59.60 carats Largest Fancy Vivid Pink Diamond - The Steinmetz Pink.

Steinmetz Pink is the Largest Fancy Vivid Pink Diamond in the world. It weighs 59.60 carats and has been graded as Internally Flawless by GIA, which is an extremely rare and coveted clarity grade. The 100 carats rough, discovered in South Africa has been cut in a unique pattern, oval mixed cut with a step-cut crown and a brilliant cut pavilion.
The pink diamond is the world's most rare and valuable diamond. The cause of color in pink diamonds is thought to be plastic deformation, brought about by microscopic imperfections at the atomic level. It is estimated that for every million carats of rough diamonds found, only 1 carat is intense pink!

The Steinmetz Pink Diamond was first unveiled in Monaco in May, 2003. It took a team of eight people working approximately 20 months to cut the diamond in its present shape. Fifty models were worked on before the cutting even began. The one in itself gem was recently valued at 25 million dollars.
