History and Lore
The sapphire has long been associated with wisdom, truth, and divine favor. Its name is derived from the Greek word sappheiros, which means "blue" or "precious stone." The deep blue color of the sapphire has been a source of fascination and reverence in many ancient cultures, often linked to the heavens and the divine. In ancient Greece and Rome, sapphires were considered protective stones, believed to ward off harm and envy. Roman scholars such as Pliny the Elder wrote about the sapphire’s mystical properties, noting its role in promoting clarity of thought and emotional stability.
During the Middle Ages, sapphires were closely tied to religious symbolism. Clerics wore sapphire rings as a sign of faith and sincerity, and the stone was thought to represent the heavens. The medieval belief that the earth rested on a giant sapphire, which gave the sky its blue color, further reinforced the stone's association with the divine.
In the context of September 28th, the sapphire holds a special significance as a birthstone that enhances the natural traits of individuals born on this date.

The sapphire also has a storied presence in royal history. Kings and queens have long adorned themselves with sapphire jewelry, seeing the stone as a symbol of power and divine right. One notable example is the sapphire engagement ring worn by Princess Diana, which later became the ring of choice for Kate Middleton when she married Prince William. This royal endorsement has only increased the sapphire’s prestige and appeal as a birthstone and a symbol of enduring love.
Geological Formation and Sources
Sapphires are a type of corundum, a mineral composed of aluminum oxide (Al₂O₃). While corundum is naturally colorless, trace amounts of various elements can impart different hues to the stone. In the case of the sapphire, the presence of iron and titanium creates the iconic blue coloration. The more iron present, the deeper the blue. Sapphires can also occur in a range of other colors—green, yellow, orange, pink, and even purple—depending on the specific trace elements involved. These non-blue sapphires are often referred to as "fancy sapphires."
Sapphires form deep within the Earth’s crust under conditions of high pressure and temperature. They are typically found in metamorphic and igneous rocks, often in association with minerals like zircon and rutile. The gemstone is mined in several regions around the world, with the most notable sources including:
- Myanmar (Burma): Renowned for producing some of the finest blue sapphires, particularly those with a rich cornflower blue color.
- Australia: A major source of high-quality sapphires, especially from the state of New South Wales.
- Afghanistan: Known for its deep blue sapphires, which have been mined for thousands of years.
- Sri Lanka: A traditional source of sapphires, with a long history of gemstone trade.
- Madagascar: A growing source of sapphires, producing stones in a wide range of colors.
- United States: Sapphires are also found in states like Montana and North Carolina, though these tend to be smaller in size and lower in color intensity.
In terms of availability, commercial-grade sapphires are found in East Africa, Australia, and Montana, USA. The increasing popularity of lab-created sapphires has also introduced an ethical and environmentally friendly alternative to natural sapphires, making the gemstone more accessible to a broader audience.

Gemological Properties
Sapphires are among the hardest gemstones, ranking 9 on the Mohs scale of mineral hardness. This places them just below diamonds (10) and moissanite (9.25), making them highly durable and suitable for everyday wear. Their toughness is further enhanced by their excellent resistance to scratches and abrasions, though they do have a cleavage plane, which can make them susceptible to chipping if struck at the right angle.
The refractive index of sapphires typically ranges from 1.76 to 1.78, which means they exhibit a moderate to high level of brilliance when cut and polished correctly. Sapphires are typically transparent to translucent, with clarity grades ranging from flawless to included. Inclusions are common in natural sapphires and can often add to the stone’s character, especially if they are not visible to the naked eye.
Color is one of the most important factors in determining a sapphire’s value and appeal. While blue sapphires are the most well-known and sought after, the term "sapphire" encompasses a wide range of colors. For example:
- Yellow sapphires are caused by the presence of iron and chromium.
- Pink sapphires owe their color to high chromium content.
- Purple sapphires are the result of a combination of iron, titanium, and chromium.
The most valuable sapphires are those with a deep, even blue color and high clarity. The intensity of the blue color is often described using terms like "cornflower blue," "royal blue," or "violet blue." The presence of trace elements and the way the stone is cut can significantly influence its final appearance and market value.
Symbolism and Metaphysical Beliefs
Sapphires have long been associated with a range of symbolic and metaphysical properties. In ancient times, they were believed to promote wisdom, clarity, and inner peace. The stone was thought to enhance the wearer’s ability to think clearly and make sound decisions, making it a popular choice for scholars, leaders, and spiritual seekers.
In medieval Europe, sapphires were believed to have protective properties. They were said to shield the wearer from envy, harm, and negative influences. Clergy and monks often wore sapphire rings as a symbol of their faith and as a means of invoking divine protection.
Sapphires are also associated with the concept of truth and sincerity. They are often given as gifts to symbolize honesty, loyalty, and enduring love. In many cultures, sapphires are believed to strengthen relationships and foster trust between partners. The stone’s association with the soul and the divine makes it a powerful symbol of spiritual growth and enlightenment.
In the context of September 28th, the sapphire serves as a meaningful talisman for those born on this date.

Care and Cleaning
Given its high hardness and durability, the sapphire is well-suited for everyday wear. However, like all gemstones, it requires proper care to maintain its beauty and longevity. Here are some general guidelines for cleaning and maintaining sapphire jewelry:
- Cleaning: Sapphires can be cleaned using a soft brush, mild soap, and warm water. A gentle ultrasonic cleaner can also be used, though it is important to avoid using harsh chemicals or abrasive materials, which can damage the stone or the setting.
- Storage: When not in use, sapphire jewelry should be stored in a soft, padded container to prevent scratches and impacts. It is best to keep sapphires separate from harder gemstones like diamonds, which can cause scratches.
- Avoiding Damage: While sapphires are durable, they do have a cleavage plane, which can make them vulnerable to chipping if struck at the right angle. It is important to avoid exposing sapphire jewelry to heavy impacts or sudden temperature changes.
- Professional Maintenance: Periodically, it is advisable to have sapphire jewelry inspected by a professional jeweler to check for any loose stones, wear on the setting, or signs of damage.
By following these simple care tips, sapphire jewelry can be enjoyed for a lifetime, preserving its beauty and value for generations to come.
