“The oldest thing on earth is smaller than a piece of human hair. Researchers from the University of Wisconsin, Madison, have determined that blue zircon crystals found in a remote part of Australia are 4.4 billion years old, just 160 million younger than the formation of our solar system.” 

Old is Blue.
