Tourmaline is extremely popular among collectors and is a well-known gemstone. It is the most multicolored mineral type known, occurring in virtually every color of the spectrum. Individual stones are often multicolored and are unsurpassed in their beauty. The color of some Tourmaline can be enhanced through Heat treatment. Some greenish stones can be made deep green, some brownish-red stones can be made red, and some light pink stones can be made colorless through heating. Tourmaline has many interesting optical properties. Many green and blue specimens are strongly pleochroic. Indicolite is one of the most valuable and collectible of all elbaite Tourmalines, with hues spanning from lighter to deep, intense blues. Cutting indicolite can be a task for even the most skilled of cutters, as it is strongly Pleochroic and appears darker when viewed down the crystal. This factor must be taken into consideration when cutting, as a loss of transparency and brilliance can occur in darker specimens.

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.
