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.

Why are users outbidding themselves?
When a bid is placed, this is the maximum amount a person is willing to bid for the product. Our system will then automatically bid on behalf of the bidder, incrementally increasing the bid up to the maximum to maintain their position as the highest bidder.
When there is an icon indicating 'Automatic Bid', it means our system is actively placing bids for the bidder based on their maximum bid. This may appear as if bidders are outbidding themselves, but it's simply a result of the system updating the bid to reflect the bidders maximum limit.
