This article delves into the history, properties, and cultural significance of sapphires, providing a detailed guide for anyone interested in the September birthstone.
History and Lore
Sapphires have a long and storied history, deeply embedded in the cultural and spiritual traditions of many civilizations. The term "sapphire" comes from the Greek word sappheiros, which is also the root of the name for the precious metal sapphire. This etymology reflects the gem’s association with the heavens and its sky-blue color.
In ancient Greece and Rome, sapphires were believed to offer protection from harm and envy. The elite of these civilizations wore sapphire jewelry as a symbol of status and safety. During the Middle Ages, sapphires were worn by clergymen to symbolize Heaven. Some ancient Persians believed the Earth rested on a giant sapphire, which explained the blue color of the sky. This belief highlights the sapphire’s association with the celestial and the divine.
Sapphires were also believed to have healing properties. Medieval Europeans thought that sapphires could cure plague boils and diseases of the eye. Additionally, they were considered an antidote to poison. These beliefs underscore the sapphire’s role not just as an adornment but also as a protective and healing stone.
In the modern era, sapphires have continued to be associated with royalty and romance. The famous sapphire engagement ring worn by Princess Diana and later by the Duchess of Cambridge, Kate Middleton, is a testament to the enduring appeal of sapphires in royal circles. This 12-carat blue sapphire, surrounded by diamonds, has become an iconic piece of jewelry and a symbol of enduring love and nobility.
Sapphires also have a place in the anniversaries of marriage. They are the traditional gemstone for the 5th and 45th wedding anniversaries. This dual significance highlights the sapphire’s role as a symbol of both youthful love and enduring partnership.
Geological Formation and Sources
Sapphires are a variety of the mineral corundum, which is composed of aluminum and oxygen. The chemical formula for sapphire is Al₂O₃, and its coloration is due to trace elements such as iron, titanium, and chromium. While sapphires are most commonly associated with their deep blue color, they can occur in a wide range of hues, including yellow, green, pink, purple, and even colorless. The blue color of sapphires is primarily due to the presence of iron and titanium.
The formation of sapphires occurs under high-pressure and high-temperature conditions deep within the Earth's crust. They are typically found in metamorphic and igneous rocks. The presence of impurities determines the final color of the gemstone. For example, a sapphire with a yellow or orange hue is caused by the presence of iron, while a pink sapphire is due to chromium.
Historically, some of the most important sources of sapphires have been Kashmir, Myanmar (formerly Burma), and Sri Lanka. These regions have produced some of the finest sapphires in the world. Kashmir sapphires, in particular, are known for their velvety blue color and are highly prized in the gemstone market.
In addition to these traditional sources, significant quantities of sapphires have also been found in countries such as Australia, Thailand, Cambodia, Madagascar, and the United States (Montana). These regions have become important in the global supply of sapphires and contribute to the availability of this gemstone in various markets.
One notable sapphire is the Rockefeller Sapphire, a 62.02-carat rectangular step-cut stone from Myanmar. Acquired in 1934 by financier and philanthropist John D. Rockefeller, Jr., this gem has undergone several recuts and remountings over the years. Initially set as a brooch, it was later remounted as a ring with two cut-cornered triangular diamond side stones. The Rockefeller Sapphire is a prime example of the enduring value and beauty of sapphires.
Gemological Properties
Sapphires are among the hardest and most durable gemstones, second only to diamonds on the Mohs scale of mineral hardness. With a hardness of 9, sapphires are highly resistant to scratches and wear, making them ideal for use in jewelry that is worn daily. This durability is one of the reasons why sapphires have been used in engagement rings and other heirloom pieces for centuries.
The refractive index of sapphires ranges from 1.76 to 1.78, and they have a specific gravity of 3.95 to 4.10. These properties are important for gemologists in identifying and evaluating sapphires. Sapphires are also known for their pleochroism, which means they can display different colors when viewed from different angles. This property is particularly noticeable in sapphires that are not of the traditional blue variety.
