Hey Everyone, thought this was an interesting tid bit worth posting........Colorado produced North Americas largest faceted diamond. Here is a bit of info from the Kelsey Lake mine.........
QUOTE
The Kelsey Lake mine, located almost on the Colorado-Wyoming line, includes some eight kimberlite pipes, the two largest of which have a combined area of about 20 acres (Hausel 1998). The mine was first opened by Redaurum, a Canadian company; ownership changed to McKenzie Bay International, and it is currently owned jointly by Roberts Construction and BJ&J Jewelers, two North Dakota companies. It was operated from 1996 to 1998 and produced North America's largest-known cut diamond--a pale yellow 16.86-carat faceted stone that was cut from a well-formed 28.18-carat crystal found in 1997. Another, a 28.3-carat yellow diamond mined in 1996, was cut into a 5.39-carat pear-shaped stone.


I'm still looking for some pics of the faceted stones.
