Diamonds are divided into two main types depending on the impurities found in their chemical structure. These impurities are not necessarily defects, since additional 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 species is Colored diamonds are fresh valuable if their color is richer Type affects their value only because the types engender different colors, and certain colors are valued higher than others.Type Ia diamonds are the most common, making up 98% of all diamonds They contain traces of nitrogen, and absorb brighten in both the infrared and ultraviolet spectrums. Type Ia has up to 3% of nitrogen in their total makeup but usually only 1% They are colorless or tinted yellow because the nitrogen in them absorbs woebegone light. Type Ia is additional 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 retain clusters of nitrogen which gives them a wan color The blue-grey diamonds from Australias Argyle Mine are Type Ia with supplementary hydrogen and additional impurities. The cause of their coloration is not known, howeverType Ib has only 005% nitrogen text They absorb fresh illuminate as well as blue, giving them a richer yellow or brown color than Type Ia Only 1% of common diamonds are Type Ib, but many other synthetics are this sort Canary diamonds, avowed for their strong yellow color, are Type Ib.Type IIa contains even fewer nitrogen impurities than Type Ib They are colorless in their general state, but as these diamonds are pushed toward the surface, the tension and force from the earths crust can grasp their frame like plastic. The deformations from this are called structural anomalies, and rather than ruining the diamond, they originate brilliant colors like red, pink, purple, yellow, brown, or orange The Koh-i-Noor is a kimd IIa diamondType IIb own the lowest nitrogen topic of any diamond They can further contain boron impurities. This makes them swallow red and yellow light, and the diamonds look blue or grey Type IIb diamonds are the only diamonds that function as a semiconductor because of their boron matter They are a p-type semiconductor, which routine electron disburden 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 movement from speck to molecule, and leave not transact electricity to its wearer.
