Here's a little item I found on another forum.
http://www.sciencenews.org/view/generic/id...onds_to_surface This thin slice of a kimberlite rock from northern Canada, seen through a microscope and in polarized light, shows colorful minerals caught up in magma that rose from deep within the Earth. Leonard |

Hi MR,
Looks like you have some form of Garnet in that one specimen however its very unlikely to be Pyrope garnets as they are only formed inside Kimberlite. The other rocks looks interesting, not something I have seen before. And yes haha don't bother looking for anything else if you are looking for kimberlite. There are a few in Colorado but the diamond bearing ones are all tied up and off limits to everyone. However if you are keen you can look in this area 39° 4'34.29"N 105°16'33.17"W in CO there is rumoured to be a diamond bearing pipe there in the area... You have samples of what to look for go get it! Very good luck, lots of water and food off the 51. Have fun DD |
