I did say "Where a kimberlite pipe surfaces they are found the size of a small rounded pebble"
...I should have added, thats because they are either water worn or contact worn with sand or gravel.
I have never seen a raw 'straight out of the pipe diamond' Those in the Geological museum have most probably been scraped and lightly polished externally?
But I am sure that a 'raw diamonds' shape is in the form of two pyramids stuck base to base, since they form under heat and pressure (Not sure of that crystals name)
One interesting fact about diamond, it has a VERY strong affinity to Petroleum grease/jelly, something to do with electron surface attraction.
