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

Perché gli utenti superano se stessi?
Quando viene effettuata un'offerta, questo è l'importo massimo che un utente è disposto a offrire per il prodotto. Il nostro sistema farà quindi automaticamente un'offerta per conto di quegli utenti, aumentando in modo incrementale l'offerta per mantenere la loro posizione di miglior offerente, fino al massimo specificato.
Quando è presente un'icona che indica "Offerta automatica", significa che il nostro sistema sta attivamente facendo offerte per l'utente in base alla sua offerta massima. Potrebbe sembrare che gli utenti stiano superando l'offerta, ma è semplicemente il risultato dell'aggiornamento dell'offerta da parte del sistema in modo da riflettere il limite massimo degli utenti.
