In 1988 exceptionally bright colored tourmalines were discovered in Paraíba, Brazil. It was determined that they were elbaite tourmalines and the intense coloring was due to copper. They also contained manganese and often a bit of bismuth. These stones generated great excitement and prices soon went over $20K per carat.
Soon after the original discovery, similar tourmalines were found in Brazil’s Rio Grande Do Norte state, just north of Paraíba state. This new find was also described as “paraíba tourmaline.”
In 2001, more copper colored tourmalines were discovered in Nigeria. Generally, the Nigerian gemstones were not as vivid as those from Brazil, although the range of colors did overlap. With the proper equipment, the Nigerian material can be distinguished by its lead content, which the Brazilian material lacks.
A couple years later, still more copper bearing tourmalines were discovered, this time in Mozambique. Their colors are much closer to those of the Brazilian, but their chemical composition is much more complex, with varying amounts of copper, magnesium, lead, and bismuth. A large number of these tourmalines do not contain any lead and have compositions that overlap those of the Brazilian tourmalines.Shipping Rates of DHL has been changed for these countries i.e $35 (Argentina,Bulgaria,Colombia,Egypt,Finland,Iceland,Iran,Kuwait,Madagascar,Norway,Qatar,Russian Federation,Saudi Arabia,South Africa,Turkey,Ukraine,United Arab Emirates,Zimbabwe)

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.
