For those born in February, amethyst represents sincerity and peace, its calming purple tones offering a sense of tranquility during the winter months.
March: Aquamarine and Bloodstone
March is unique in having two birthstones: aquamarine and bloodstone. Aquamarine, the modern choice, derives its name from the Latin for "seawater," aptly describing its tranquil blue to blue-green hues. Historically, sailors carried aquamarine as a talisman for protection and safe passage, believing it could calm stormy seas. This gemstone is a variety of beryl, sharing a family with emerald and morganite, and is prized for its exceptional clarity and transparency.
Aquamarine is primarily sourced from Brazil, Nigeria, and Madagascar. Its chemical composition is beryllium aluminum silicate, and it boasts a hardness of 7.5 to 8 on the Mohs scale, making it durable enough for rings and pendants. The most valuable aquamarines display a deep, saturated blue with minimal inclusions, though lighter shades are more common. The stone’s lore extends to its metaphysical properties, where it is associated with courage, clarity, and communication. It is often called the "stone of courage" and is believed to soothe fear and reduce stress.
The traditional birthstone for March is bloodstone, also known as heliotrope. This opaque green chalcedony is speckled with red iron oxide inclusions, which resemble drops of blood. Bloodstone has a rich history, with ancient Egyptians believing it could heal wounds and purify the body. It is a variety of quartz, with a hardness of 6.5 to 7, and is commonly found in India, Brazil, and Australia. Bloodstone is linked to vitality and strength, often used as an amulet for protection and endurance. For March-born individuals, the choice between the serene aquamarine and the robust bloodstone allows for personal expression, whether through calm clarity or resilient energy.
April: Diamond
Diamond, the birthstone for April, is renowned as the ultimate symbol of love, endurance, and luxury. Its name comes from the Greek word adamas, meaning "invincible," reflecting its unmatched hardness and durability. Historically, diamonds have been coveted by royalty and elites for centuries, with significant deposits discovered in India, Brazil, and later, South Africa. The stone’s allure lies in its brilliant optical properties, including high refractive index and strong dispersion, which give it unparalleled sparkle.
Diamonds are composed of pure carbon and are formed under extreme heat and pressure deep within the Earth’s mantle. They are mined in various countries, including Russia, Botswana, Canada, and Australia. On the Mohs scale, diamond is the hardest known natural material, scoring a perfect 10. This exceptional hardness makes it ideal for daily wear, though its brittleness requires careful handling to avoid chipping. The value of a diamond is determined by the 4Cs: carat weight, cut, color, and clarity. While colorless diamonds are most traditional, fancy colored diamonds (such as yellow, pink, or blue) have gained popularity for their uniqueness.
Beyond its physical attributes, diamond carries profound symbolism. It is associated with purity, eternal love, and invincibility, making it the quintessential gemstone for engagement rings. In metaphysical traditions, diamond is believed to amplify energy, enhance clarity, and promote spiritual enlightenment. For April-born individuals, diamond represents innocence and strength, a timeless gem that transcends trends and generations.
May: Emerald
Emerald, the birthstone for May, captivates with its vibrant green hue and rich historical legacy. This gemstone is a variety of beryl, colored by trace amounts of chromium and vanadium. Its name is derived from the Greek word smaragdus, meaning "green gem," and it has been treasured since antiquity. Ancient Egyptians mined emeralds as early as 1500 BCE, and Cleopatra famously adorned herself with these stones. The Muzo mines in Colombia remain the most renowned source, producing emeralds with the most prized deep green color.
Emeralds are also mined in Zambia, Brazil, and Afghanistan. As a beryl, its chemical formula is beryllium aluminum silicate, and it has a hardness of 7.5 to 8 on the Mohs scale. However, emeralds often contain inclusions, known as jardin, which are accepted as part of their character and can affect durability. The stone’s value is influenced by color, clarity, and origin, with Colombian emeralds commanding premium prices. Emeralds are treated with oil or resin to enhance clarity, a common practice in the trade.
Symbolically, emerald is associated with rebirth, fertility, and wisdom. It is believed to promote emotional balance and insight, making it a stone of intuition and growth. For those born in May, emerald embodies happiness and vitality, its lush green reflecting the renewal of spring.
