These beliefs, rooted in ancient traditions and cultural practices, continue to influence the perception of sapphire in modern times.

Geological Formation and Sources
Sapphire is a variety of the mineral corundum, an aluminum oxide (Al₂O₃). The blue color in sapphire is caused by trace amounts of iron and titanium. The gem forms in metamorphic and igneous rocks under high-temperature and high-pressure conditions. Significant deposits are found in various parts of the world, each contributing to the global market of this coveted gemstone.
Myanmar (formerly Burma) is one of the most famous sources of sapphire, particularly for stones with a rich, velvety blue hue. The Mogok region in Myanmar is renowned for producing some of the finest sapphires in the world. Other notable sources include Sri Lanka (Ceylon), which is known for lighter, more vibrant blue sapphires, and Kashmir, a region that historically produced sapphires with a distinctive cornflower blue color, though production from this area is now limited.
Additional sources include Thailand, which is a major center for sapphire trading and treatment, and Australia, which produces sapphires in various shades of blue and green. Deposits have also been found in Madagascar, Tanzania, and the United States (specifically in Montana). The geographic diversity of sapphire sources means that the gemstone is available in a range of qualities and price points, making it accessible to a broad audience.
The formation of sapphire requires specific geological conditions. It typically occurs in aluminum-rich rocks that have undergone metamorphism, such as gneiss or schist, or in igneous rocks like basalt. The presence of trace elements during the formation process determines the color of the corundum. For blue sapphire, iron and titanium are the key chromophores. The mining process for sapphire often involves both artisanal and large-scale operations, with methods ranging from simple surface panning to more complex underground mining.
The most famous sapphire ever discovered is likely the Rockefeller Sapphire, a 62.02 carat rectangular step-cut stone that was unearthed in Myanmar (Burma). This stone exemplifies the exceptional quality that can come from this region. The gemological community continues to study sapphire deposits to understand their formation better and to discover new sources that can meet the global demand for this precious stone.
Gemological Properties
Sapphire is a member of the corundum family, which includes ruby (the red variety). Its chemical composition is aluminum oxide (Al₂O₃), with trace elements responsible for its color. On the Mohs scale of hardness, sapphire ranks a 9, making it one of the hardest natural minerals, second only to diamond. This exceptional hardness makes sapphire highly resistant to scratching and ideal for everyday jewelry, such as rings and bracelets.
The color of sapphire is its most defining characteristic. While blue is the most sought-after color, sapphire occurs in a rainbow of other colors, including pink, yellow, green, purple, and orange. These colored sapphires are often referred to by their specific hues, such as "padparadscha" for a rare pink-orange variety. The term "sapphire" by itself usually refers to the blue variety, but in gemology, any corundum that is not red (ruby) is classified as sapphire.
Clarity is another important factor in evaluating sapphire. Natural sapphires often contain inclusions, which are internal features that can affect transparency. Some inclusions, like silk (fine rutile needles), can actually enhance the stone's appearance by creating a soft, velvety texture in the blue color. However, eye-clean sapphires (those with no visible inclusions) are highly valued and command premium prices.
Cut is crucial for maximizing a sapphire's beauty. Common cuts for sapphire include oval, cushion, round, and emerald cuts. The cut must be expertly executed to bring out the best color and brilliance in the stone. Carat weight significantly influences price, with larger sapphires becoming exponentially more expensive per carat, especially for high-quality stones.
Treatments are common in the sapphire market to enhance color and clarity. The most widely accepted treatment is heat, which can intensify the blue color and remove some inclusions. Heating is a permanent treatment and is generally disclosed by reputable dealers. Other treatments, such as diffusion (adding color to the surface) or filling fractures, are less common and can significantly affect the stone's value if not properly disclosed. Buyers should always inquire about the treatment status of a sapphire to understand its value and care requirements fully.
The following table summarizes the key gemological properties of blue sapphire as described in the sources:

|---|---|
| Mineral Family | Corundum |
| Chemical Formula | Al₂O₃ (Aluminum Oxide) |
| Hardness (Mohs Scale) | 9 |
| Color | Blue (trace elements: Iron, Titanium); also occurs in pink, yellow, green, etc. |
| Common Cuts | Oval, cushion, round, emerald |
| Typical Inclusions | Silk (rutile needles), crystals, fingerprints |
| Common Treatments | Heating (to enhance color) |

Care and Cleaning
Due to its exceptional hardness (9 on the Mohs scale), sapphire is a durable gemstone suitable for a wide range of jewelry applications. However, proper care is essential to maintain its beauty and longevity. The primary rule for cleaning sapphire is to avoid harsh chemicals and sudden temperature changes, which can damage the stone or its setting.
The safest method for cleaning sapphire jewelry is to use warm water, a mild dish soap, and a soft brush. Gently scrub the stone and its setting with the brush, paying attention to the back of the stone where dirt and oils can accumulate. Rinse thoroughly with clean water and dry with a soft, lint-free cloth. Ultrasonic cleaners are generally safe for untreated and heat-treated sapphires, but they should be avoided for stones with fractures or extensive inclusions, as the vibrations could cause damage. Steam cleaning is also an option for sapphires without fractures, but caution is advised for stones with oil or resin treatments, which can be damaged by heat.
Storage is another important aspect of sapphire care. When not being worn, sapphire jewelry should be stored separately from other jewelry pieces to prevent scratching. While sapphire is very hard, it can scratch other softer gemstones and metals. A soft pouch or a compartmentalized jewelry box is ideal for storage.
It is crucial to consider any treatments the sapphire has undergone. Heat-treated sapphires are stable and can be cleaned using the methods described above. However, sapphires that have been treated with fracture filling or diffusion require special care. These treatments can be sensitive to chemicals and heat, so it is best to consult a professional jeweler for cleaning instructions for such stones. When in doubt, professional cleaning by a qualified jeweler is the safest option.
For those born on September 23, wearing sapphire jewelry regularly can be a way to connect with its symbolic meanings. However, it is still advisable to remove sapphire rings and bracelets during activities that could subject the stone to hard knocks or exposure to harsh chemicals, such as gardening, cleaning, or swimming in chlorinated pools.
