Some gem-quality diamonds are ranked as 'colourless'. This grade is a D grade diamond.
Natural diamonds in the white color scale are graded from D (colorless) to Z (light yellow). The white color range is known as G-H grade. The question of whether what you are looking at is real or not should be considered regarding the material rather than the color, as natural diamonds come in very many colors, usually white. Check if the diamond is man made, cubic zircon, Russian simulate or something similar. Clarity enhanced diamonds are also real, natural diamonds. Diamonds are valued by how closely they approach colorlessness - the less color, the higher the value. Most diamonds found in jewelry stores run from colorless to near-colorless with slight hints of yellow or brown. The only exceptions are the fancy color diamonds that lie outside of this range. Many of these color distinctions are so subtle that they are invisible to the untrained eye. But these slight color differences make a very big difference in diamond quality and price. PS - The diamonds described above are actually not white but colorless. There are truly white diamonds they are very rare. The best are opalescent and quite beautiful.

Diamonds are usually clear and they are hard. Zircon can also the colorless and is a hard mineral.
A 'colourless' diamond is one with minimal amounts of any other mineral except carbon. Trace amounts of some minerals, and some formation abnormalities cause diamonds to be coloured.
Yes. Argon is a colorless, odorless gas.
Which of the unknown colorless solutions is (are) acidic
It's the colorless diamonds, sometimes called white diamonds, which all other shades are judged against. Colorless diamonds and diamonds that are yellow or yellowish brown are generally cheaper.
No. Pink diamonds are little more but they are both more expensive then colorless diamonds.
Black diamonds are black.
Red, Blue, Yellow, Green or colorless
White diamonds are valued on there color. The nearer a white diamond is to colorless the rarer it becomes. This raises the diamonds value. Imperfections in white diamonds lead to discoloring and can greatly reduce the value.
A 'D' grade for a diamond refers to its colour. This grade is the highest jewelry grade of diamond, and it means that the stone lacks significant nitrogen, which gives a diamond a yellow colour.
If you are after a white diamond then the clearer it is the better, However blue or pink diamonds are also highly prized and VERY rare.
yellow diamonds are just very flawed white diamonds, they are extremely common compared to colorless (white) diamonds and are used for tool and other things because the jewelry world sees them as "ugly" or "useless" but like all things sometimes someone likes yellow diamonds and request for one but those are rare, isolated cases.

No, because they are rocks. Mineral rocks to be exact. Want more info? Keep reading... Diamonds are the hardest rock ever known Streak is colorless Level 10 on the Mohs scale Luster is Adamantine
Diamonds are usually clear and they are hard. Zircon can also the colorless and is a hard mineral.
Cubic Zirconia is a synthesized stone that has relatively low cost and is the leading competitor for diamonds. they are usually colorless but can be made of many colors.
