Color Diamonds
Diamonds form naturally in the earth under conditions of extreme temperature and pressure. Most diamonds are pure or nearly pure, causing them to be transparent and mostly colorless. Sometimes, though, other elements seep into the carbon atoms of the diamond, causing different colors to display. Gray and blue diamonds are caused by the presence of boron. Yellow and brown diamonds have been exposed to nitrogen. And diamonds that have been exposed to natural radiation turn green. Other natural colors include pink, purple, orange and even red.

Investment Grade
Fancy Color Diamonds are highly sought after because of their extreme rarity, captivating beauty, and unique color combinations. Naturally colored diamonds range from extremely rare and expensive stones to more obtainable and affordable ones. Unlike colorless stones, which contain shades graded from D – Z, Fancy Color Diamonds are found in 12 different primary colors, with more than 90 secondary hues, 9 intensity levels and over 230 color combinations. The Fancy Color Diamonds with the best track record of performance are called Investment Grade Diamonds.

Argyle Color

Argyle Color

The Argyle mine is one of the largest mines in the world, and is the main source of the rare natural fancy pink diamonds. It produces about 90 percent of the world’s supply of pink diamonds. The stones are so highly valued that between 40 and 60 of the best diamonds are put out to tender every year. The natural red diamond, one of the rarest among fancy color diamonds, is so rare that only a few stones are mined each year. Even these diamonds, produced by the Argyle mine are not pure red but rather graded as fancy-brownish-red, vivid-purplish-pink, Fancy purplish-red, and a few other variety of hues.
