Blue Diamonds
Wednesday, March 5th, 2008Natural blue diamonds are so rare that most jewelers have never seen one, and will never own one. In recent years, methods of producing intensely colored diamonds, including fancy blue, have been developed. We believe that the process probably recreates the conditions which existed millions of years ago to produce natural fancy colored stones. The treatment can only work with a small minority of diamonds, and involves irradiating them causing the color change, usually followed by heat treatment to stabilize the color. The blue diamonds we currently have available are enhanced or treated. If this fact puts you off owning one, then please stop to consider that every diamond has been enhanced by faceting, and most colored gemstones are heat treated to enhance their color. We will add a page devoted to gemstone treatments when we have more time.
