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 fatta un'offerta, questo è l'importo massimo che una persona è disposta a offrire per il prodotto. Il nostro sistema farà quindi automaticamente un'offerta per conto dell'offerente, aumentando gradualmente l'offerta fino al massimo per mantenere la sua posizione di miglior offerente.
Quando c'è un'icona che indica "Offerta automatica", significa che il nostro sistema sta attivamente piazzando offerte per l'offerente in base alla sua offerta massima. Questo potrebbe sembrare come se gli offerenti stessero superando se stessi, ma è semplicemente il risultato del sistema che aggiorna l'offerta per riflettere il limite massimo degli offerenti.
