Beyond the Calendar: What Are Birthstones by Month?
For centuries, people have associated specific gemstones with the month of their birth, believing these stones hold unique powers and meanings. But what exactly are birthstones by month, and how has this tradition evolved? While many are familiar with the classic chart, the story behind these gems is far richer and more dynamic than you might imagine. At Wilton Jewelers, we believe understanding this heritage can help you choose a piece of jewelry that’s not only beautiful but also deeply personal.
The concept of birthstones isn’t as ancient as one might think. the modern list largely stems from a 1912 proposal by the Jewelers of America. However, historical texts, such as those from the Old Testament and ancient India, do mention precious stones linked to astrological signs or specific times of year. These early connections laid the groundwork for the birthstone traditions we recognize today.
The Evolving Birthstone Chart: A Journey Through Time
The list of birthstones by month isn’t static. It has been shaped by cultural shifts, trade routes, and even the discovery of new gemstones. The earliest known references, dating back thousands of years, often linked stones to the twelve zodiac signs rather than twelve specific months. For instance, ancient Sanskrit texts described a constellation of 80 precious gems, associating them with Hindu astrology. According to the Gemological Institute of America (GIA) (2023), the concept of monthly birthstones as we know it began to solidify in the 15th century, but it was standardized in the early 20th century.
The most influential shift occurred in 1912 when the Jewelers of America committee, with input from jewelers and gem experts, established a more definitive list. This 1912 chart included stones like Pearl, Emerald, Ruby, and Sapphire, but some months had multiple options or lacked a widely accepted gem. The most significant modern update occurred in 1952 when the Jewelry Industry Council of America (JICA) refined the list, notably adding Alexandrite for June and Tanzanite for December, and solidifying the modern birthstone chart.
January: Garnet’s Fiery Depths
January’s traditional birthstone is the Garnet. Often associated with the color red, garnets actually come in a surprising array of hues, including vibrant greens (like Tsavorite Garnet), oranges, and purples. Historically, garnets were believed to protect travelers and ward off nightmares. According to folklore, they provided light in darkness and offered protection against evil. The deep red variety, Pyrope Garnet, is especially renowned for its rich color and symbolic association with passion and commitment.
Practical Tip: Garnets rate between 6.5 and 7.5 on the Mohs hardness scale, making them suitable for everyday wear, though care should still be taken to avoid harsh impacts. Consider garnet earrings or a pendant for a touch of enduring warmth.
February: Amethyst’s Royal Hue
February’s birthstone is Amethyst, a variety of quartz celebrated for its stunning purple shades, ranging from pale lilac to deep violet. Ancient Greeks believed amethyst stones could prevent intoxication, a property derived from the myth of the god Bacchus. The name ‘amethyst’ itself comes from the Greek word ‘amethystos,’ meaning ‘not drunk.’ Amethyst is also associated with clarity of mind and spiritual awareness.
Practical Tip: Amethyst scores a 7 on the Mohs scale, offering good durability. It’s an excellent choice for rings, pendants, and bracelets. Its color can be enhanced by certain cuts, so look for stones with even saturation.
March: Aquamarine and Bloodstone’s Serenity and Courage
March boasts two birthstones: Aquamarine and Bloodstone. Aquamarine, with its serene blue-green hues reminiscent of the sea, is thought to bring calm, clarity, and courage to its wearer. Its name comes from the Latin ‘aqua marina,’ meaning ‘water of the sea.’ Bloodstone, a deep green jasper with red flecks, was historically used to stop bleeding and is associated with courage and selflessness. The red spots are thought to resemble drops of blood, linking it to healing and vitality.
Practical Tip: Aquamarine measures 7.5 to 8 on the Mohs scale, making it quite durable. Bloodstone is a 6.5 to 7. Look for clear, vibrant Aquamarines with minimal inclusions. For Bloodstone, the contrast between the green and red is key.
April: The Diamond’s Eternal Sparkle
April’s celebrated birthstone is the Diamond. Renowned for its brilliance, hardness, and rarity, diamonds have long symbolized eternal love, strength, and invincibility. The word ‘diamond’ comes from the Greek word ‘adamas,’ meaning ‘unconquerable.’ Diamonds are the hardest natural substance on Earth, scoring a perfect 10 on the Mohs scale, making them exceptionally resistant to scratching.
Practical Tip: Due to their hardness, diamonds are ideal for engagement rings and any piece intended for daily wear. When selecting a diamond, consider the 4 Cs: Carat, Cut, Color, and Clarity. A well-cut diamond will maximize its sparkle.
May: Emerald’s Lush Green
May’s birthstone is the Emerald, a precious gemstone celebrated for its vibrant, deep green color. Emeralds have been prized for millennia, associated with love, rebirth, and prosperity. Cleopatra was famously fond of emeralds. According to Smithsonian Magazine (2023), ancient Romans believed emeralds enhanced vision and promoted eloquence. Their characteristic green hue comes from trace amounts of chromium or vanadium.
Practical Tip: Emeralds are more delicate than diamonds, rating 7.5 to 8 on the Mohs scale, and often have inclusions that can affect their durability. Avoid exposing emeralds to harsh chemicals or sudden temperature changes. Emerald-cut is a popular choice, but consider protective settings like bezels for rings.
June: Pearl, Alexandrite, and Moonstone’s Versatility
June is unique in having three recognized birthstones: Pearl, Alexandrite, and Moonstone. Pearls, formed within mollusks, are organic gems and symbolize purity, innocence, and wisdom. Alexandrite, a rare color-changing gemstone, famously shifts from green in daylight to red under incandescent light. This phenomenon is a key indicator of its value. Moonstone, known for its adularescence (a milky, luminous sheen), is associated with intuition, dreams, and feminine energy.
