Why are pink diamonds so rare and expensive, simply put diamonds are most common in color ranging from white, to brown and yellow. The more intense the natural color or in the case of white diamonds the lack of color, the more rare and expensive the stone. Certified natural Fancy Vivid pink diamonds are the most expensive diamonds on the market ranging in price from 30,000 to 100,000 per carat, 20 times the price of a white diamond. The majority of all pink diamonds mined come from one source in Australia, the Argyle Mine. Argyle Pink Diamonds are so expensive because of the very limited supply.
A pink diamond is formed of only carbon like a white diamond, through millions of years in the kimberlite pipes of volcanoes. Trapped chunks of carbon (the same carbon used to make pencils) are transformed by extreme heat and pressure into the glass like diamond. A pink diamond has been exposed to even more intense heat, pressure, and time transforming the diamond crystals into grains like wood. The grains are compressed so tightly that they will only allow pink light to penetrate and shine through the diamond.
Enhanced colored stones are at a minimum heat-treated (HPHT) this process makes an off white stone whiter, and a brown stone into a vast array of colors from pink to blue and green. A colored stone that is irradiated and heat-treated will become vivid and saturated with color. These processes are permanent and do make a fancy colored stone or a white more reasonable in price. The choice between a natural and a treated stone is a personal one, they are both beautiful diamonds and will provide the wearer with a life time of enjoyment.
