Where The Rarest Diamonds On Earth Are Formed.

Cullinan I

The most priceless diamonds are the clearest as well, without any impurities in its physical appearance. For example, the Cullinan Diamond, named after the chairman of the mine, Thomas Cullinan, was a large gem-quality diamond weighing 3,106.75 carats (621.35 g) discovered at the Premier No. 2 mine in Cullinan, modern-day South Africa, on 26 January 1905. It was presented to King Edward VII of the United Kingdom for his 66th birthday and cut into several polished gems, the largest of which is named Cullinan I or the Great Star of Africa, and at 530.4 carats (106.08 g) it is the largest clear cut diamond in the world. The second-largest is Cullinan II or the Second Star of Africa; at 317.4 carats (63.48 g) it is the fourth-largest cut diamond in the world, and is mounted in the Imperial State Crown. Both diamonds are part of the Crown Jewels.

Lesotho Promis

The Lesotho Promise, a 603 carat (121 g) diamond stone of exceptional colour was unearthed on 22 August 2006 at the Letseng diamond mine in the mountain kingdom of Lesotho. it is the largest reported find this century and the 15th largest diamond ever found. The stone is rated ‘D’, the top colour band for diamonds. The diamond was sold at an auction on 9 October 2006 in Antwerp, Belgium, for US$12.4 million. In July 2007 the finished stones were unveiled. The largest gem cut from the crystal is a 75 carats (15.0 g) pear-shaped diamond

The Rippled Red Ribbons of SNR 0509.
Credit: NASA, ESA, and the Hubble Heritage Team (STScI/AURA); Acknowledgment: J. Hughes (Rutgers U). The ripples of supernova remnant SNR 0509-67.5, as well as the greater nebula, were imaged in unprecedented detail by the Hubble Space Telescope in 2006 and again late 2011. The red colour was recoded by a Hubble filter that left only the light emitted by energetic hydrogen. The precise reason for the ripples remains unknown, with two considered hypotheses relating them to relatively dense portions of either ejected or impacted gas. The reason for the broader red glowing ring is more clear, with expansion speed and light echoes relating it to a classic Type Ia supernova explosion that must have occurred about 400 years earlier. SNR 0509 currently spans about 23 light years and lies about 160,000 light years away toward the constellation of the dolphinfish (Dorado) in the Large Magellanic Cloud. The expanding ring carries with it another great mystery: why wasn't this supernova seen 400 years ago when light from the initial blast should have passed the Earth?

The Mohawk people are the most easterly tribe of the Haudenosaunee, or Iroquois Confederacy, an Iroquoian-speaking indigenous people of North America. The Mohawk were historically based in the Mohawk Valley in present-day upstate New York west of the Hudson River; their territory ranged north to the St. Lawrence River, southern Quebec and eastern Ontario; south to greater New Jersey and into Pennsylvania; eastward to the Green Mountains of Vermont; and westward to the border with the Iroquoian Oneida Nation's traditional homeland territory. Their current major settlements include areas around Lake Ontario and the St Lawrence River in Canada and New York.

The flag of Malaysia is composed of a field of 14 alternating red and white stripes along the fly and a blue canton bearing a crescent and a 14-point star known as the Bintang Persekutuan (Federal Star). The 14 stripes, of equal width, represent the equal status in the federation of the 13 member states and the federal territories, while the 14 points of the star represent the unity between these entities. The crescent represents Islam, the country's state religion; the blue canton symbolises the unity of the Malaysian people; the yellow of the star and crescent is the royal colour of the Malay rulers. It was first raised on 16 September 1963.
