Spinel crystallizes in the isometric system; common crystal forms are octahedra, usually twinned. It has an imperfect octahedral cleavage and a conchoidal fracture. Its hardness is 8, its specific gravity is 3.5–4.1, and it is transparent to opaque with a vitreous to dull luster. It may be colorless, but is usually various shades of pink, rose, red, blue, green, yellow, brown, black, or (uncommon) violet. There is a unique natural white spinel, now lost, that surfaced briefly in what is now Sri Lanka. Some spinels are among the most famous gemstones; among them are the Black Prince’s Ruby and the “Timur ruby” in the British Crown Jewels, and the “Côte de Bretagne”, formerly from the French Crown jewels. The Samarian Spinel is the largest known spinel in the world, weighing 500 carats (100 g).
The transparent red spinels were called spinel-rubies or balas rubies. In the past, before the arrival of modern science, spinels and rubies were equally known as rubies. After the 18th century the word ruby was only used for the red gem variety of the mineral corundum and the word spinel came to be used. “Balas” is derived from Balascia, the ancient name for Badakhshan, a region in central Asia situated in the upper valley of the Panj River

¿Por qué los usuarios se superan a sí mismos?
Cuando se realiza una oferta, esta es la cantidad máxima que un usuario está dispuesto a ofertar por el producto. Luego, nuestro sistema ofertará automáticamente en nombre de ese usuario, aumentando gradualmente la oferta para mantener su posición como el mejor postor, hasta el máximo especificado.
Cuando hay un ícono que indica "Oferta automática", significa que nuestro sistema está realizando ofertas activamente para el usuario en función de su oferta máxima. Esto puede parecer como si los usuarios se estuvieran superando a sí mismos, pero es simplemente el resultado de que el sistema actualiza la oferta para reflejar el límite máximo de los usuarios.
