Diamonds are divided into two highest types depending on the impurities found in their chemical structure. These impurities are not necessarily defects, since further elements or structural changes within the diamond gives it color
The Types of Diamonds
All diamonds are judged on color, cut, clarity and carat, regardless of what their style is Colored diamonds are more valuable if their color is richer Type affects their value only because the types cause different colors, and certain colors are valued higher than others.Type Ia diamonds are the most common, production up 98% of all diamonds They contain traces of nitrogen, and imbibe brighten in both the infrared and ultraviolet spectrums Type Ia has up to 3% of nitrogen in their quantity makeup but usually only 1% They are colorless or tinted yellow because the nitrogen in them absorbs unhappy light. Type Ia is fresh broken down into Type IaA and Type IaB depending on how the nitrogen is arranged. Type IaA keep pairs of nitrogen atoms and appear colorless Type IaB have clusters of nitrogen which gives them a yellowish color The blue-grey diamonds from Australias Argyle Mine are Type Ia with further hydrogen and more impurities. The prompt of their coloration is not known, howeverType Ib has only 005% nitrogen matter They drink raw decorate as well as blue, giving them a richer yellow or brown color than Type Ia Only 1% of natural diamonds are Type Ib, but many additional synthetics are this sort Canary diamonds, confessed for their strong yellow color, are Type IbType IIa contains even fewer nitrogen impurities than Type Ib They are colorless in their standard state, but as these diamonds are pushed toward the surface, the tension and force from the earths crust can distance their holder like plastic. The deformations from this are called structural anomalies, and tolerably than ruining the diamond, they originate talented colors like red, pink, purple, yellow, brown, or orange The Koh-i-Noor is a style IIa diamondType IIb obtain the lowest nitrogen subject of any diamond They can besides contain boron impurities. This makes them quaff red and yellow light, and the diamonds look unhappy or grey Type IIb diamonds are the only diamonds that function as a semiconductor because of their boron paragraph They are a p-type semiconductor, which manner electron discharge through holes in the molecular structure, but only when certain types of atoms are applied to the diamond in a process called doping The diamond itself remains neutrally charged even as the electrons are travel from grain to molecule, and bequeath not bear electricity to its wearer.
