Diamonds have become the choice for investors who are into portable, tangible wealth. Auction after auction, record-breaking sales of shiny, hard assets are heating up.
The next supersized rock expected to set a new world record is not your average rock, it's a rare orange diamond called "The Orange."
Pure orange diamonds, also named "fire diamonds" are exceptionally rare. "The Orange" is a mega-diamond at almost 15 carats, making it the biggest of all fancy vivid orange diamonds to ever grace an auction block.

"This will become already a new world record per carat and for any orange diamond.
