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]

¿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.
