A blue diamond is one of the rarest and most valuable types of diamonds, known for its natural blue color, which is due to the presence of boron in its crystal structure. Blue diamonds are highly sought after by collectors and jewelers for their rarity and aesthetic appeal. One of the most famous examples is the "Hope Diamond," which is one of the largest and most well-known blue diamonds in the world.

In terms of value, blue diamonds are typically very expensive and can fetch extremely high prices at auctions. Factors like color intensity, size, clarity, and the diamond’s history play significant roles in determining its final price.
