A Unique Blue Moon Diamond Now on Display at Natural History Museum

Petra Diamond Mine is a birthplace of exceptional world-know diamonds that cause a jaw-dropping effect at any auction they appear: first off, by their unique properties and, second, by their extremely high price tags. Since it would take much time to name all those notable diamonds found in Petra mine, let's focus on two latest blue diamonds that were discovered in South African's mine this year.

Early this year a 29.6-carat fancy vivid blue diamond was found and later sold at a record $25.6 million price to Cora International, the leading supplier and manufacturer of white and colored diamonds in the world. Little time passed after that when another blue diamond made headlines due to its unbelievable huge size — 122.5 carats. Petra again proved its status of the mine that produces giant gems. To give you a vivid illustration of what size that is, it's as big as a wall-nut. Taking into account its blue, it looks like it's priceless. So far the fate of the last is still unknown, while there's a follow-up story of a smaller fancy vivid blue.

Huge Blue Diamond Found at Cullinan

It seems there are no other talks in the diamond sphere but for rare blue diamond that was extracted from Cullinan mine. This is not the color that stirred the noise as far as blue diamonds are found regularly, though it less amount than white or yellow. This is the size of it that caused a wow effect.

The Petra Diamond mine 'gave birth' to a 122.52 carat blue diamond that makes this finding really significant. Petra is known as the worlds source of blue diamonds. Last year they managed to sell a 25.5 carat stone for $16.9 million, so it's hard to image how much this giant will cost. The truth is that blue diamonds are and have always been incredibly rare. Many of big blue stones have an entangled story that even adds to the price. These days jewels of this color are highly sought-after and collectable so there's hardly the sale without any blue diamonds.