June: Pearl and Alexandrite
June offers two distinct birthstones: pearl and alexandrite. Pearls are unique among gemstones as organic gems, formed within mollusks. Historically, pearls have been symbols of purity and wealth, with ancient civilizations like the Romans and Chinese valuing them highly. Natural pearls are rare and expensive, while cultured pearls, developed in the 20th century, made this gemstone more accessible. Pearls are primarily sourced from Japan, China, and the South Pacific, and they come in various colors, including white, cream, pink, and black.
Pearls have a hardness of only 2.5 to 4.5 on the Mohs scale, making them soft and susceptible to scratches. They require gentle care, avoiding chemicals and extreme temperatures. Metaphysically, pearls are linked to sincerity, wisdom, and emotional healing. They are often given as gifts to mark milestones, symbolizing purity and integrity.
Alexandrite, the modern birthstone for June, is a rare variety of chrysoberyl known for its dramatic color change—from green in daylight to red under incandescent light. Discovered in Russia’s Ural Mountains in the 1830s and named after Tsar Alexander II, it symbolizes balance and adaptability. Alexandrite is mined in Brazil, Sri Lanka, and East Africa, and its hardness of 8.5 on the Mohs scale makes it durable for jewelry. The stone’s color change is due to trace elements like chromium, and its value increases with the intensity of the shift. In lore, alexandrite is considered a stone of good fortune, bringing joy and optimism to the wearer. For June-born individuals, the choice between the organic elegance of pearl and the transformative beauty of alexandrite offers versatility in expression.
July: Ruby
Ruby, the birthstone for July, is a gem of passion and power. As a variety of corundum, its red color comes from chromium impurities. The name "ruby" is derived from the Latin ruber, meaning red, and it has been celebrated since ancient times. Historically, rubies were associated with vitality and protection, with Burmese warriors believing they could make them invincible in battle. The finest rubies, known as "pigeon’s blood," originate from Myanmar (Burma), though significant deposits are also found in Thailand, Sri Lanka, and Mozambique.
Ruby is composed of aluminum oxide (Al₂O₃) and has a hardness of 9 on the Mohs scale, second only to diamond. This exceptional durability makes it ideal for jewelry, though its value is heavily influenced by color saturation, with vivid reds commanding the highest prices. Rubies are often treated with heat to enhance color and clarity, a standard industry practice. In metaphysical traditions, ruby is believed to stimulate the heart, increase energy, and protect against negative forces. For July-born individuals, ruby symbolizes freedom and passion, its fiery hue embodying the intensity of summer.
August: Peridot and Spinel
August boasts two birthstones: peridot and spinel. Peridot, the traditional choice, is a gem variety of olivine, known for its vibrant olive-green color. Its name may derive from the Arabic faridat, meaning gem. Peridot has been mined since ancient Egypt, where it was called the "gem of the sun" and believed to protect against evil spirits. Today, major sources include the United States (Arizona), Pakistan, and China. Peridot’s chemical formula is (Mg,Fe)₂SiO₄, and it has a hardness of 6.5 to 7 on the Mohs scale. Its color is consistent and rarely treated, making it a popular choice for affordable jewelry. Symbolically, peridot is associated with friendship, prosperity, and protection, thought to bring good fortune and ward off nightmares.
Spinel, the modern addition for August, was often mistaken for ruby throughout history due to its similar color range. It is a magnesium aluminum oxide (MgAl₂O₄) with a hardness of 8 on the Mohs scale, making it durable and suitable for jewelry. Spinel is mined in Myanmar, Sri Lanka, and Tanzania, and it comes in a variety of colors, including red, blue, pink, and black. The red varieties, once confused with rubies, are particularly valued. In lore, spinel is believed to revitalize energy, reduce stress, and promote spiritual balance. For August-born individuals, the choice between the sunny peridot and the versatile spinel offers a spectrum of green and red hues to celebrate their summer birth month.
September: Sapphire
Sapphire, the birthstone for September, is a gem of wisdom, loyalty, and nobility. As a variety of corundum, it is known for its rich blue color, though it can occur in almost any hue except red (which is classified as ruby). Historically, sapphire has been associated with divine favor and protection; medieval clergy wore it to symbolize heaven, and ancient Persians believed the Earth rested on a giant sapphire. The finest blue sapphires come from Kashmir, Sri Lanka, and Myanmar, though deposits are also found in Australia, Thailand, and the United States.
