Seriy, No offense.
You no sign of emotion in the topic, though I think only to be disappointed.
Really expensive diamonds, those that are clean, - "flawless" ie without inclusions and absolutely colorless "River"
Yellow and black are the cheapest.
Diamonds are still classroom theme for divorce.
Believe it or not.
Optavaya price in Europe of the diamond (standard grinding, doing so and so machine), the size of a 1 carat in high purity and whiteness, is 80 - 100 euros.
However, each step toward improving the quality of purity and whiteness, increases the price of stone in geometric progression .
