Tanzanite Gemstone :
Tanzanite is the blue and violet variety of the mineral zoisite (a calcium aluminium hydroxyl sorosilicate), caused by small amounts of vanadium.[3] Tanzanite belongs to the epidote mineral group. Tanzanite is only found in Tanzania, in a very small mining area (approximately 7 km (4.3 mi) long and 2 km (1.2 mi) wide)[4] near the Mererani [sw] Hills.[5]
Tanzanite is noted for its remarkably strong trichroism, appearing alternately blue, violet and burgundy depending on crystal orientation.[6] Tanzanite can also appear differently when viewed under different lighting conditions. The blues appear more evident when subjected to fluorescent light and the violet hues can be seen readily when viewed under incandescent illumination. In its rough state tanzanite is colored a reddish brown to clear, and it requires heat treatment to remove the brownish "veil" and bring out the blue violet of the stone.[7]

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