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.

为什么用户出价高于自己？
当有人出价时，这是某人愿意为产品出价的最高金额。然后我们的系统将自动代表竞标者出价，逐步提高出价直至最高价，以保持其最高出价者的地位。
当出现“自动出价”图标时，表示我们的系统正在根据出价者的最高出价为其出价。这可能看起来像是出价者在出价高于自己，但这只是系统更新出价以反映出价者的最高限额的结果。
