Natural blue diamonds are some of the rarest and most valuable gemstones in the world. Their stunning blue color comes from trace amounts of boron within the diamondâ€TMs crystal structure. Hereâ€TMs a quick breakdown of what makes them special:
Key Facts about Natural Blue Diamonds
• Color Source: Boron atoms trapped during formation cause the blue hue. The more boron, the deeper the blue.
• Rarity: Extremely rare—most blue diamonds come from only a few mines, like the Cullinan Mine in South Africa or the Golconda mines in India (historically).
• Famous Examples:
• Hope Diamond (45.52 carats, deep blue, cursed legend attached)
• Blue Moon of Josephine (12.03 carats, vivid blue, sold for over $48 million)
• Price: Often fetch millions per carat, especially if graded “fancy vivid blue†by the GIA (Gemological Institute of America).
• Treated vs. Natural: Some diamonds are treated to appear blue—natural ones are far more valuable and must be certified.

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。
