first carbonado black diamond discovered in wisconsin

Finding this black carbonado dimaond in a kimberlite pipe changes the science!

It is currently hypothesized that the origin of black carbonado diamonds is either meteoric or kimberlitic. The debate is primarily due to the fact that no one has ever reported finding a single carbonado diamond originating from a kimberlite pipe, until now! This discovery proves that at least some, or maybe all, carbonado diamonds found on earth actually form in the earth.

The significance of this discovery is that two carbonado diamonds have been discovered inside of a diamond bearing kimberlite in Wisconsin. Adding to the excitement of this discovery, this is likely the first one ever found in North America.
