Yellow diamonds are fancy diamonds. These natural, untreated, colored diamonds are rare. One in every 10,000 carats is a natural fancy colored diamond. Their rarity is only matched by their beauty. They are consistently the highest priced items at the highest profile Auction Houses (both Sotheby's and Christie's).
Natural Fancy Colored Diamonds can be found in almost every shade of color, from pale pink to dark black. Their ownership is a rare privilege and they are appreciated and sought out by collectors and specialist jewelers worldwide.
In it purest state, a diamond is composed of carbon atoms and is colorless. When certain atoms replace carbon atoms, they impart tints of color. Yellow diamonds are the result of nitrogen atoms being present when the diamond is formed. The presence of boron atoms results in blue diamonds. Diamonds that are pink to red and orange in color have imperfections at the atomic level which scientists call “color centers.” Green, blue-green, and a small number of blue diamonds are a special case. Their colors result from exposure to radiation over thousands to millions of years in the Earth. In all of these cases, portions of white light striking the diamond are absorbed. The remaining portions of light that are not absorbed are transmitted to the eye and result in the color we see.
Because of their rarity these diamonds are often expensive. Generous Gems is pleased to make these rare beauties affordable. How can we do this? We are using smaller carat size diamonds (from .01ct to .10ct) for most of the items available through our site.
This extraordinarily rare 101.29 carat stone is named after its former British owner, Major Alfred Ernest Allnatt. There are fewer than a dozen known diamonds that weigh over 100 carats and have a strong yellow color, and even fewer that attain a vivid grade. It is no surprise, therefore, that the Allnatt commanded the fourth highest auction record price for a single yellow diamond. Experts believe that the likely source of the Allnatt is the De Beers mine in South Africa.