Sapphires can occur in a wide range of colors, but blue is the most commonly recognized and sought-after. The most prized blue sapphires are those with a velvety or cornflower blue hue. These stones are highly valuable and are often referred to as "Kashmir sapphires" due to their association with the Kashmir region.
The color of a sapphire can be enhanced through heat treatment, which is a common practice in the gemstone industry. Heat treatment can improve the color and clarity of a sapphire, making it more desirable for jewelry. However, it is important for consumers to be aware of whether a sapphire has been treated, as this can affect its value and durability.
Sapphires are also known for their luster, which is described as vitreous or glassy. This luster, combined with their hardness and refractive properties, makes sapphires highly attractive and suitable for a wide range of jewelry designs.
Symbolism and Metaphysical Beliefs
Sapphires have been imbued with various symbolic meanings and metaphysical beliefs throughout history. In ancient times, sapphires were believed to offer protection from harm and envy. They were also associated with divine favor and were worn by the clergy to symbolize Heaven. These beliefs highlight the sapphire’s connection to the spiritual and the sacred.
In medieval Europe, sapphires were believed to have healing properties. They were thought to cure diseases of the eye and act as an antidote to poison. These beliefs, while not supported by modern science, reflect the deep cultural significance of sapphires in historical contexts.
Sapphires have also been associated with nobility and truth. They have been worn by royalty and the elite as a symbol of status and power. The sapphire’s deep blue color has been linked to concepts of wisdom, clarity, and spiritual insight. In some traditions, sapphires are believed to enhance mental clarity and promote a sense of calm and peace.
The September birthstone is also associated with the zodiac signs of Virgo and Libra. In astrology, sapphires are believed to bring balance and harmony to those born under these signs. For Virgo, sapphires are said to enhance creativity and abundance, while for Libra, they are believed to promote fairness and justice.
Sapphires have also been linked to communication with the divine. In ancient times, people would wear sapphire rings when visiting oracles to increase the chances of receiving a prophecy. This belief underscores the sapphire’s role as a bridge between the earthly and the divine.
In addition to sapphires, other gemstones have been associated with September birthdays. Aventurine, for example, is linked to the zodiac sign Virgo and is believed to bring abundance, empathy, and creativity. However, sapphires remain the most prominent and historically significant birthstone for September.
Care and Cleaning
Due to their hardness and durability, sapphires are relatively easy to care for compared to other gemstones. However, proper cleaning and maintenance are essential to preserve their beauty and longevity.
Warm, soapy water is always a safe choice for cleaning sapphires. A gentle solution of mild dish soap and warm water can be used to clean sapphire jewelry. The gemstone can be soaked in this solution for a few minutes before being gently scrubbed with a soft-bristled brush. After scrubbing, the sapphire should be rinsed thoroughly with clean water and dried with a soft cloth.
Ultrasonic and steam cleaners are usually safe for untreated, heat-treated, and lattice diffusion-treated sapphires. These methods can be effective for removing dirt and debris from the gemstone and its setting. However, it is important to note that fracture-filled or dyed sapphires should only be cleaned with a damp cloth. These treatments can be damaged by ultrasonic or steam cleaning, which may cause the gemstone to lose its color or become discolored.
When wearing sapphire jewelry, it is advisable to avoid exposing it to harsh chemicals, such as household cleaners or chlorine. These substances can dull the gemstone’s luster and damage its setting. It is also a good idea to store sapphire jewelry separately from other gemstones to prevent scratches.
For those considering purchasing a sapphire, it is important to consult a reputable jeweler or gemologist. A professional can provide guidance on selecting a high-quality sapphire that meets the buyer’s preferences and budget. Factors to consider when purchasing a sapphire include color, clarity, cut, and carat weight. The most valuable sapphires are those with a deep, even blue color and minimal inclusions.
