Colored Diamonds -A Good Trend
- by Leslie Ackel
Recently, colored diamonds or “fancy diamonds” have become the fashion for those who can afford them. Many jewelers in Louisiana have experienced an increased demand for colored diamonds over the more traditional pure white diamond.
Choices of colored diamonds extend the length of the color spectrum. Blue, pink, yellow, green, orange, champagne, violet, gray, black and shades in between are mined for their exceptional uniqueness.

In order of rarity of the fancy diamonds, the red diamond is the rarest and often considered “priceless.” It is followed by the pink, blue, orange, green yellow and brown. Black diamonds are not truly black; scads of dark inclusions give them their dark appearance.
Following the reds, pink diamonds are among the rarest and most valued diamonds. Mined almost exclusively at the Argyle Diamond mine in Australia since only 1983, rare Pink Vivid diamonds attract 20 times the price of an equivalent white diamond. In 1985, the Argyle pink diamonds were sold individually only at high profile "tender" auctions.
Defects or impurities are the cause of diamonds developing their coveted coloration. The introduction of nitrogen creates the yellow and brown diamonds. Boron causes diamonds to become blue. Radiation exposure creates green, purple, pink, orange and red diamonds. According to diamond specialists, diamonds with these defects are beginning to hold their value longer than the traditional colorless diamond.

In 1878 Charles Lewis Tiffany purchased a rough 287.42 carat deep yellow diamond found in the Kimberely mines of South Africa. The following year he sent the diamond to Paris where it was cut to a 128.54 carat, 90 faceted cushion cut design diamond. Named the Tiffany Yellow Diamond, it remains one of the world’s largest and fanciest yellow diamonds. In 1983, the diamond’s estimated worth was $12 million.

Alternatives do exist
Since naturally colored diamonds may be cost prohibitive to most, gemologist have developed ways to create them less expensively -- They grow synthetic diamonds, which are real diamonds, from carbon inside laboratories instead of hundreds of miles underground. They start by taking an undesirable pale brown or yellow diamond, and add just the right amount of impurities and radiation to the diamonds. The results are vibrant colored stones or about any shade in between. The synthetics large enough to be produced into jewelry started being produced in 2004. According to experts, it is almost impossible to tell the difference between the two and certified gemologists must use scientific testing equipment in order to declare the difference.
The approximate cost of colored diamonds by carat weight are, Red - $300,000 ct; Green - $250,000/ct; Purple - $200,000/ct; Blue - $150,000/ct; Orange - $40,000/ct; Pink - $80,000/ct; Yellow - $12,000/ct; Gray - $6,000/ct and Brown - $4,000/ct.
