For many years now, the trade in fancy color diamonds has been an exclusive affair of those who are extremely wealthy. These fancy colored stones are so rare and expensive that they are sold only in the finest and most exclusive jewelry stores. Most are owned by serious collectors with immense wealth. The rarest and most expensive of all diamonds are the pink diamonds. These stones are very rare; they are known to come from only one mine situated in Western Australia called Argyle mine. The fact that these stones are highly fancied yet so scarce makes them very expensive indeed.

The Argyle mine is the ultimate source of pink diamonds for the whole world. It produces more than 95% of all the pink diamonds in the world. Ever since its discovery more than twenty years ago, the popularity of the Argyle diamond has grown to legendary proportions. It displays strikingly intense shades of color. Before the discovery of the Argyle mine, there were a few pink diamonds from India, Brazil and Africa but these were lighter in color and look even paler when put next to the intensely pink Argyle diamonds. This has contributed further to the value of the Argyle stones.

Pink diamonds come in a variety of color shades. These range from delicate pastel rose to strong raspberry and whole-colored purple reds. The intensity of the color ultimately determines the price per carat. Only the most vibrant pink diamonds are polished for the high end market. The stones are cut and polished into round brilliant, marquise, oval and pear, to enhance their natural beauty. Natural pink diamonds are so rare that a treatment process has been developed to alter the color of some diamonds. This has further pushed the value of natural pink diamonds in the market.

One needs to do some serious thinking if he or she is planning to buy a pink diamond ring. Argyle privately sells pink diamonds for up to $1 million a carat. Pink diamonds are much more expensive than ordinary near-colorless ones or white ones of the same quality and size. Natural pink diamonds are more expensive than enhanced color diamonds. Deep, intense colors also fetch more value than pale ones. Due to the extreme rarity and very expensive nature of pink diamonds, most are sold at invitation-only bids. There a few companies selling pink diamonds readily in their stores apart from Argyle.
