All diamonds are at least 990000000 million years old and formed under intense heat and pressure 100 miles below the earth's surface.Luckily you'll have the liberty to perform a similarly act with this intensely challenging puzzle at your leisure - maybe even in an air-conditioned room! But be warned: you might need just as much time! Well, to make things easier instead of forming carbon into diamond crystal, you'll only need to assemble the 12 wooden pieces into a diamond shape.
