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

Waarom overbieden gebruikers zichzelf?
Wanneer er wordt geboden, is dit het maximale bedrag dat een gebruiker bereid is te bieden op het product. Ons systeem zal dan automatisch namens die gebruiker bieden, waarbij het bod stapsgewijs wordt verhoogd om hun positie als hoogste bieder te behouden, tot aan het opgegeven maximum.
Als er een pictogram is dat 'Automatisch bieden' aangeeft, betekent dit dat ons systeem actief biedingen plaatst voor de gebruiker op basis van hun maximumbod. Dit kan lijken alsof gebruikers zichzelf overbieden, maar het is gewoon het gevolg van het feit dat het systeem het bod bijwerkt om de maximumlimiet van de gebruiker weer te geven.
