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
Primarily Carbon with a few impurities
Diamonds can come colors based on the impurities they contain. A white diamond is generally pure while impure diamonds can be nearly any color in the rainbow.
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.
Pure diamonds are made solely of elemental carbon. Any colored diamonds have trace impurities consisting of various other elements. However, a pure diamond is simply carbon atoms bonded in a complex structure.
Yes, pure diamonds are made up of just carbon. Unless, they have impurities.

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."
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.
Diamonds can come colors based on the impurities they contain. A white diamond is generally pure while impure diamonds can be nearly any color in the rainbow.
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.
No, diamond is a form of carbon. Other minerals contained in the stone can be considered impurities.
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.
There are over 300 shades of colour that natural diamonds come in including pink, black, red and yellow. This is because of mineral impurities and lattice defects in the diamond.
yes. In the modern processes of making man-made diamonds, it has been found that impurities in the output are reduced when (tiny) diamonds are used as the feedstock rather than graphite as had been used before. see diamonds in wikipedia.org
Gemstones like diamonds are weighed in carats. A carat is 200 milligrams.
Carat is the unit of measurement used to measure diamonds, other gemstones and pearls.
