Your question depends on the types of impurities you're measuring. Impurities develop both when the diamond is formed, and after the diamond is formed.
For example, if you are measuring visible impurities -- other minerals included within the clear gemstone -- you can measure them with a 10X loupe, and measure them visually.
You can read more about both types here: http://en.wikipedia.org/wiki/Diamond_flaws
Some 'impurities' are known: nitrogen causes yellow, gold and green; boron causes blue, other diamond colours are not so obvious. For example, pink diamonds are probably caused by a distortion in the diamond's lattice formation: the cause remains somewhat of a mystery. You can read more from two sources , below.
From Wikipedia: "The color of a diamond may be affected by chemical impurities and/or structural defects in the crystal lattice." You can read more about what impurities and defects cause which colours, below.
The major difference between yellow diamonds (also known as fancy yellow diamonds) and clear diamonds is their color. Yellow diamonds get their color from nitrogen impurities in the crystal structure, while clear diamonds, also known as colorless diamonds, have no noticeable color impurities. Yellow diamonds are considered unique and rare, while clear diamonds are more traditional and popular for engagement rings.
Brown diamonds are the most common colour of gem-quality diamonds found.According to its Wikipedia page:"Several causes have been identified, including irradiation treatment, nickel impurities and lattice defects associated with plastic deformation; the latter are considered as the predominant cause, especially in pure diamonds."
If you consider other minerals, such as nitrogen -- yellow, or boron -- blue, impurities, these minerals give a diamond the respective colour. As well, there can be visible flaws in a diamond, which are inclusions of other minerals within the diamond crystal that appear as dots or streaks.
Diamonds are formed from carbon. Some brown diamonds may contain trace amounts of nickel -- otherwise diamonds do not contain metals.

Impurities in diamonds, in this case nitrogen, gives the diamond a yellow tint. Champagne colour may be a brand name, in the same way that Chocolate Diamonds are a brand name for a specific colour and saturation of colour, all caused by nitrogen impurities in the gem.

The Hope Diamond is a Type IIb diamond, classified as such based on it's "...very low levels of nitrogen impurities comparable to Type IIa diamonds, Type IIb diamonds contain significant boron impurities. Type IIb diamonds make up about 0.1% of all natural diamonds," according to Wikipedia.

Diamond 'connoisseurs' prefer Type IIa diamonds, which are found in India and in South Africa. Type IIa diamonds are the purest form of diamond, containing zero impurities. From Wikipedia: "Type IIa diamonds make up 1-2% of all natural diamonds (1.8% of gem diamonds). These diamonds are almost or entirely devoid of impurities, and consequently are usually colourless and have the highest thermal conductivity."
No, diamond is a form of carbon. Other minerals contained in the stone can be considered impurities.
Natural diamonds are not blue in color. Blue diamonds are formed when the presence of boron impurities during their formation process causes them to absorb certain wavelengths of light, resulting in a blue hue.
No, chocolate diamonds are a marketing term used by Le Vian to describe brown diamonds. They are still real diamonds but have a distinct brown color due to the presence of nitrogen impurities. Regular diamonds can come in a variety of colors but are most commonly white or colorless.
