Christie's auction house in central London displayed the world's largest flawless D-coloured diamond on Tuesday, ahead of its sale at auction. The rare type 2A, flawless, emerald-cut diamond, weighs 163.4 carats and is in D colour, one of the finest colours of diamond. The incredibly rare interally flawless diamond was found last year in Angola and is expected to go to auction in Geneva on November 10.
The 'Sleeping Lion Pearl' is set to be sold at auction for the first time in 240 years at the Venduehuis in The Hague. Previously owned by Catherine the Great, the pearl had been lost, found, survived the Russian Revolution of 1917 and is now estimated to be worth €540,000.
Three sea turtles were released back into the wild from a beach in Samandag, in the Turkish province of Hatay, on Thursday, after undergoing treatment for injuries at a local turtle rescue centre. A Green turtle (Chelonia mydas) and two loggerhead turtles (Caretta caretta) were carried in containers to the coast, where they were then let loose and allowed to walk off and into the waves of the Mediterranean Sea.
China switched on the world's largest floating solar farm, located a small distance from the city of Huainan in the eastern Anhui province, in May. Local authorities decided to implement the project after a coal mining operation flooded, leading to questions about how best to use the site. The floating solar farm itself was built by Chinese manufacturer Sungrow Power Supply, at its full capacity of 40 megawatts, the plant can provide electricity for more than 15,000 homes.
This array of 149 Xenon short-arc lamps is called Synlight, and it's designed to be an artificial sun. Invented by the German Aerospace Centre, or DLR, Synlight can produce up to 10,000 times the intensity of natural sunlight experienced on Earth. Researchers and scientists turned on their machine for Ruptly in Juelich on Monday. The Synlight array measures 45 by 52 feet but all the powerful bulbs are designed to concentrate their light radiation on a small space which measures just 8 inches by 8 inches. Its inventors claim that the synthetic sun can generated temperatures up to 3000 degrees Celsius and beyond. Synlight was created with a specific purpose in mind. Hydrogen fuel, considered by many to be the fuel of the future because it emits no carbon when burned, is derived by breaking water down into its base atoms. However, this process requires a huge amount of heat energy. Synlight is meant to power the reaction to obtain hyrdogen fuel in a way that uses as little fossil fuels as possible. The high power array also has potential uses in other fields as well, including scientific research and commercial applications which require an intense source of heat. The project cost about 3.5 million euro to buid, funding which was provided by the German government and automaker BMW.
This dazzling and breathtaking precious stone is called the Pink Star Diamond, and it may well prove to be the world's most expensive cut diamond after it goes up for auction. The natural diamond was initially mined by diamond giant De Beers in Botswana and 1999 and weighed an astounding 132.5 carats when it first came out of the ground. However, it is not even close to the largest gem quality rough diamond. That award goes to the Cullinan Diamond, which weighed over 3100 carats when first mined in 1905. Although the Pink Star is set to be the most valuable cut diamond ever sold at auction, two other diamonds still have a higher estimated value: the De Beers Centenary Diamond, with an estimated value of $100 millions and the Hope Diamond, estimated at $350 million.
