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.

Warum überbieten sich Nutzer selbst?
Wenn ein Gebot abgegeben wird, ist dies der Höchstbetrag, den eine Person für das Produkt bieten möchte. Unser System bietet dann automatisch im Namen des Bieters und erhöht das Gebot schrittweise bis zum Höchstbetrag, um die Position des Höchstbietenden beizubehalten.
Wenn ein Symbol mit der Aufschrift „Automatisches Gebot“ angezeigt wird, bedeutet dies, dass unser System aktiv Gebote für den Bieter basierend auf seinem Höchstgebot abgibt. Dies kann so aussehen, als würden die Bieter sich selbst überbieten, aber es ist lediglich das Ergebnis der Aktualisierung des Gebots durch das System, um das Höchstlimit des Bieters widerzuspiegeln.
