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.

Zašto korisnici nadmašuju same sebe?
Kada se postavi ponuda, to je najveći iznos koji je osoba spremna ponuditi za proizvod. Naš sustav će zatim automatski licitirati u ime ponuditelja, postupno povećavajući ponudu do maksimuma kako bi zadržao svoju poziciju ponuditelja najviše ponude.
Kada postoji ikona koja označava 'Automatsku ponudu', to znači da naš sustav aktivno daje ponude za ponuditelja na temelju njihove maksimalne ponude. Ovo se može činiti kao da ponuditelji sami sebe nadmašuju, ali to je jednostavno rezultat ažuriranja ponude sustava kako bi odražavala maksimalno ograničenje ponuditelja.
