Diamonds in lamproites?
I just came back from the Crater of Diamonds in Arkansas. I found and brought back some rocks that I'm pretty sure, based on research, that are lamproites. I was wondering, how common is it for diamonds to be in these rocks, how big are the diamonds found in them, how do you know if one of them has a diamond inside, can you see the diamonds on the surface, and most importantly, how do you get the diamond out of the rock? Or open it up to see if there is a diamond inside?

I dont think i can answer all your questions but ill give it a try. hardness is obviously the most distinguishing feature, see if the diamonds can scratch something really hard. for some reason im unsure of diamonds stick to grease, in fact many diamond operations run the rock over angled greased boards and pick out the diamonds. Not sure exactly how that works or what kind of grease they use but you could look it up. getting the diamond out of the rock? thats a tough one, you would want to grind it somehow with something soft that wouldnt break up the diamonds. thats how industry does it I believe.
