Tourmaline ( /ˈtʊərməlɪn/, -/iːn/ TOOR-mə-lin, -leen) is a crystalline boron silicate mineral compounded with elements such as aluminium, iron, magnesium, sodium, lithium, or potassium. Tourmaline is classified as a semi-precious stone and the gemstone comes in a wide variety of colors.
History[edit]
Brightly colored Sri Lankan gem tourmalines were brought to Europe in great quantities by the Dutch East India Company to satisfy a demand for curiosities and gems. At the time,[when?] it was not realised that schorl and tourmaline were the same mineral, as it was only about 1703 that it was discovered that some colored gems were not zircons.[citation needed] Tourmaline was sometimes called the “Ceylonese [Sri Lankan] Magnet” because it could attract and then repel hot ashes due to its pyroelectric properties.[2][4]
Tourmalines were used by chemists in the 19th century to polarize light by shining rays onto a cut and polished surface of the gem.[

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.
