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.

なぜユーザーは自分自身を上回る入札をするのでしょうか?
入札する場合、これはユーザーが製品に入札する意思のある最大金額です。その後、当社のシステムがそのユーザーに代わって自動的に入札し、最高入札者としての地位を維持するために、指定された最大値まで入札額を段階的に引き上げます。
「自動入札」を示すアイコンがある場合、システムが最高入札額に基づいてユーザーに積極的に入札していることを意味します。これは、ユーザーが自分自身を上回って入札しているように見えるかもしれませんが、ユーザーの上限を反映するためにシステムが入札を更新した結果にすぎません。
