This diversity reflects the evolution of birthstone lists over time, yet sapphire’s prominence in the modern list is a testament to its enduring appeal and established value.
Geological Formation and Sources: The Corundum Family
Sapphire belongs to the corundum family, a group of minerals composed of aluminum oxide (Al₂O₃). The same mineral family gives us the ruby; the defining difference is color. While red corundum is classified as a ruby, all other colors of corundum, including the classic blue sapphire, are designated as sapphires. This gemological classification is crucial for understanding the stone’s identity and value.
The formation of sapphire is a testament to the immense geological forces of our planet. Corundum crystallizes under high temperatures and pressures, typically in metamorphic rocks like marble or in certain igneous rocks such as basalt. The presence of trace elements during its formation is what imparts sapphire’s diverse color palette. For example, iron and titanium are responsible for the coveted blue hues, while other trace elements can produce yellow, green, pink, or even colorless varieties.
Sapphire mining is a global endeavor, with significant deposits found in various regions around the world. The sources mentioned in the provided materials highlight key locations known for producing high-quality sapphires. Myanmar (formerly Burma) is a historic source, renowned for its vibrant blue sapphires. The famous Rockefeller Sapphire, a 62.02-carat rectangular step-cut stone, was unearthed in Myanmar, underscoring the country’s importance in the gem’s history.
Other notable sources include Sri Lanka (Ceylon), which has been a traditional source for sapphires for centuries, and Kashmir, a region historically known for producing exceptionally fine, velvety blue sapphires. Madagascar has emerged as a significant modern source, contributing a variety of sapphire colors to the global market. Australia is also a key producer, particularly of darker blue and greenish-blue sapphires. In the United States, deposits have been found in Montana, offering a domestic source for this cherished gem.
The geographical diversity of sapphire sources not only affects the stone’s availability but also influences its characteristics. Sapphires from different locations can exhibit slight variations in hue, saturation, and clarity, a fact that gemologists and collectors closely study. This global distribution ensures that sapphire remains accessible, though the finest specimens from historically significant locations command premium prices.
Gemological Properties: Science of the Sapphire
Understanding sapphire requires a grasp of its fundamental gemological properties. These scientific characteristics define its durability, beauty, and value.
Hardness and Durability: Sapphire is exceptionally hard, rating a 9 on the Mohs scale of mineral hardness.

These include: * Blue Sapphire: The classic variety, ranging from light to deep royal blue. * Fancy Color Sapphires: These include pink, yellow, green, and even colorless (white) sapphires. * Padparadscha: A rare and highly prized sapphire with a delicate pink-orange hue, often described as "sunset" or "lotus" colored. * Star Sapphire: Some sapphires exhibit an optical phenomenon called asterism, where a six-rayed star appears to glide across the surface of a cabochon-cut stone. This is caused by needle-like inclusions of the mineral rutile (titanium dioxide) aligned in specific directions within the crystal.
Clarity and Cut: Like most gemstones, sapphires are evaluated for clarity. Inclusions are common in natural sapphires and can be used to identify their origin and authenticity. While flawless sapphires are rare and valuable, some inclusions are accepted, especially if they do not detract from the stone’s beauty or durability. Sapphires are cut in a variety of shapes to maximize color and brilliance, including oval, cushion, round, and emerald cuts. The cut is crucial for revealing the stone’s best color and light performance.
Refractive Index and Specific Gravity: Sapphire has a refractive index ranging from approximately 1.76 to 1.77, which contributes to its brilliance when properly cut. Its specific gravity typically falls between 3.95 and 4.03, a measure used by gemologists to help identify the stone.