Sapphire’s chemical composition is aluminum oxide (Al₂O₃), with trace elements like iron and titanium contributing to its blue color. It shares ruby’s hardness of 9 on the Mohs scale, ensuring excellent durability. Sapphires are often heat-treated to improve color and clarity, a widely accepted practice. Beyond blue, sapphires in colors like pink, yellow, and green are gaining popularity, known as "fancy sapphires." Metaphysically, sapphire is linked to mental clarity, truth, and spiritual insight. It is believed to enhance intuition and protect against negative thoughts. For September-born individuals, sapphire represents truth and wisdom, its deep blue evoking the clarity of autumn skies.
October: Opal and Tourmaline
October is represented by two birthstones: opal and tourmaline. Opal is an amorphous silica gemstone known for its play-of-color, a phenomenon where spectral colors flash across its surface as light refracts through microscopic silica spheres. Its name may come from the Sanskrit upala, meaning precious stone. Opal has been cherished since antiquity, with Roman historian Pliny the Elder noting its fiery beauty. Major sources include Australia (which produces most of the world’s opal), Ethiopia, and Mexico. Opal’s hardness ranges from 5.5 to 6.5 on the Mohs scale, making it relatively soft and requiring careful handling. It is often set in protective settings to avoid damage. In lore, opal is considered a stone of inspiration and creativity, believed to enhance imagination and emotional expression. However, due to its fragility, it is not recommended for daily wear in rings.
Tourmaline, the modern birthstone for October, is a complex borosilicate mineral known for its vast color range—from black to pink, green, and blue. Its name comes from the Sinhalese turmali, meaning "mixed gems." Tourmaline is mined in Brazil, Afghanistan, and Africa, and it has a hardness of 7 to 7.5 on the Mohs scale, making it more durable than opal. The stone’s variety includes watermelon tourmaline (green and pink), indicolite (blue), and rubellite (red). Historically, tourmaline was believed to have healing properties and could inspire creativity. Metaphysically, it is associated with balancing energy and promoting self-confidence. For October-born individuals, the choice between opal’s ethereal play-of-color and tourmaline’s vibrant spectrum offers a celebration of diversity and creativity.
November: Topaz and Citrine
November’s birthstones are topaz and citrine, both known for their warm, golden hues. Topaz, the traditional stone, is a silicate mineral that can be found in a range of colors, but it is most famously associated with imperial topaz, a rich orange-pink variety.

Topaz’s chemical formula is Al₂SiO₄(F,OH)₂, and it has a hardness of 8 on the Mohs scale, making it durable for jewelry. However, it is important to note that blue topaz is often color-treated, a common industry practice. In metaphysical traditions, topaz is linked to loyalty, love, and success, thought to bring joy and reduce stress.
Citrine, the modern alternative for November, is a yellow to orange variety of quartz. Its name comes from the French citron, meaning lemon. Citrine is often called the "merchant’s stone" for its association with prosperity and abundance. It is mined in Brazil, Madagascar, and the United States, and as a quartz variety, it has a hardness of 7 on the Mohs scale. Citrine is typically heat-treated amethyst or smoky quartz, a process that permanently changes its color. The stone is believed to energize the wearer, enhance creativity, and attract wealth. For November-born individuals, both topaz and citrine offer a warm, sunny palette, symbolizing loyalty and success.
December: Tanzanite, Turquoise, and Zircon
December is unique in having three birthstones: tanzanite, turquoise, and zircon. Turquoise, the traditional stone, is an opaque blue-green mineral composed of copper aluminum phosphate. Its name comes from the French pierre turquoise, meaning "Turkish stone," as it was brought to Europe from Turkey. Turquoise has been mined for over 5,000 years, with significant deposits in Iran, the southwestern United States, and China. It has a hardness of 5 to 6 on the Mohs scale, making it relatively soft and prone to scratching. Turquoise is often stabilized with resin to enhance durability. Metaphysically, it is considered a protective stone, associated with healing, wisdom, and good fortune. For centuries, it has been used as an amulet against harm.
Tanzanite, a modern addition for December, was discovered in Tanzania in the 1960s and named after the country. It is a variety of zoisite, known for its vivid blue-to-violet color. Tanzanite is mined exclusively in the Merelani Hills of Tanzania and is valued for its rarity and unique hue.
