The largest GIA certified black diamond available in a quick Internet search is a Fancy black, cushion cut, 7.21 carat diamond with a retail price of US$18,125. You may be able to shop longer and find a larger diamond, and the cost will be comperable to its individual characteristics.
'Blue' is not a definitive colour description for a coloured diamond: varieties include "Faint, Very Light, Light, Fancy Light, Fancy, Fancy Dark, Fancy Intense, Fancy Deep, Fancy Vivid."

Generally, however, you will pay less for a colourless diamond rated M-Z in colour than you will pay for a similar diamond rated as 'faint yellow'.
