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.
Diamond can be colorless; but graphite, coal, carbon black are black.
The hardest diamonds are colorless. In the diamond industry, the highest quality diamonds are those that are graded as "D" color, which is completely colorless. These diamonds are highly valued for their rarity and brilliance.
One example of a colorless hard mineral is diamond, which is composed of carbon atoms arranged in a crystal lattice structure. Diamond is the hardest naturally occurring mineral and is known for its exceptional brilliance and clarity.
A diamond is valued by its cut, clarity, carat weight and colour. Depending on your taste, you can buy a diamond in most any colour; and pay most any price for the stone you want. "Good" is relative. The highest colour grade for a 'colourless' diamond is D. Otherwise, in a coloured stone, the highest colour grade is Vivid Fancy [colour].
A pure diamond is a diamond that is composed solely of carbon atoms arranged in a crystalline structure. It is colorless and is known for its exceptional hardness and brilliance. Pure diamonds are valued for their rarity and beauty.
The streak for a diamond is colorless.

Diamond and quartz are colorless minerals that also have a colorless streak. This means that when these minerals are scratched against a white ceramic plate, they leave behind a streak that is also colorless.
I'm pretty sure you can't do that. I know that if you expose the diamond to extreme heat it can enhance the natural color, but not to such an extreme degree as to remove the brown from a diamond and convert it to a colorless diamond. Usually brown diamonds are formed when minerals or elements get trapped within the diamond's chemical structure creating a tint. This is impossible to change. Diamond clarity, however, can be enhanced by using a laser.
Colorless. Any color it appears to have is due to the refraction of light.
When a diamond is crushed into dust, it appears colorless. This is because diamonds are typically transparent and colorless in their natural state. The crushed diamond dust may appear sparkly due to its structure, but it does not display any specific color.
