I bet you didnt know this. I was reading a thread on diamond prospecting on the Colorado forums and found that impact craters like the one above are great for finding diamonds. See this quote:
Please consider my advice here...if you are prospecting an area near a known impact crater, I'd suggest that you also look for diamonds that may be associated with the crater. If the initial impact didn't bring diamonds to the surface, the resulting fractures in the granite may have allowed for later intrusive events to find a way up to the surface. In fact, many kimberlite pipes have shown multiple emplacements within the same diatreme. This makes sampling even more important since some parts of the pipe are too lean yet other intrusions have plenty of diamonds
