Da Yooper's Rockhounds Guide to

Michigan Diamonds

Diamonds in Michigan, yes, but, where, what quality, size and quantity? So far about 20 locations have been found and explored. However no commercially significant discovery has been made. The most well known location is the Lake Ellen exploration North East of Crystal Falls, Michigan

The majority of the possible Diamond bearing strata ocurr in a line from Crystal Falls East to Hermansville./Powers area. It is my privlige to be aquainted with Shawn Carlson, a geologist involved in the Diamond Explorations of the U. P. in the recent past. Shawn has suggested that no significent commercial discoveries have been made to date. No diamonds have been found in quantity, or larger than 1mm in the explorations.

However, the Lake Ellen location does have Ruby-Red Pyrope Garnets, and Magnesium Ilmenite of gem quality. I have found 1 inch, and one half inch Garnets as well as many smaller ones. Some of them are of fantastic color. The Hermansville location yielded beautiful Peridot from the drill core. However, this location is under water and not available to the rockhound.
