Post wasn't deleted, not sure what happen, may be your youtube links as they did not work on either post, I edited start of both links and links now working.
Original links were "http://https://" I removed http:// in both links and they worked.
Was there supposed to be a commentary on those videos to explain what you believe we're looking at? I only get 'white noise' with some crackles and chinking sounds!
What causes you to believe these rocks are kimberlites or impact diamonds? Where are they from? You also posted in the "What's it Worth?" section, so it's pretty difficult to respond to that without more information... but Kimberlites and Impact Diamonds (which are two completely different things with wildly different origins) are not what I'm seeing.
