Discovered in Greenland in the late 1890’s, hackmanite is named for Finnish geologist Victor Hackman. It is a rare occurrence to find gem-grade hackmanite; at best, most crystals are translucent. Hackmanite is the light pink to pale violet variety of sodalite. It is a particularly unusual gem because it exhibits a special optical property known as “tenebrescence,” a type of reversible photochromism. This feature allows the gems to temporarily change color when exposed to different light forms. While hackmanite gems are usually pink to violet, the color quickly fades to gray or greenish-white in sunlight, and will slowly return to the original color after changing the light. Its tenebrescent property makes hackmanite a prized mineral for collectors.

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?
入札が行われる場合、これはその商品に対して入札者が入札する最高額となります。その後、当社のシステムは入札者に代わって自動的に入札し、最高額まで入札額を段階的に引き上げていき、最高入札者としての地位を維持します。
「自動入札」を示すアイコンがある場合、当社のシステムが入札者の最高入札額に基づいて入札者に代わって入札を行っていることを意味します。入札者が自らの入札額を上回る入札をしているように見えるかもしれませんが、これは入札者の最高額を反映するようにシステムが入札額を更新した結果にすぎません。
