Natural Blue Diamonds
Natural fancy blue diamonds are completely natural and are usually classified as either gray-blue or green-blue. The color in gray-blue, grayish blue, blackish blue or black-blue colored diamonds is caused by the presence of minor amounts of boron in their structure. Green-blue or greenish blue (teal) colored diamonds usually contain nitrogen impurities in aggregate form.
The most famous of all natural colored blue diamonds is the 45.52 carat 'Hope Diamond'. The Hope Diamond was originally 112.25 carats when it was purchased in India and sold to the French King Louis XIV. $569,000 is the most paid per carat for a blue diamond (for a 4.37 carat diamond sold in 1995 at Christie's for $2,486,000).
Natural fancy blue diamonds range from the pale to brilliant blue diamonds and intense blue diamonds.
Natural fancy blue diamonds come in all cuts, including princess, emerald, asscher, oval marquise, pear, radiant, heart and cushion, though round natural fancy blue diamonds are the most common.

Natural Pink Diamonds
Natural fancy pink diamonds are completely natural and caused by a process called 'plastic deformation' when pink graining is caused by a natural deformation of the diamond crystal while it is in a semi-solid state. Most fancy natural pink diamonds come from the Argyle mine in northwestern Australia. "... Diamonds with a pink body color have long been considered one of the rarest varieties of diamond." (source: S.C. Hofer, Pink Diamonds from Australia, 1985).
The seven natural color grades for natural fancy colored diamonds are, in ascending order, faint, very light, light, fancy, fancy intense, fancy vivid and fancy deep. Fancy vivid and fancy deep the most desired hues.
Red, purple and orange are the secondary hues found in natural fancy pink diamonds.
Today, the pink diamond is playing the role of Cupid among the colored diamonds. Ben Affleck purchased a 6.1 carat pink diamond ring for his engagement to Jennifer Lopez and David Beckham gave his wife, former Spice Girl Victoria 'Posh' Adams a $1.8 million pink diamond apology ring following his public indiscretion.
