About Natural Fancy Blue Diamonds
The color most often connected to royalty, wisdom, and prestige. Fancy blue diamonds are quite valuable and often considered to be extreme rarities, even among other fancy colors. Blue colored diamonds are often sought after by some of the most rich and famous.
Most fancy diamonds, including natural blue colored stones were originally found in India. However, South Africa has recently been one of the most dominating producers of fancy blue colored diamonds. They have taken the lead in the production of blue diamonds, specifically from the Pretoria mine. The Argyle mine in Australia is also famous for some of the magnificent blue and violet colors, often containing a grayish secondary hue.
Pure Fancy Deep and Fancy Vivid Blue
Blue colored diamonds are rarely found with a pure, straight blue color. They often contain overtones that are present due to the result of the Boron elements contained within. The most common secondary hues found with blue diamonds are either Gray-Blue or Green-Blue.
