Throughout history, gemstones have captivated humanity with their beauty, rarity, and perceived mystical properties. Among these, sapphire holds a particularly esteemed position, not only as the birthstone for September but also as a symbol of royalty, loyalty, and wisdom. This article delves into the history, geological origins, gemological characteristics, and cultural significance of sapphire, drawing upon available information to provide a comprehensive overview of this remarkable gemstone.
History and Lore
The association of gemstones with specific months and zodiac signs dates back to ancient times. The origins of birthstones can be traced to the twelve stones associated with the twelve signs of the zodiac, a tradition that evolved over centuries. The modern list of birthstones, as recognized today, was formalized in 1912 by the National Association of Jewellers in America.
Sapphires have long been favored by royalty and the upper classes. They symbolize loyalty and are also believed to focus the mind and encourage self-discipline. This association with nobility and virtue has cemented sapphire’s place in history and continues to influence its appeal today.
Geological Formation and Sources
Sapphire is a variety of the mineral corundum, an aluminum oxide (Al₂O₃) crystal. Corundum is renowned as the second hardest mineral after diamond, making sapphire exceptionally durable. While most commonly known for its blue hue, sapphires actually occur in every color except red – red corundum is known as ruby.
The sources for sapphires are geographically diverse. According to available information, sapphires featured in Beaverbrooks jewellery originate from Thailand, Brazil, Sri Lanka, Madagascar, and Australia. Many sapphires undergo a heat treatment process to enhance their color and clarity, a common practice within the gemological industry.
Gemological Properties
Sapphires possess a unique combination of physical and optical properties that contribute to their beauty and value. As a variety of corundum, sapphire registers a hardness of 9 on the Mohs scale, making it highly resistant to scratching and abrasion. This durability ensures that sapphire jewellery can withstand daily wear and maintain its brilliance for generations.
The signature characteristic of sapphire is its color, most famously a deep, saturated blue. However, as previously mentioned, sapphires can exhibit a wide range of colors, including pink, yellow, green, and even colorless. The color is determined by trace elements within the corundum crystal structure. For example, iron and titanium contribute to blue hues, while chromium can create pink or red tones.
The play of color, particularly notable in opals (another birthstone discussed in the provided sources), is not a defining characteristic of sapphire. Sapphire’s brilliance stems from its high refractive index and dispersion, which cause light to bend and separate into its spectral colors, creating a vibrant sparkle.
Here's a table summarizing key gemological properties:

Symbolism and Metaphysical Beliefs
Beyond its aesthetic appeal, sapphire carries significant symbolic weight. It is often associated with wisdom, truth, and faithfulness. The belief that sapphires focus the mind and encourage self-discipline highlights their perceived ability to promote mental clarity and inner strength.
Diamonds, another birthstone discussed in the provided sources, are also imbued with symbolism. They represent love, faithfulness, purity, and innocence, making them particularly popular choices for engagement and wedding rings. Diamonds are believed to open the mind to new possibilities and inspire imagination, while also providing strength and courage.
Care and Cleaning
Due to its exceptional hardness, sapphire is a relatively durable gemstone. However, like all jewellery, it requires proper care to maintain its brilliance. Sapphires can be safely cleaned using warm, soapy water and a soft brush. Avoid harsh chemicals or abrasive cleaners, as these can damage the gemstone’s surface. Regular cleaning will help remove dirt and oils, allowing the sapphire to sparkle at its best.

Several retailers offer a wide selection of birthstone jewellery, including rings, pendants, bracelets, and earrings. Beaverbrooks, Pandora, and H Samuel are specifically mentioned as sources for birthstone jewellery.
