Most orange diamonds are found in one of two places: the Argyle mine in Australia or South Africa.
What gives these stones their unique hue is the presence of nitrogen - which is the same element responsible for the color in yellow diamonds. According to the Natural Colored Diamond Associa- tion, nitrogen atoms must be grouped in a hyper-specific way while the diamond is forming. When they are situated in this particular arrangement, they absorb blue and some yellow light, thus produ- cing an orange appearance.
