Type II diamonds absorb in a different region of the infrared, and transmit in the ultraviolet below 225 nm (2.25 ×10 −7 m), unlike Type I diamonds. Type II diamonds have no measurable nitrogen impurities. They also have a characteristic fluorescence and visible absorption spectrum (see Optical properties of diamond). Type I diamonds absorb in both the infrared and ultraviolet region, from 320 nm (3.2 ×10 −7 m). Synthetic diamond containing nitrogen is Type Ib. If the nitrogen atoms are dispersed throughout the crystal in isolated sites (not paired or grouped), they give the stone an intense yellow or occasionally brown tint (Type Ib) the rare canary diamonds belong to this type, which represents only 10% of known natural diamonds. About 98% of gem diamonds are type Ia, and most of these are a mixture of IaA and IaB material: these diamonds belong to the Cape series, named after the diamond-rich region formerly known as Cape Province in South Africa, whose deposits are largely Type Ia. If the nitrogen atoms are in large even-numbered aggregates they impart a yellow to brown tint (Type IaB). If the nitrogen atoms are in pairs they do not affect the diamond's color these are Type IaA. Type I diamonds have nitrogen atoms as the main impurity, commonly at a concentration of 0.1%. Diamonds are scientifically classed into two main types and several subtypes, according to the nature of impurities present and how these impurities affect light absorption. Colored diamonds contain interstitial impurities or structural defects that cause the coloration pure diamonds are perfectly transparent and colorless.

The 296 gems of the Aurora Pyramid of Hope as exhibited in the Natural History Museum in London under natural light.ĭiamonds occur in a variety of colors-steel gray, white, blue, yellow, orange, red, green, pink to purple, brown, and black. The Aurora Pyramid of Hope displays a spectacular array of naturally colored diamonds, including red diamonds. Of all colored diamonds, red diamonds are the rarest. For example, most white diamonds are discounted in price when more yellow hue is detectable, while intense pink diamonds or blue diamonds (such as the Hope Diamond) can be dramatically more valuable. Depending on the hue and intensity of a diamond's coloration, a diamond's color can either detract from or enhance its value. The color of a diamond may be affected by chemical impurities and/or structural defects in the crystal lattice. However, in reality almost no gem-sized natural diamonds are absolutely perfect.
