Corvette ... The Great American Supercar

The Chevrolet Corvette is a sports car manufactured by the Chevrolet division of General Motors. The car has been produced through seven generations.

The first model, a convertible, was designed by Harley Earl and introduced at the GM Motorama in 1953 as a concept show car. Myron Scott is credited for naming the car after the type of small, maneuverable warship.
The 1954 model year vehicles could be ordered in Pennant Blue, Sportsman Red and Black, or Polo White. 3,640 were built, and sold slowly.

1956 Corvette
The 1958 Corvette received quad headlamps, bumper exiting exhaust tips and a new steering wheel. The 1959–60 model years had few changes except a decreased amount of body chrome and more powerful engine offerings.
In 1961, the rear of the car was completely redesigned with the addition of a "duck tail" with four round lights. The second generation (C2) Corvette introduced the Sting Ray. Production started for the 1963 model year and ended in 1967.
The third generation Corvette was introduced for the 1968 model year and was in production until 1982. Styling changed subtly throughout the generation until 1978 for the car's 25th anniversary.

Regular fourth generation production began on January 3, 1983. Beginning in 1985, the 230 bhp (170 kW) L98 engine with tuned port fuel injection became the standard. Chevrolet released the Grand Sport (GS) version in 1996 to mark the end of production of the C4 Corvette.
Production of the C5 Corvette began in 1997 and ended with the 2004 model year. The C5 had a top speed of 181 mph (291 km/h) and was judged by the automotive press as improved in nearly every area over the previous Corvette design.
The sixth generation-C6 was produced between 2005 and 2013. The 6.0L (364 cu in) LS2 V8 produced 400 bhp giving the vehicle a 0–60 time of under 4.2 seconds. Its top speed was 190 mph (310 km/h).
The 2015 Corvette Z06 was engineered to be lightweight and rigid with an aluminum space frame, carbon-fiber hood and removable carbon-fiber roof panel.

It was also designed to be powerful, with a supercharged 6.2L aluminum V8 engine delivering at least 625 horsepower and 635 lb.-ft. of torque. The 2015 Corvette Z06 is one of the industry’s only supercars to achieve over 600 horsepower and offer a choice of two transmissions – a 7-speed manual or an all-new paddle-shift 8-speed automatic.

Red Diamonds

Pure red diamonds devoid of secondary hues are the rarest in the world. The Argyle Diamond Mine is the only known significant source of pink and red diamonds, producing over 95% of the world's supply. In the last 30 years of mining, Argyle has found a total of nine red diamonds.

Red diamonds are so rare that there is little gemological information about them. What is known is that crystal lattice defects showing stress lamination during the diamond's formation are the cause of the red color.
The Kazanjian Red Diamond, One of the three known red diamonds weighing more than 5 carats. The gem was discovered in the 1920s in Litchenburg, South Africa.

It was 35 carats uncut. A diamond broker paid eight pounds per carat for it.
The Moussaieff Red Diamond is a diamond measuring 5.11 carats with a triangular brilliant cut, rated in color as Fancy Red by the Gemological Institute of America. It is the world's largest known red diamond.

The Moussaieff Red was discovered in the 1990s by a Brazilian farmer in the Abaetezinho river in 1990, in a region known as Alto Paranaiba. The rough stone weighed 13.9 carats.
The Rob Red Diamond is modest in size at 0.59 carats but it still holds a special place in the diamond world. The Rob Red is rated as the most intense red diamond ever discovered. The diamond is rated fancy purplish red by the GIA and is considered the most important red diamond in the world.
The De Young Red is 5.03 carats and graded as Fancy Brownish Red. It was found in South Africa in 1927. The stone was once mistakenly sold as a red garnet that was set in a hat pin.

Eventually the garnet was proven in fact to be a diamond. The diamond currently resides at the Smithsonian.
The Supreme Purple Star. There is very little known about this diamond. The uniquely coloured stone came to the world’s attention when it surfaced in London in 2002. When the owner took it to an appraiser in London, he was not aware of its rarity. The colour of the diamond changes as it is rotated. It goes from a deep purple to a vivid purplish red making it a diamond unlike any seen before.

It is unknown what has become of the diamond.
A heart-shape fancy red diamond ring by Moussaieff set a world auction record at Christie’s Hong Kong on November 25, 2014.

The 2.09 carat ring sold for $5,095,872, setting a new record of $2.44 million per carat.

Ancient Egyptian Mummy Wearing Jewels Found

Spanish archaeologists digging in Egypt have unearthed a female mummy still wearing her jewels. The mummy was discovered in the necropolis below the temple of Pharaoh Thutmosis III (1490-1436 B.C.), on the west bank of the Nile in Luxor. The find dates to the Middle Kingdom (2137-1781 B.C.)

For nearly four millennia, the “Lady of the Jewels,” eluded tomb raiders, her sarcophagus trapped under a collapsed roof.
The archaeologists were cleaning and restoring several tombs in the necropolis that had been already looted in antiquity when they realized that in one of the chambers of tomb XIV, part of the roof had already collapsed before robbers entered it.

“A large boulder, which had fallen down before the tomb was looted, had crushed and buried a previously untouched coffin with all its content,” Egyptologists Myriam Seco, director of the Thutmosis III Temple Project, said in a statement.
“These spectacular findings confirm that an elite necropolis is located under the mortuary temple of Thutmosis III. Wealthy and important individuals of the Middle Kingdom and their families were buried there,” Seco said.
