Ametrine, also known as trystine or by its trade name as bolivianite, is a naturally occurring variety of quartz . It is a mixture of amethyst and citrine with zones of purple and yellow or orange. Almost all commercially available ametrine is mined Bolivia although there are deposits being exploited in Brazil and India
The colour of the zones visible within ametrine is due to differing oxidation states iron within the crystal. The different oxidation states occur due to there being a temperature gradient across the crystal during its formation.
Artificial ametrine can be created by differential heat treatment of amethyst.
Most ametrine in the low price segment can surely be assumed to stem from synthetic material. Since 1994 a Russian laboratory has perfected the industrial production of bicolored quartz crystals that are later irradiated to bring out the typical ametrine colors. Green-yellow or golden-blue ametrine does not exist naturally.

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.
