Ametrine is a unique gemstone. The stone comes from two types of quartz being mixed together: amethyst and citrine. As you may have guessed, the name is actually a combination of the two stones that ametrine derives from.
The color of ametrine is a mixture of yellow citrine and purple amethyst blends. Other names for the ametrine gemstone include trystine or bolivianite. The latter name comes from the fact that just about all ametrine mined today is unearthed in Bolivia

Warum überbieten sich Nutzer selbst?
Bei Abgabe eines Gebotes handelt es sich um den Höchstbetrag, den ein Nutzer für das Produkt zu bieten bereit ist. Unser System bietet dann automatisch im Namen dieses Benutzers und erhöht das Gebot schrittweise, um seine Position als Höchstbietender bis zum angegebenen Höchstbieten zu halten.
Wenn das Symbol „Automatisches Gebot“ angezeigt wird, bedeutet dies, dass unser System aktiv Gebote für den Benutzer auf der Grundlage seines Höchstgebots abgibt. Dies mag so aussehen, als ob die Nutzer sich selbst überbieten würden, aber es liegt einfach daran, dass das System das Gebot aktualisiert, um das Höchstlimit des Nutzers widerzuspiegeln.
