I listened pure diamonds are transparent, so the most coloured it has worse value.
But if, for example in Jewellery black diamonds start to be demanded, could a black diamond be (in the same conditions except the colour) be more expensive than a transparent diamond?

Hi Olga.
In short, no.
The majority of black diamonds are irradiated dreck and the natural ones are black because of numerous inclusions.
The only seriously valuable black diamond is the Orlov and that has more to do with the alleged provenance than the fact that it is black.

Natural untreated fancy colored diamonds, pink, red, blue, vibrant yellow command very high prices because of their rarity.

And, my favorite colored diamond site: Lagerman

They have the coolest poster of all time:

I've wanted this poster for years. I think it is time for me to order one.
