Why are polar diamonds considered the best quality in the world?

Question

What is it that makes the Canadian diamonds the best quality in the world? I was told it has to do with gravity in the poles and the weight of glaciers.

Can anyone help me?

Answer 1

It is the special conditions in which these diamonds grew that gave them supreme qualities when compared with other diamonds. And there is of course the fact that they are certainly conflict-free diamonds which means a lot to people that buy diamonds. In the upcoming years Canada, together with Russia will become diamond force No.1

Answer 2

Canadian diamonds are no different to any other diamonds. Each diamond mine produces a range of stones from material used for crushing into powder, industrial tool tipping material right up to gem quality stones. The Canadian mines produce a good proportion of gem stones to industrial material. The quality of a diamond is graded on its Colour, Clarity, Cut and carat weight and there is no way one can distinguish a D colour Flawless diamond (the absolute top grade for white stones) from any other D Flawless no matter which mine it came from, be it Africa or Canada. The source has no bearing whatsoever on the quality of the finished stone. This sounds like another bit of cleaver publicity to sell their goods.

Answer 3

The Canadian diamonds apparently started out as carbon-rich fluids locked up in rocks on the Earth’s surface. So how did that carbon get so far below the Earth’s surface that it was converted into diamonds? As it happens, the continents are made up of massive plates of relatively light rock that floats on top of the mantle, a semi-liquid layer of denser material dozens of miles down. These so-called tectonic plates butt up against each other, causing earthquakes and volcanoes, and eventually one will ride down under its neighbour, to be recycled in the mantle. As a result, surface material can easily end up over a hundred miles below the surface. During eons of geological time, the carbon-bearing rocks are dried out and subjected to such crushing pressures that their carbon rearranges itself into diamond crystals of various sizes. Eventually, some diamonds are included in magma that’s spat back out onto the Earth’s surface, where they’re collected by humans and fashioned into diamond rings for discerning consumers like you. The oldest such diamonds are found in cratons, ancient segments of continental rocks that are rooted deep in the mantle, and around which younger continental rocks grow.

I don't really know. I guess cause it's rare? sorry. I don't know!! :(
