4. How Blue Diamonds are Made?
Similar to all other fancy colored diamonds, natural blue diamonds are made by nature. Though the process that diamonds go through including cutting and polishing can have an effect on a diamond’s color, blue diamonds are actually found with their beautiful blue color tone. An impurity called boron, along with nitrogen, is the cause for the color.
5. How is the Blue Diamonds Formed?
The formation of all diamonds is something that happens over millions if not billions of years. Under conditions of immense pressure and heat, Carbon elements form together into rough diamond rocks. The addition of the blue color is simply other elements that compound themselves together with the Carbon. Studies have shown high levels of Boron are the actual cause to the bluish tint, but other elements can have different affects as well depending on the levels that the stone contains.
6. Where do Blue Diamonds Come From?
Blue diamonds are only found in a few mines around the world. These mines include the Cullinan mine near Pretoria, South Africa, and the Argyle mine in Australia. Once, blue diamonds were mined in India’s famous Golconda mine as well.
7. Are Blue Diamonds More Expensive than Other Colors?
Blue diamonds are more valuable than most colored diamonds, but just like all other diamonds, their prices are determined based on the diamond’s color, color intensity, size, and clarity with an emphasis on the intensity of the color. Blue diamonds are highly sought after by diamond collectors and enthusiasts worldwide. A very small blue diamond can cost a few thousand dollars, and a large one such as the Wittelsbach-Graff diamond can cost millions. Because they are so rare, blue diamonds tend to get snatched up very quickly and fetch very steep prices. Nevertheless, no diamond collection is complete without a blue diamond.
