Sapphire Gemstone Description
Sapphire is a precious gemstone from the corundum mineral family, composed of aluminum oxide (Al₂O₃). While it is most famous for its deep blue color, sapphire occurs in a variety of other hues, except red (which is classified as ruby).
Key Characteristics of Sapphire
• Color:
• The most sought-after sapphire is deep blue.
• It also appears in pink, yellow, green, purple, orange, white, and even color-changing varieties.
• Padparadscha sapphire, a rare pink-orange variety, is one of the most valuable.
• Hardness: 9 on the Mohs scale (extremely durable, second only to diamond).
• Luster: Vitreous (glassy) and highly reflective.
• Clarity: High-quality sapphires are typically eye-clean, though some may have minor inclusions such as rutile silk.
• Refractive Index: 1.76 – 1.78, giving it exceptional brilliance.
• Formation: Found in igneous, metamorphic, and alluvial deposits.
• Sources:
• Myanmar (Burma) – Produces some of the finest blue sapphires.
• Sri Lanka – Known for high-quality blue and padparadscha sapphires.
• Kashmir (India) – Famous for velvety blue sapphires (extremely rare).
• Madagascar, Thailand, Australia, and Montana (USA) – Other key sapphire sources.
Special Types of Sapphire
• Padparadscha Sapphire: A rare pinkish-orange variety highly prized for its unique color.
• Star Sapphire: Displays a six-rayed star effect (asterism) due to aligned rutile inclusions.
• Color-Change Sapphire: Shifts between blue and purple depending on lighting conditions.
Treatment & Enhancements
• Heat Treatment: Commonly used to enhance color and clarity.
• Unheated Sapphires: Extremely rare and highly valuable.
• Beryllium Treatment: Used to create vibrant orange and yellow hues.
Uses & Value
• A top choice for fine jewelry, including rings, necklaces, and royal crowns.
• The birthstone for September and a traditional engagement ring choice (e.g., Princess Dianaâ€TMs sapphire ring).
• Symbolizes wisdom, loyalty, and protection.
Would you like a comparison between sapphire and another gemstone, such as spinel or tanzanite?
