Geology/Question about Kimberlite Rock


Hello-My son found a rock that he thinks may be a Kimberlite.  I have attached a photo and ask if you have an opinion whether it may be a Kimberlite or not.  Also, if it looks like it might be, where would we go to verify.  Finally, are Kimberlites worth anything monetarily?  Thanks.

The rock that is in the picture is probably not kimberlite since it is and extrusive igneous rock (air pockets) and kimberlites are generally intrusive. Kimberlite has no value itself but is an indicator of diamonds.  In essence, kimberlite is the rock in which diamonds occur but it is not the container that is of value it is the contained (diamond). You should be able to take the rock to any higher education geologic department to determine for sure.

I am an economic geologist. An economic geologist does mineral evaluations and appraisals of mineral or mining properties. I can tell you if your deposit has value - remember that a mineral deposit, no matter how good, only has value when mined. Any value assigned to a mineral deposit, in the ground, is only the speculative value that deposit.


I have been a economic geologist for most of my 35 year career. Although I have done work in perhaps 45 states and numerious countries much of my work has been in Appalachian coal, intermountain west gold and silver, and Arizona uranium.

Past President of the Virginia Section of the American Institute of Professional Geologists and a certified geologist in twelve states.

BS Degree from Eastern Kentucky University. Work on MS Degree @ Eastern Kentucky University, Colorad School of Mines & Marshall University Numerious short courses on the value of mineral deposits and how to value same. Also several short courses dealing with the different types of geologic processes; sedimentary, igneous, metamorphic along with the mineral associated with each.
