The jewelry grade (white) diamond that is most valuable is identified as a D-colour stone. In fancy coloured stones, both blue and pink stones are valuable, although red might be the most rare, and therefore the most valuable. See the link, below.
The most valuable stone is typically considered to be the diamond, followed by sapphire, ruby, emerald, and then semi-precious stones such as amethyst, citrine, and peridot. The value of a stone is determined by factors such as rarity, color, size, and clarity.

Not necessarily.A diamond is valued according to its cut -- round in this case, carat weight, colour and clarity.Larger stones, of course, will be more valuable than smaller stones.Larger more clear stones are usually cut in an emerald cut.Fancy coloured stones are cut to highlight not only the colour but whatever other valuable attribute exists in the stone.
