Know that natural
l fancy color diamonds are very rare in nature and even rarer to the white diamonds. If you are looking for the rarest and most expensive colored diamond then settle for vivid red. But they are not practical to buy. Blue, pink, yellow and a range of complex colored diamonds such as green, orange, and a mix of many colors can also be your perfect choice. If you are looking for much less expensive fancy color diamond, then opt for lab created stones with the same properties and appearance of the natural color diamonds for engagement rings.
