SPHENE is a very rare brilliant yellowish-green, green, orange or brown gemstone with a high luster, also known as "titanite" due to its titanium content. The name "sphene" comes from the Greek word, "sphen", meaning "wedge", which alludes to the formation of its crystals. Due to its high dispersion, when brilliant-cut, sphene can exhibit a fire similar to that of diamond.
Sphene has been known since 1787 and was named according to its titanium content in 1795 by Martin Klaproth. In 1801, it was given the name "sphene" by French mineralogist, Rene Just Hauy. In 1982, the International Mineralogical Association Commission on New Minerals and Mineral Names (CNMMN) decided to use the name "titanite" rather than "sphene". However, both "sphene" and "titanite" continue to be recognized in mineralogy circles, and sphene is the most frequently used gemology term.

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.
