Blue Diamonds sets record for price-per-carat sale

Sotheby’s auction creates a new global record for highest price of any blue diamond as well as sets a record for price-per-carat for any diamond which is $3.3 million per carat. A presale estimated $10 to $15 million blue diamond ended up at whooping total amount of $32,645,000 after intense bidding from even prospective buyers. The gem eventually went to a Hong Kong private collector’s inventory. Hong Kong collectors are constantly active in the world jewelry market.

Blue-Diamonds

The vivid blue diamond is of 9.75 carat with exceptional purity of the blue with no other colors. It also has the very high clarity to all other blue diamonds which contain imperfections due to crystal formation.

The gem belongs to the collection of heiress Rachel “Bunny” Mellon, who died earlier this year. She was the widow of philanthropist and horse breeder Paul Mellon. Sotheby’s New York continues the auctions of the Mellon Collection through Sunday.

118-mn-yr-old dinosaur tracks found in African diamond mine

Researchers have found nearly 70 tracts of 118 million year old dinosaur, crocodile and large mammal in the Catoca mine in Angola. It also show a mysterious raccoon-sized animal, during a time when most were no larger than a rat. They also found 18 sauropod tracks, with a preserved skin impression.

All the tracks were found in a small sedimentary basin, formed about 118 million years ago, during the Early Cretaceous, in the crater of a kimberlite pipe, researchers said.

Footprints

“These tracks are unique because they are the first vertebrate fossils ever found from the inlands of Angola,” said researcher Marco Marzola of the PaleoAngola Project. “All the other vertebrate fossils on Angola were found on the coastline.”

The Catoca Diamond Mine, the world’s fourth largest diamond mine, had stopped mining for almost eight months to preserve the findings and make the study possible.

The tracks are sent to the Universidade Nova de Lisboa and Southern Methodist University in Dallas, Texas, for preservation and study. Soon they will return to Angola. “Everything belongs to that nation and its heritage,” Marzola said. “This is very important to underline.”
