This article delves into the multifaceted significance of the September 15th birthstone, exploring the sapphire's geological formation, gemological properties, and historical journey, while also examining the roles of opal and carnelian in enriching the date's gemstone tradition.
The Sapphire: A Symbol of Nobility and Wisdom
Sapphires are among the most revered gemstones in the world, not only for their beauty but also for their symbolic and historical significance. The sapphire is the primary birthstone for September, and it is particularly associated with those born on the 15th of the month. Its deep blue color has long been linked to concepts such as wisdom, truth, and nobility. In ancient times, sapphires were believed to possess divine qualities and were often used in royal and religious contexts.
The history of sapphires dates back thousands of years, with evidence of their use in various ancient civilizations. The elite of ancient Greece and Rome believed that blue sapphires protected their owners from harm and envy. In the Middle Ages, clerics wore sapphires because they symbolized Heaven, and ancient Persians held a belief that the earth rested upon a giant sapphire, which in turn gave the sky its blue color. This gemstone has adorned royalty and the robes of the clergy for countless centuries, cementing its status as a gem of high esteem.
The September birthstone has traditionally symbolized sincerity, truth, faithfulness, and nobility. Its historical reputation extends to the realm of healing, with medieval Europeans believing that sapphire could cure plague boils and diseases of the eye, and that it served as an antidote to poison. The allure of the sapphire is further magnified by famous specimens, such as the Rockefeller Sapphire, a 62.02-carat rectangular step-cut stone unearthed in Myanmar (Burma).
Geological Formation and Sources
Sapphires belong to the corundum mineral family, which also includes rubies. While rubies are defined by their red hues, sapphires encompass a wide range of colors, though blue is the most iconic and widely recognized. The name “sapphire” is derived from the Latin word “sapphirus” and the Greek word “sappheiros,” both of which historically referred to the blue gemstone.
Corundum is formed under specific geological conditions, typically in metamorphic rocks such as gneiss and schist, or in certain igneous rocks like basalt. The blue color in sapphires is primarily caused by trace amounts of iron and titanium within the crystal lattice. Significant sources of sapphire include Myanmar (Burma), which is renowned for producing some of the world's most prized blue sapphires. Other notable mining locations, while not explicitly detailed in the provided materials for September 15th, are understood in the broader gemological field to include Sri Lanka, Kashmir, and Australia, among others. The geological journey of a sapphire from its formation deep within the Earth's crust to its discovery by miners is a testament to the natural forces that create such enduring beauty.
Gemological Properties of Sapphire
The physical and optical properties of sapphire are what make it not only beautiful but also exceptionally durable, contributing to its popularity in jewelry.
- Hardness and Durability: Sapphires are among the hardest gemstones, ranking 9 on the Mohs scale of mineral hardness. This exceptional durability makes them an excellent choice for various types of jewelry, from everyday wear to special occasion pieces. A hardness of 9 means that sapphire is resistant to scratching by all minerals except diamond and moissanite, ensuring that it can maintain its polish and brilliance for a lifetime.
- Chemical Composition: Sapphires are a variety of corundum, with a chemical formula of Al₂O₃ (aluminum oxide). The trace elements that substitute for aluminum in the crystal structure are responsible for the gem's color.
- Color and Clarity: While blue is the most famous color, sapphires occur in a "rainbow of other colors," as noted in the sources. These include pink, yellow, green, and even colorless varieties. The clarity of a sapphire can vary, with inclusions being common. However, certain inclusions can also be used to identify the gem's origin.
- Cut and Carat: Sapphires are cut into a variety of shapes to maximize their color and brilliance. The Rockefeller Sapphire, for example, was cut as a rectangular step cut. Sapphires are found in a range of sizes, with larger, high-quality stones being particularly valuable.

The Significance of Opal and Carnelian in September 15th Lore
While sapphires are the primary birthstone for September 15th, the inclusion of opal and carnelian adds to the date’s rich tapestry of gemstone lore. These stones, with their unique properties and symbolism, offer additional layers of meaning for those born on this date.
Opal: A Gemstone of Iridescent Beauty
Opal is a gemstone known for its iridescent play of colors, which is caused by the diffraction of light within its structure. Opal is composed of hydrated silica and is found in various parts of the world, including Australia, Mexico, and Ethiopia. The gemstone is particularly associated with September 15th and is listed as a secondary birthstone for the date.
Opal has long been associated with mystical and magical properties. In ancient Rome, opals were considered a symbol of hope and purity. In more recent times, opal has been linked to inspiration, creativity, and emotional healing. The gemstone is believed to enhance one’s ability to express emotions and is often used in jewelry designed to promote emotional balance.
From a geological perspective, opal is a relatively soft gemstone, with a rating of 5.5 to 6.5 on the Mohs scale of mineral hardness. This makes it more delicate than sapphires and requires careful handling to avoid damage. Opal should be cleaned with mild soap and warm water, using a soft cloth to avoid scratching the surface.

It is a durable gemstone, rating between 6.5 and 7 on the Mohs scale, making it suitable for use in everyday jewelry. Carnelian is associated with September 15th and is valued for its grounding energy and motivational qualities.
Historically, carnelian has been used as a protective talisman and a symbol of courage. It is believed to stimulate motivation, enhance creativity, and provide a sense of stability. The stone's warm color is often linked to vitality and passion. For those born on September 15th, carnelian offers a complementary energy to the sapphire, focusing on action, confidence, and emotional warmth.
Carnelian can be cleaned with mild soap and warm water, using a soft cloth to avoid scratching the surface. It is important to avoid exposing carnelian to harsh chemicals, as this can cause damage to the gemstone.
Care and Cleaning for September 15th Birthstones
The durability of each gemstone dictates the appropriate care and cleaning methods. Understanding these properties is essential for maintaining the beauty and longevity of birthstone jewelry.
- Sapphire (Hardness 9): Due to its exceptional hardness, sapphire is highly resistant to scratching and can be cleaned with relative ease. It can be washed in warm, soapy water and cleaned with a soft brush. Ultrasonic and steam cleaners are generally safe for sapphires, but it is always advisable to have the jewelry inspected by a professional, especially if it contains fractures or inclusions.
- Opal (Hardness 5.5-6.5): Opal is significantly softer and more porous than sapphire. It should be protected from sharp blows, extreme temperature changes, and harsh chemicals. Cleaning should be done gently with a soft, damp cloth. Avoid ultrasonic cleaners and steam, as the heat and vibrations can cause cracking.

It is more resistant to scratching than opal but should still be handled with care to avoid damage from harder materials. Avoid harsh chemicals and prolonged exposure to strong sunlight, which can fade its color over time.
