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.
Would you like a comparison between sapphire and another gemstone, like tanzanite or spinel?

Nice stone, thank you
Pourquoi les utilisateurs se surenchérissent-ils ?
Lorsqu'une enchère est placée, il s'agit du montant maximum qu'une personne est prête à enchérir pour le produit. Notre système enchérira alors automatiquement au nom de l'enchérisseur, augmentant progressivement l'enchère jusqu'au maximum pour maintenir sa position de meilleur enchérisseur.
Lorsqu'une icône indiquant « Enchère automatique » apparaît, cela signifie que notre système place activement des enchères pour l'enchérisseur en fonction de son enchère maximale. Cela peut donner l'impression que les enchérisseurs se surenchérissent, mais c'est simplement le résultat de la mise à jour de l'enchère par le système pour refléter la limite maximale des enchérisseurs.
