Diamond formation and sampling

[Kidlapik]

I am a bit naïve when it comes to the formation of diamonds but I had a thought. As larger diamonds are heavier are they more likely found deeper? Or does their weight have little to do with where they are found in a kimberlite as the forming simply pushes them up regardless of their weight as even a larger diamonds "weight" is not really that substantial. Anybody know?

My understanding is that it is a rather violent event. Anything in the way gets pushed up. It's an interesting question. Hopefully someone with knowledge will answer.

I've never read or heard of the concept of heavier diamonds being deeper in a kimberlite. The density and viscosity of the magma is very high and the weight of a diamond very low. 1 carat = 0.2 grams. Also consider that Xenoliths (fragments of country rock -sometimes huge) can stick out of the ground *within* a kimberlite. Then there is degassing. Like when you open a soda pop. That would stir

Diamond eruptions blast to the surface  at around 150km per hour.This is the lowest threshold for gem diamonds not to burn.Anything under that the diamond quality suffers as it is exposed to the heat too long and then gem stones turn to boart brown/gray.As for Chidliac the event was a cold eruption as a result the quality of these diamonds are high.

Learned something new about Gold/Silver type deposits. If it is a steam furnace pipe that brings up the material, it will deposit the heavier Pb/Uranium first and then move up to Gold/Silver at a higher elevation. So you can end up having Gold/Silver veins 100 to 400 metres below surface and then Pb and related heavier elements can be much deeper. So, when they say the deposit is open to depth.
