Sapphire, the designated birthstone for the month of September, stands as one of the most revered gemstones in history. Renowned for its deep, celestial blue hues, this gem belongs to the corundum mineral family, the same family as ruby. Its significance extends far beyond its captivating color, weaving through millennia of human history, royalty, religion, and modern jewelry. For individuals born on September 19th, the sapphire carries a particularly potent symbolism, believed to foster clarity of thought, emotional balance, and inner peace. This article delves into the sapphire’s rich history, its geological origins, its precise gemological properties, and the enduring metaphysical beliefs that have cemented its status as a treasured gemstone for centuries.
History and Lore
The sapphire’s history is as deep and layered as its most prized blue color. Its name itself is a testament to its ancient origins, deriving from the Latin sapphirus and the Greek sappheiros, both terms referring to the color blue. For countless centuries, sapphire has been a stone of royalty and clergy, adorning crowns, scepters, and religious vestments. Its association with the divine and the heavens is a recurring theme across various cultures and eras.
In ancient Greece and Rome, the elite believed that blue sapphires offered protection from harm and envy. The gemstone was not merely an ornament but a talisman for safety and virtue. This protective quality was further emphasized in medieval Europe. Clerics of the Middle Ages wore sapphires as a symbol of Heaven, believing the gem’s blue hue mirrored the divine realm. The Persians held a cosmological belief that the earth rested upon a giant sapphire, and that the reflection of this colossal stone was what gave the sky its blue color. This belief underscores the gemstone’s profound connection to the heavens and spiritual purity.
Beyond its protective and symbolic roles, the sapphire was also reputed to possess healing powers. Medieval Europeans believed the gem could cure plague boils and diseases of the eye. It was also thought to serve as an antidote to poison, a belief that made it a valuable stone for those in positions of power who might face such threats. The sapphire’s journey to becoming the official September birthstone is a more modern development. The American National Association of Jewelers, now known as Jewelers of America, led the initiative to standardize a list of birthstones, assigning sapphire to the month of September. This designation has since prevailed both within the United States and internationally, solidifying its status as the quintessential September gem.
Geological Formation and Sources
Sapphire, like all corundum, is a form of crystalline aluminum oxide (Al₂O₃). Its formation requires specific geological conditions, primarily the presence of aluminum and oxygen under high heat and pressure, often in metamorphic or igneous rock environments. Trace elements, notably iron and titanium, are responsible for the gem’s iconic blue color. The precise combination and concentration of these elements determine the specific shade of blue, from the velvety cornflower blue to the deep, inky navy.
While sapphires are found in various locations across the globe, certain regions are particularly renowned for producing high-quality specimens. A notable example is the famous Rockefeller Sapphire, a 62.02-carat rectangular step-cut stone that was unearthed in Myanmar (Burma). Myanmar, along with Sri Lanka (formerly Ceylon) and Kashmir, has historically been a primary source for the world’s finest blue sapphires. These regions are celebrated for producing sapphires with exceptional color saturation and clarity. Other significant sources include Australia, Thailand, Cambodia, and parts of Africa and the United States (Montana). The geographic origin of a sapphire can significantly influence its value and desirability, with certain locales commanding a premium in the gem market.
Gemological Properties
The sapphire is celebrated not only for its color but also for its remarkable physical characteristics, which contribute to its durability and suitability for a wide range of jewelry applications.
Hardness and Durability One of the most significant properties of sapphire is its exceptional hardness. Ranking 9 on the Mohs scale of mineral hardness, sapphire is second only to diamond (which ranks 10). This makes it one of the toughest gemstones in nature, highly resistant to scratching and abrasion. Its hardness, combined with its vibrant color and clarity, makes it an ideal choice for jewelry that is intended for everyday wear, such as engagement rings, pendants, and earrings. The durability of sapphire is a perfect representation of enduring qualities, which is why it is also celebrated as the traditional gift for the 5th and 45th wedding anniversaries, symbolizing loyalty, trust, and deep commitment.
Color and Clarity While blue is the most famous and sought-after color for sapphire, the gemstone occurs in a wide range of hues, with the exception of red (which is classified as ruby). These other colors, often referred to as "fancy sapphires," include pink, yellow, green, and purple. The color variation is due to different trace elements present during formation. For blue sapphires, the presence of both iron and titanium is key. In terms of clarity, sapphires can contain inclusions, but high-quality stones are prized for their transparency and lack of visible flaws. The presence of certain inclusions, like fine silk (rutile needles), can sometimes enhance the gem's value by creating a star effect in cabochon cuts.
Cut and Carat The cut of a sapphire is chosen to maximize its color and brilliance. Common cuts for sapphires include oval, round, cushion, and emerald cuts, as well as cabochons for star sapphires. The choice of cut depends on the shape of the rough stone and the desired final appearance. Sapphires are often set in gold or platinum jewelry, settings that complement their rich color and durability. Sapphires are found in a range of carat sizes, from small accent stones to large, museum-quality specimens like the Rockefeller Sapphire. Larger, high-quality sapphires are exceptionally rare and command premium prices.

Symbolism and Metaphysical Beliefs
The sapphire’s symbolism is deeply intertwined with its historical use and visual properties. It has long been associated with wisdom, loyalty, and nobility, making it a fitting birthstone for those born in September, particularly on the 19th.
Core Symbolism Traditionally, the sapphire birthstone has symbolized sincerity, truth, faithfulness, and nobility. These attributes are rooted in the gem’s historical associations with royalty and the clergy. Its deep blue color is often linked to the heavens and spiritual purity, reinforcing its connection to truth and divine favor. For individuals born on September 19th, sapphires are believed to possess specific meanings that promote clarity of thought, emotional balance, and inner peace.
Metaphysical and Healing Beliefs Beyond its symbolic meanings, sapphire is attributed with various metaphysical properties. In ancient times, it was believed to offer protection from harm and envy. Medieval Europeans attributed healing powers to the gem, using it to treat ailments of the eye and to ward off plague. It was also considered an antidote to poison. In modern metaphysical beliefs, sapphire is often referred to as a "stone of protection" and is said to encourage clear thinking, confidence, and inner strength. For men born in September, sapphire is believed to enhance these qualities, making it a meaningful talisman for both personal and professional life.
Cultural and Anniversary Significance The sapphire’s symbolism extends to its role in cultural traditions and gift-giving. As the anniversary gemstone for the 5th and 45th years of marriage, it represents the lasting qualities of a strong relationship. Its durability mirrors the resilience and deepening commitment over time. This dual role as both a birthstone and an anniversary stone underscores its universal appeal as a gem of enduring significance.
Care and Cleaning
Given its exceptional hardness (9 on the Mohs scale), sapphire is a relatively easy gemstone to care for and is suitable for daily wear. However, proper maintenance is essential to preserve its beauty and luster.
Cleaning Methods Sapphires can be safely cleaned using warm water, a mild detergent, and a soft brush. Ultrasonic cleaners and steam cleaners are generally safe for sapphires, but caution is advised if the stone has been treated or has fractures. It is always best to consult with a professional jeweler before using these methods, especially for heirloom or high-value pieces.
Storage and Handling To prevent scratching, sapphires should be stored separately from other gemstones and jewelry, ideally in a soft-lined compartment of a jewelry box. While sapphire is highly durable, it is not indestructible. Avoid exposing it to sharp blows or extreme temperature changes, which could potentially damage the stone or its setting. For jewelry set with sapphires, regular checks of the setting are recommended to ensure the stone remains secure.
