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

Why are users outbidding themselves?
When a bid is placed, this is the maximum amount a person is willing to bid for the product. Our system will then automatically bid on behalf of the bidder, incrementally increasing the bid up to the maximum to maintain their position as the highest bidder.
When there is an icon indicating 'Automatic Bid', it means our system is actively placing bids for the bidder based on their maximum bid. This may appear as if bidders are outbidding themselves, but it's simply a result of the system updating the bid to reflect the bidders maximum limit.
