Introduction
Sapphire, the birthstone of September, is celebrated for its stunning deep blue color. However, sapphires come in a variety of colors, and the term "sapphire" is not limited to blue stones. The sapphire is a variety of the mineral corundum, which also includes ruby when it appears red. The sapphire's color, derived from trace elements like titanium and iron, gives it a unique character that has fascinated humans for centuries. From ancient civilizations to modern royalty, the sapphire has played a significant role in history, culture, and gemology.
This article delves into the sapphire's color variations, its geological formation and sources, its historical significance, and the symbolism associated with it. We will also explore how to care for sapphires and their place in jewelry and fashion.
History and Lore
The sapphire has a long and storied history, with mentions dating back to ancient civilizations. The name "sapphire" comes from the Greek word "sappheiros," which is believed to have originally referred to lapis lazuli. Over time, the term came to denote the blue corundum we now recognize as sapphire. The sapphire's association with the color blue has made it a symbol of the sky and the heavens, and it has been linked to divine favor and wisdom.
In ancient Greece and Rome, sapphires were believed to offer protection and guidance. Greeks wore sapphires when seeking answers from oracles, and they were thought to bring clarity and insight. The sapphire's celestial blue color was associated with the sky and the divine, and it was believed to attract the favor of the gods. In the Middle Ages, sapphires were worn by clergymen and monarchs, symbolizing heaven and the soul. The stone was also believed to protect against harm and envy.
Buddhists and Hindus have also revered the sapphire for its spiritual significance. In Buddhist traditions, sapphires are believed to bring spiritual enlightenment and are used in meditation and worship. Hindu traditions also incorporate sapphires in religious ceremonies, where they are thought to enhance spiritual awareness and divine connection. The sapphire's deep blue color was seen as a reflection of the infinite and the divine.
One of the most famous historical associations with the sapphire is its role in the Ten Commandments. Ancient Hebrews believed that the commandments were inscribed on sapphire tablets, although modern historians now suggest that the reference may have been to lapis lazuli. Regardless, the sapphire's connection to sacred texts and divine law has reinforced its symbolic importance.
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 that sapphires held in the past.
The sapphire's association with royalty is another key aspect of its history. Sapphires have long been worn by kings, queens, and other members of the aristocracy. The deep blue color of the sapphire was linked to royalty and nobility, and it was often used in crowns, jewelry, and ceremonial robes. This connection has contributed to the term "royal blue," which refers to the rich, deep blue color of high-quality sapphires.
Modern history has also seen sapphires play a prominent role in significant events. One of the most famous sapphires is the 18-carat oval blue sapphire that was part of the engagement ring given by Prince Charles to Lady Diana Spencer in 1981. The ring has since passed to Catherine, Duchess of Cambridge, who wears it as her engagement ring. This sapphire has become a symbol of love and commitment, and it has helped to elevate the sapphire's status as a popular choice for engagement rings.
Geological Formation and Sources
Sapphires are a variety of the mineral corundum, which is composed of aluminum oxide (Al₂O₃). The color of sapphires is determined by trace elements present in the crystal structure. In the case of blue sapphires, the presence of titanium and iron is responsible for the deep blue hue. The concentration of these elements affects the intensity of the blue color, with higher concentrations producing deeper, more saturated tones.
Sapphires are formed under high-pressure and high-temperature conditions deep within the Earth's crust. They are typically found in metamorphic rocks, which are formed when existing rocks undergo transformation due to heat and pressure. Sapphires can also be found in igneous rocks, which are formed from the cooling and solidification of magma. The specific geological conditions in which sapphires form can influence their color, clarity, and overall quality.
Historically, the most famous sources of sapphires were the Kashmir region of India and Sri Lanka. Kashmir sapphires, which were mined between the late 19th and early 20th centuries, are known for their intense blue color and a unique "cornflower blue" hue. These sapphires are highly prized and can command extremely high prices at auctions. Sri Lankan sapphires, particularly those from the Ratnapura region, are also renowned for their quality and have been a significant source of sapphires for centuries.
In more recent decades, new sapphire sources have emerged. Madagascar has become a leading producer of sapphires, surpassing many traditional sources. The sapphires from Madagascar are known for their vibrant colors and high quality. Australia was also a major source of sapphires until the 1990s, when significant deposits were discovered in Madagascar. Other notable sapphire-producing countries include Thailand, Burma (Myanmar), and the United States.
