Sapphire, the recognized birthstone of September, holds a prominent place in the world of gemstones, celebrated for its beauty, durability, and rich history. While most commonly associated with a deep, regal blue, sapphire actually encompasses a spectrum of colors, each carrying its own unique symbolism and appeal. This article delves into the fascinating world of sapphire, exploring its geological origins, historical significance, gemological properties, and the enduring lore that surrounds this captivating gem.
History and Lore
Sapphires have been treasured for millennia, their allure captivating civilizations across the globe. In ancient Persia, the sky was believed to be painted blue by the reflection of these gems. Ancient Greeks and Romans, including kings and queens, adorned themselves with sapphires, believing the stones offered protection from harm and envy, and attracted divine favor. The gem was considered a symbol of power and good fortune.
During the Middle Ages, sapphires held a special significance for the clergy, representing Heaven and symbolizing faith and piety. Beyond their religious connotations, medieval Europeans attributed healing properties to sapphires, believing they could cure plague boils, alleviate eye ailments, and even serve as an antidote to poison. Ancient Persians even held the belief that the earth rested upon a giant sapphire, responsible for the blue hue of the sky.
Throughout history, sapphire has been associated with sincerity, truth, faithfulness, and nobility. Its enduring appeal has cemented its status as a meaningful and highly valued gemstone, continuing to carry a sense of wisdom and protection to this day.
Geological Formation and Sources
Sapphire is a variety of the mineral corundum, an aluminum oxide (Al2O3) with a hexagonal crystal structure. Ruby, the red variety of corundum, is its close companion. In fact, any corundum that isn’t red is classified as sapphire. The vibrant colors of sapphire arise from trace amounts of elements like iron, titanium, and chromium within the crystal lattice. Iron and titanium contribute to the blue hues, while chromium is responsible for pink and yellow shades. A combination of these elements can result in purple sapphires.
Sapphires are found in various geological environments, often forming in metamorphic and igneous rocks. Primary deposits occur in basalts and other volcanic rocks, while secondary deposits are found in alluvial gravels and riverbeds.
Significant sapphire mining locations are found worldwide. Sri Lanka, Myanmar (formerly Burma), Madagascar, Thailand, and Australia are renowned for their sapphire production. Notably, Kashmir, a mountainous region in northern India bordering Pakistan, is famed for its exceptionally prized “Kashmir blue” sapphires, considered among the most valuable in the world due to their rarity and unique color. The United States also boasts sapphire deposits, with Montana being a prominent source, and is officially recognized as the state gemstone of both Montana and Queensland, Australia.
Gemological Properties
Sapphire is renowned for its exceptional hardness, ranking 9 on the Mohs scale, making it one of the most durable gemstones. This hardness contributes to its suitability for everyday wear. While typically thought of as blue, sapphires exhibit a remarkable range of colors, including pink, yellow, green, purple, and white. The only color not found in sapphire is red, which is reserved for ruby.
The most expensive sapphires are often cornflower blue, particularly those originating from Kashmir. A rare pink-orange variety, known as Padparadscha sapphire, is also highly sought after, symbolizing creativity and passion.
