- Red Diamonds Red diamonds are the rarest and most highly valued of all fancy color diamonds. A red diamond is so rare that some jewelers have never seen a red diamond with their own eyes. Fewer than 20 diamonds have been certified as Fancy Red by the GIA. Many red and pink diamonds come from the Argyle mine in Australia and with the mine scheduled to close in 2020 the value of this exotic and vibrant diamond is only expected to increase. The most expensive by far, red diamonds have commanded over a million dollars per carat.

- Green Diamonds Natural green diamonds are characteristically light in tone and low in saturation. Their color often appears muted, with either a grayish, brownish or yellowish cast. Green diamonds with no other secondary hues or modifiers are some of the rarest. Green diamonds get their color when radiation displaces carbon atoms from their normal positions in the crystal structure. This can happen naturally when diamond deposits lie near radioactive rocks or artificially as a result of irradiation treatment. Due to their rarity and the very real possibility of treatment, green diamonds are always examined very carefully in gemological laboratories. Depending on intensity and purity of color, green diamonds can command astronomical prices.
