History and Lore
Sapphires have been cherished for millennia, with their allure documented in the annals of ancient civilizations. In ancient Greece and Rome, sapphires were believed to have protective qualities, shielding the wearer from harm and promoting clarity of thought. The gemstone was also associated with divine favor and was often used in religious and royal contexts. In medieval Europe, sapphires were thought to be a symbol of heavenly wisdom and were worn by clergy and nobility alike. The gemstone was also believed to promote faithfulness in marriage and was often set in engagement rings.
In the Middle East, sapphires were considered to be the gemstone of the sky and were believed to be created from the light of the stars. In India, sapphires were revered for their supposed ability to bring good fortune and were often used in ceremonial and royal regalia. The gemstone also held significance in the Far East, where it was believed to bring wisdom and spiritual insight.
The sapphire’s role as a birthstone is more modern in origin, with the tradition of assigning gemstones to specific months beginning in the 13th century. The practice was formalized in the 19th and 20th centuries, with various sources, including the American National Association of Jewelers, contributing to the standardization of birthstone assignments. Sapphires were assigned to September, and their association with truth, sincerity, and constancy has continued to be emphasized in modern interpretations of the gemstone’s symbolism.
In contemporary culture, sapphires are often associated with royalty and high fashion. The engagement ring of the British royal family, famously worn by both Princess Diana and Kate Middleton, features a sapphire center stone. This has further cemented the gemstone’s status as a symbol of elegance and enduring love. In addition to its royal associations, sapphires are also popular in contemporary jewelry design, with many designers incorporating the gemstone into both traditional and avant-garde pieces.
Geological Formation and Sources
Sapphires are formed deep within the Earth’s crust under high pressure and temperature conditions. They are a type of corundum, a mineral composed of aluminum oxide (Al₂O₃), and their color is determined by trace elements present during their formation. The most common sapphires are blue, and this coloration is primarily due to the presence of iron and titanium. Other elements, such as chromium and vanadium, can produce sapphires in shades of pink, purple, and even colorless.
The formation of sapphires typically occurs in metamorphic rocks, particularly those that have undergone regional metamorphism. These rocks are subjected to intense heat and pressure, which facilitates the crystallization of corundum. Sapphires can also form in igneous rocks, particularly in certain types of basalt and syenite. In addition to natural sapphires, synthetic sapphires can be created in laboratories through processes such as the Czochralski method and flame fusion. These synthetic stones have the same chemical composition and physical properties as their natural counterparts but are produced under controlled conditions.
Natural sapphires are found in several countries around the world. Sri Lanka is one of the most well-known sources of sapphires, producing high-quality stones in a variety of colors. Other notable sources include Myanmar, Thailand, Madagascar, and Australia. Each location can produce sapphires with distinct color characteristics and inclusions, which are often used as identifiers for the gemstone’s origin. The presence of certain inclusions, such as rutile needles or silk-like structures, can also affect the stone’s appearance and value.
In addition to natural sapphires, lab-grown sapphires are also used in jewelry. These stones are created through a process that replicates the natural conditions under which sapphires form. Lab-grown sapphires are chemically identical to natural sapphires and offer a more sustainable and ethical alternative to mined stones. They are often used in jewelry design, particularly in pieces that emphasize ethical sourcing and environmental responsibility.
Gemological Properties
Sapphires are among the hardest gemstones, with a rating of 9 on the Mohs scale of mineral hardness. This makes them highly durable and suitable for use in everyday jewelry, including rings and bracelets. Their hardness is due to their crystalline structure, which is composed of tightly packed aluminum oxide molecules. In addition to their hardness, sapphires are also resistant to scratches and abrasions, making them ideal for use in wearable art.
The refractive index of sapphires ranges from 1.76 to 1.78, which means that they have a relatively high level of brilliance and fire. This optical property contributes to their visual appeal, as sapphires can display a range of colors depending on the angle at which they are viewed. The presence of inclusions can also affect the stone’s appearance. Some inclusions, such as rutile needles or silk-like structures, can enhance the stone’s beauty by creating a star effect, a phenomenon known as asterism. These inclusions can also be used to determine the gemstone’s origin.
Sapphires are available in a wide range of colors, a fact that is attributed to the trace elements present during their formation. The most well-known sapphires are blue, but they can also appear in shades of pink, yellow, green, and even colorless. The term "fancy sapphires" is used to describe sapphires that are not blue. The color of a sapphire can affect its value, with certain colors being more highly prized than others. For example, Kashmir sapphires, which have a unique cornflower blue color and a velvety appearance, are considered some of the most valuable sapphires in the world.
The clarity of sapphires can vary depending on the presence of inclusions. Some sapphires are completely clear, while others may contain visible inclusions. These inclusions can be used as identifiers for the gemstone’s origin and can also affect its value. In general, sapphires with fewer inclusions are more valuable, but some inclusions can enhance the stone’s beauty and character.
Sapphires are typically cut into a variety of shapes, including round, oval, cushion, and pear. The choice of cut depends on the stone’s shape, clarity, and the desired outcome. Sapphires can also be cut into raw or natural forms, particularly in pieces that emphasize the raw beauty of the gemstone. The cut of a sapphire can affect its brilliance and fire, with well-cut stones displaying a greater level of light return.
