Y E L L O W Yellow diamonds are found in most diamond mines around the world. The biggest sources are South Africa, Australia, Canada and Russia. Yellow diamonds are caused when an atom of nitrogen replaces a carbon atom in the diamond’s crystal structure during its development in the earth, modify- ing light and absorbing the blue part of the visible spectrum. Thus, the greater the amount of nitrogen in the right patterns the stronger the saturation of color. de Boulle has a history of crafting yellow diamond masterpieces. Take for example our High Jewelry Collection 35th Anniversary Ring featuring a more-than-18-carat natural fancy yellow diamond framed in delicate pavé. WHAT THEY MEAN Joy and happiness. B L U E Blue diamonds are caused when an atom of boron replaces an atom of carbon in the diamond’s crystal structure during its growth in the earth. Depending on the amount of boron and its position in the crystal lattice, a blue diamond can appear as pale blues, like the sky, or deep blues, like the ocean. Most blue diamonds come from the Cullinan mine in South Africa. WHAT THEY MEAN Purity. G R E E N Diamonds which are green owe their appearance to naturally occurring radiation, which altered their atomic structure eons ago deep within the earth. The strength of the natural radia- tion and the duration of exposure determine the level of sat- uration. Exceedingly rare, green diamonds are found in var- ious mines in Africa, Brazil, Guyana and Venezuela. WHAT THEY MEAN Nature, abundance and prosperity.
