Swarovski, recently unveiled the newly refurbished crystal star that will crown the 2009 Rockefeller Center Christmas Tree.

The star is high-tech: it has enhancements such as a new cutting-edge computerized lighting system and energy-efficient LED bulbs.

This is the first year that the Swarovski star, which debuted at the top of the Rockefeller Center Christmas tree in 2004, will feature dynamic light movement.

Astronomers discovered the largest diamond of all times in space. The weight of the precious stone reportedly makes up ten billion trillion trillion carats (or five million trillion trillion pounds).

The space diamond is virtually an enormous chunk of crystallized carbon, 4,000 kilometers in diameter.

The stone is located at a distance of 50 light years from Earth, in the Constellation Centaurus.
