Andesine is a silicate mineral, a member of the plagioclase feldspar.
The origin of Andesine gemstones is uncertain. The original source where this gem was supposedly discovered in a natural, untreated state is in the Congo, near the Nyaragongo Volcano. The source for the diffused material is the Inner Mongolia of China. Andesine was first described in 1841 for an occurrence in the Marmato mine, Marmato, Cauca,Colombia. The name is for the Andes due to its abundance in the andesite lavas in those mountains.
In the early 2000s, red and green gemstones began to be marketed under the name of 'Andesine'. After some controversy, these gemstones were subsequently discovered to have been artificially-coloured.
The color of the Andesine gemstones being produced in China is produced by subjecting the stone to diffusion treatment with copper. -

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