The value of sapphires is influenced by their color, clarity, cut, and carat weight. High-quality sapphires with a deep blue color and excellent clarity are the most valuable. The world record price for a sapphire was set by a Kashmir sapphire that sold for $242,000 per carat, totaling over $6.74 million. This record highlights the exceptional value and desirability of certain sapphires, particularly those with rare color and origin.
Gemological Properties
Sapphires are among the hardest gemstones, second only to diamonds on the Mohs scale of mineral hardness. Sapphires score a 9 on this scale, which measures the scratch resistance of various minerals. This high hardness makes sapphires suitable for everyday wear and ensures that they can maintain their brilliance and luster over time. However, it is important to note that while sapphires are hard, they can still be fractured if struck with enough force.
The refractive index of sapphires ranges from 1.76 to 1.78, which means that they have a strong ability to bend and reflect light. This property contributes to the gemstone's brilliance and makes it visually appealing. Sapphires are also known for their high luster, which gives them a bright, glassy appearance.
In terms of color, sapphires come in a wide range of hues. While blue sapphires are the most well-known, sapphires can also be found in pink, yellow, green, orange, and purple. These color variations are referred to as "fancy sapphires." Some sapphires even exhibit a phenomenon known as "color change," where the gemstone appears to change color depending on the type of light it is viewed under. For example, certain sapphires may appear blue in daylight and purple under incandescent light.
The clarity of sapphires is another important factor in their value and appearance. Sapphires can range from completely clear to those with visible inclusions. Inclusions are natural features within the gemstone that can affect its transparency and brilliance. While some inclusions are considered flaws, others can be characteristic of the gemstone's origin and can add to its uniqueness. High-quality sapphires are those that are free of visible inclusions and have a clear, clean appearance.
Sapphires are also known for their durability, which makes them ideal for use in jewelry. They can be cut into a variety of shapes, including round, pear, oval, and princess cuts. The choice of cut can influence the gemstone's brilliance and overall appearance. Sapphires are often set in a variety of settings, including prong, bezel, and pave settings, which can enhance their beauty and provide additional security.
Symbolism and Metaphysical Beliefs
The sapphire has long been associated with wisdom, loyalty, and nobility. These symbolic meanings have contributed to its popularity as a birthstone and have influenced its use in jewelry and other cultural artifacts. In ancient times, sapphires were believed to offer protection and guidance, and they were often worn by those in positions of power or authority.
Sapphires are also associated with spiritual insight and enlightenment. In Buddhist and Hindu traditions, sapphires are believed to enhance spiritual awareness and divine connection. These beliefs have contributed to the gemstone's use in religious ceremonies and meditation practices. The sapphire's deep blue color is often seen as a reflection of the infinite and the divine, making it a symbol of spiritual depth and wisdom.
In medieval Europe, sapphires were thought to have healing properties. They were believed to cure diseases of the eye and act as an antidote to poison. While these beliefs are not supported by modern science, they reflect the deep cultural significance that sapphires held in the past.
Sapphires are also associated with love and commitment. This symbolism is particularly evident in the use of sapphires in engagement rings. The deep blue color of sapphires is often seen as a symbol of eternal love and loyalty, making them a popular choice for wedding rings and other romantic jewelry. The sapphire's association with royalty and nobility also contributes to its symbolic meaning, as it is often seen as a stone of high status and prestige.
Care and Cleaning
Due to their high hardness and durability, sapphires are relatively easy to care for compared to other gemstones. However, there are some precautions that should be taken to ensure that sapphires remain in good condition. Sapphires should be stored separately from other gemstones to prevent scratching, as even a hard gemstone can be scratched by a harder one.
When cleaning sapphires, it is important to use a gentle approach. Sapphires can be cleaned using a mild soap and warm water. A soft-bristled brush can be used to gently scrub away dirt and debris. Ultrasonic cleaners can also be used, but it is important to check that the sapphire does not have any inclusions that could be damaged by the vibrations. Steam cleaning is not recommended for sapphires, as it can potentially damage the gemstone.
Sapphires should be protected from extreme temperatures and sudden temperature changes, as these can cause the gemstone to crack or fracture. They should also be kept away from harsh chemicals, as these can damage the gemstone's surface and affect its appearance.
When wearing sapphire jewelry, it is important to avoid activities that could cause the gemstone to be struck or subjected to excessive force. While sapphires are hard and durable, they can still be chipped or fractured if struck with enough force. It is also important to remove sapphire jewelry before engaging in activities that could expose it to abrasive materials or harsh conditions.
