Sapphire Description:
Sapphire is one of the most valuable and durable gemstones, known for its deep blue color but found in a variety of hues. It is a member of the corundum mineral family, composed of aluminum oxide (Al₂O₃). The presence of trace elements like iron and titanium gives sapphire its color.
Key Characteristics of Sapphire:
• Color: Most commonly deep blue, but also found in pink, yellow, green, purple, orange, white, and even color-changing varieties. Red corundum is classified as ruby.
• Hardness: 9 on the Mohs scale (extremely durable, second only to diamond).
• Luster: Vitreous (glassy) with strong brilliance.
• Clarity: High-quality sapphires are typically eye-clean, but some may have minor inclusions, such as silk-like rutile needles.
• Refractive Index: 1.76 – 1.78, contributing to its brilliance.
• Formation: Found in metamorphic, igneous, and alluvial deposits.
• Sources: Myanmar (Burma), Sri Lanka, Kashmir (India), Madagascar, Thailand, Australia, and the U.S. (Montana).
Special Types of Sapphire:
• Padparadscha Sapphire: A rare pinkish-orange variety highly prized for its unique color.
• Star Sapphire: Exhibits a six-rayed star effect (asterism) due to aligned rutile inclusions.
• Color-Change Sapphire: Shifts between blue and purple depending on lighting.
Treatment and Enhancements:
• Heat Treatment: Commonly used to improve color and clarity.
• Unheated Sapphires: Rare and highly valuable.
• Beryllium Treatment: Used to create vibrant orange or yellow hues.
Uses and Value:
• Used in high-end jewelry such as rings, necklaces, and crowns.
• September birthstone and a popular choice for engagement rings.
• Worn for symbolism—associated with 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.
