Yellow is one of the most familiar names known aside from white "colorless" diamonds. Canary is a term commonly used to describe fancy yellow diamonds. Some yellows with higher intensity of colour such as intense deep or Vivid are as rare as smaller pinks and blues and command unusually high prices.

Pink diamonds are extremely rare and highly desired. Pink diamonds of higher intensity are the most rare and command extraordinary high prices. Most pink diamonds mined are faint to light colored (pastel colored). The most desirable fancy, intense, deep and vivid colours come primarily from the Argyle diamond mine in Australia

Natural blue color is one of the rarest of fancy color diamonds. These diamonds are amongst the most sought after by collectors. Color can range from faint to a very deep blue, an exceptional blue diamond can command even higher prices than a comparable pink diamond depending on size and colour saturation.

Red is by far the rarest of all colored diamonds. There have been less than 500 red diamonds to ever be graded and classified as red by the Gemological Institute of America.There have been half carat red diamonds that have sold for over a half million dollars at auction over the past decade, and the prices are climbing aggressively.

Green diamonds with no other secondary hues or modifiers are some of the rarest, and depending on intensity and purity of color, can command astronomical prices. Most green diamonds have either grey, brown or yellow modifiers.

Purple diamonds with no secondary hues are very rare. Most of these diamonds are less than one carat in size and are very seldom found in dark to vivid lilac colors. Most purple diamonds have a secondary modifying colour and exhibit needle-like color zones.

Orange diamonds are not as rare as the red or green daimonds. Most orange colored diamonds have strong yellow or brown modifiers. Pastel colored orange diamonds are of similar value as pastel pinks and some blues. A vivid orange can exhibit massive colour saturation.

Diamonds with grey as the primary dominant color are also unique. These diamonds are comparitively reasonably priced (in the high four to low five figures per carat).

Black diamonds are not transparent, and do not show fire (flashes of color) as other diamonds, but can be extremely expensive where they are in the dark to vivid color ranges. Black diamonds may give off secondary color hues of grey or white.

These are the most widely available and surprisingly affordable colored diamonds. They provide a beautiful low cost alternative to pink, blue, grey, green or yellow diamonds. Common names used to describe brown color are: champagne, chocolate, coffee, golden, honey, bronze, cognac, etc.