Symbolism and Metaphysical Beliefs
Sapphires have long been associated with wisdom, truth, and spiritual insight. In ancient times, they were believed to have protective qualities and were often worn as talismans. The gemstone was also associated with the divine and was believed to bring the wearer closer to the heavens. In medieval Europe, sapphires were thought to promote faithfulness in marriage and were often used in engagement rings. The gemstone was also believed to enhance the wearer’s ability to think clearly and make sound decisions.
In addition to their protective qualities, sapphires were also believed to promote emotional balance and inner peace. They were associated with the throat chakra, which is believed to be the center of communication and self-expression. Sapphires were thought to help the wearer express themselves more effectively and to communicate their thoughts and feelings with clarity and confidence. This made them particularly valuable for individuals in positions of leadership or public speaking.
Sapphires were also believed to have healing properties. In traditional medicine, they were used to treat ailments of the throat, eyes, and heart. They were also believed to have a calming effect on the mind and to help reduce stress and anxiety. In modern times, sapphires are still used in alternative medicine and are believed to have a range of healing properties, including the ability to improve circulation and promote mental clarity.
As the September birthstone, sapphires are associated with the themes of truth, sincerity, and constancy. They are believed to help the wearer remain true to themselves and to their values, even in the face of adversity. Sapphires are also believed to promote loyalty and to strengthen relationships, making them a popular choice for engagement rings and other pieces of sentimental jewelry.
September Birthstone Jewelry Sets
Sapphire jewelry sets are a popular choice for those born in September, as well as for those who appreciate the gemstone’s beauty and symbolism. These sets often include rings, necklaces, and earrings, each of which can be designed to highlight the sapphire’s unique qualities. The design of sapphire jewelry can vary widely, from traditional and elegant to modern and avant-garde, depending on the preferences of the wearer and the artistic vision of the jeweler.
One of the most popular forms of September birthstone jewelry is the sapphire ring. These rings can be designed in a variety of styles, including solitaire, halo, and cluster settings. The choice of setting depends on the size and shape of the sapphire, as well as the desired aesthetic. Some rings are set with a single large sapphire, while others may feature multiple smaller stones arranged in a pattern. The metal used in sapphire rings can also vary, with popular choices including white gold, yellow gold, rose gold, and silver.
Sapphire necklaces are another popular form of September birthstone jewelry. These necklaces can be designed with a single sapphire pendant or with a chain that features multiple sapphire stones. The choice of chain length and style depends on the desired look and the occasion for which the necklace will be worn. Sapphire pendants can also be designed to be removable, allowing the wearer to customize their jewelry collection by swapping out pendants or pairing them with other pieces.
Sapphire earrings are also a popular choice, particularly for those who prefer more subtle forms of jewelry. These earrings can be designed as studs, hoops, or dangle styles, depending on the desired effect. The size and shape of the sapphire used in earrings can also vary, with some earrings featuring small, delicate stones and others featuring larger, more prominent stones. The metal used in sapphire earrings can also vary, with popular choices including silver, gold, and platinum.
In addition to traditional sapphire jewelry, there are also alternative September birthstone jewelry sets that feature the gemstone Lapis Lazuli.

Care and Cleaning
Sapphires are among the hardest gemstones, with a rating of 9 on the Mohs scale of mineral hardness. This makes them highly durable and resistant to scratches and abrasions. However, despite their hardness, sapphires can still be damaged if exposed to certain conditions. For example, sapphires can be susceptible to thermal shock, which can cause them to crack or fracture if they are subjected to sudden temperature changes. They can also be affected by strong chemicals, which can dull their luster or even cause damage to the stone.
To care for sapphire jewelry, it is important to avoid exposing the gemstone to harsh chemicals, such as bleach or ammonia. These substances can be found in household cleaners, swimming pools, and even some types of perfume and cologne. It is also important to avoid exposing sapphire jewelry to high temperatures, such as those found in ovens, microwaves, or direct sunlight for extended periods. If a sapphire is suspected of having inclusions that could be affected by heat, it is best to avoid exposing it to high temperatures altogether.
Cleaning sapphire jewelry can be done using a soft cloth and a mild detergent, such as dish soap. A soft-bristled brush can also be used to gently scrub the stone, particularly in areas where dirt or debris may have accumulated. It is important to avoid using ultrasonic cleaners or steam cleaners, as these can be too harsh for sapphire jewelry and may cause damage to the stone or its setting. After cleaning, sapphire jewelry should be dried with a soft, lint-free cloth to prevent water spots and to restore its luster.
When storing sapphire jewelry, it is important to keep it in a cool, dry place away from direct sunlight and sources of heat. Sapphires should also be stored separately from other gemstones, particularly those with a lower hardness, to prevent scratches or abrasions. A soft pouch or a jewelry box with individual compartments can be used to protect sapphire jewelry from dust, dirt, and damage.
Regular inspections of sapphire jewelry are also recommended to ensure that the stone remains secure in its setting. Over time, the metal setting can wear down or become loose, which can cause the sapphire to become loose or even fall out. If a sapphire is found to be loose or if the setting appears to be damaged, it is best to have the jewelry inspected and repaired by a professional jeweler.
