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.

Very nice stone.
Why are users outbidding themselves?
When a bid is placed, this is the maximum amount a person is willing to bid for the product. Our system will then automatically bid on behalf of the bidder, incrementally increasing the bid up to the maximum to maintain their position as the highest bidder.
When there is an icon indicating 'Automatic Bid', it means our system is actively placing bids for the bidder based on their maximum bid. This may appear as if bidders are outbidding themselves, but it's simply a result of the system updating the bid to reflect the bidders maximum limit.