Practical Tip: Pearls are relatively soft (2.5-3 on Mohs) and require gentle care. avoid perfumes and cosmetics directly on them. Alexandrite and Moonstone rate 6 to 6.5 on the Mohs scale. Look for strong color change in Alexandrite and a good ‘flash’ in Moonstone.
July: Ruby’s Passionate Glow
July’s birthstone is the Ruby, a precious gem revered for its intense red color and associated with passion, protection, and prosperity. The finest rubies are often described as having a ‘pigeon’s blood’ red hue. According to GIA (2023), rubies are a variety of the mineral corundum, the same as sapphires, and rate a 9 on the Mohs hardness scale, making them extremely durable.
Practical Tip: Rubies are excellent for all types of jewelry due to their hardness. When choosing a ruby, prioritize a vibrant, even color. Heat treatment is common for rubies to enhance color and clarity — which is generally accepted in the trade.
August: Peridot and Spinel’s Vibrant Charm
August welcomes Peridot and Spinel as its birthstones. Peridot, known for its distinctive yellowish-green hue, is a gem formed deep within the Earth’s mantle and brought to the surface by volcanic activity. It’s often associated with strength and protection. Spinel, a gemstone that comes in a wide spectrum of colors (including vibrant reds, pinks, and blues), was often mistaken for other precious stones like rubies and sapphires throughout history. According to Mindat.org (2023), many famous historical ‘rubies’ in royal collections are actually spinel.
Practical Tip: Peridot rates 6.5 to 7 on the Mohs scale and can be prone to chipping. Spinel is much harder, rating 8. Look for eye-clean stones in both varieties. Peridot’s vibrant green is best appreciated in cuts that maximize its color.
September: Sapphire’s Celestial Blue
September’s birthstone is the Sapphire, most famously known for its deep blue color, though sapphires also occur in nearly every other color (except red — which is a ruby). Sapphires symbolize wisdom, virtue, and good fortune. Historically, they were believed to protect against evil and illness. Like rubies, sapphires are corundum and rate a 9 on the Mohs scale, offering excellent durability.
Practical Tip: Blue sapphires are a fantastic choice for engagement rings or everyday jewelry. Consider the color saturation and tone when selecting a sapphire. While traditionally blue, fancy colored sapphires offer unique and beautiful alternatives.
October: Opal and Tourmaline’s Kaleidoscope
October is represented by two captivating gemstones: Opal and Tourmaline. Opals are famous for their ‘play-of-color,’ a unique phenomenon where flashes of spectral colors dance across their surface. they’re associated with creativity, hope, and purity. Tourmaline, a complex borosilicate mineral, comes in an astonishing range of colors and color combinations, from vibrant pinks and greens to deep blues and blacks. This diversity makes tourmaline incredibly versatile.
Practical Tip: Opals are relatively soft (5.5-6.5 on Mohs) and porous, requiring careful handling and avoiding water or chemicals. Tourmaline ranges from 7 to 7.5 on the Mohs scale. Look for opals with strong, distinct color flashes. For tourmaline, vibrant, evenly distributed color is desirable.
November: Topaz and Citrine’s Warmth
November’s birthstones are Topaz and Citrine. Topaz occurs in a variety of colors, including yellow, pink, blue, and brown, though golden yellow is often considered its classic hue. It’s associated with strength and intelligence. Citrine, a yellow to brownish-orange variety of quartz, is known for its cheerful energy and is believed to bring abundance and prosperity. It shares the 7 Mohs hardness rating with amethyst.
Practical Tip: Topaz rates 8 on the Mohs scale, making it very durable. Citrine, being quartz, rates a 7. Many blue topaz stones are colorless topaz that has undergone irradiation and heating. Consider the specific color and clarity when selecting these gems.
December: Turquoise, Zircon, and Tanzanite’s Cool Tones
December is celebrated with three distinct birthstones: Turquoise, Zircon, and Tanzanite. Turquoise, an opaque gemstone, is prized for its unique blue-to-green shades and is often associated with protection, healing, and good fortune. Zircon, a natural gemstone (distinct from synthetic cubic zirconia), comes in various colors and is known for its brilliance and durability (7-7.5 Mohs). Tanzanite, a relatively new gem discovered in Tanzania in the late 1960s, is famed for its striking violet-blue color and pleochroism (displaying different colors from different angles). According to The New York Times (2007), Tanzanite’s discovery transformd the gemstone market for December birthdays.
Practical Tip: Turquoise is porous and relatively soft (5-6 Mohs), requiring careful wear. Zircon is durable but can be brittle. Tanzanite rates 6.5 to 7 on the Mohs scale and is best protected from hard knocks. Its beauty is often enhanced by heat treatment.
Choosing Your Perfect Birthstone: Beyond the List
While the traditional birthstone lists offer wonderful guidance, at Wilton Jewelers, we encourage you to choose a gemstone that resonates with you personally. Perhaps a certain color catches your eye, or a gemstone’s meaning speaks to your aspirations. Don’t feel limited by your birth month! Many people opt for stones associated with their favorite color, a significant life event, or even a loved one’s birthstone.
Consider the durability of a gemstone if you plan to wear it daily. For example, a diamond or sapphire is an excellent choice for an engagement ring due to its hardness (10 and 9 on the Mohs scale, respectively). For more delicate pieces or occasional wear, softer stones like pearls or opals can be beautiful choices. Mohs hardness scale (ranging from 1 for talc to 10 for diamond) is Key for selecting jewelry that will last.
Wilton Jewelers’ Advice: If you’re drawn to a stone not traditionally associated with your birth month, wear it with pride! Jewelry is a form of self-expression. We often see clients choosing stones like morganite or moissanite for their beauty and symbolism, regardless of month. We also recommend consulting with a jeweler to understand treatments and care for specific gemstones.
