Pink diamonds are fancy colored diamonds that are very rarely found in nature. The color grading of pink diamonds ranges from faint, to very light, light, fancy light, fancy, fancy intense, fancy deep, and fancy vivid. Faint pink diamonds are the least expensive, while a fancy vivid pink diamond would be the most expensive. When you purchase a pink diamond wedding ring, make sure to get a GIA certificate that provides information regarding the quality and value of the pink diamond ring you purchased. This certificate is so important that without it, you may not get anywhere close to its original value when you resell it later on. A good option to buy a pink diamond ring is to choose a synthetic pink diamond,  instead of a natural one. This is because natural diamonds are very expensive, while synthetic ones are much more affordable. In addition, synthetic pink diamonds have the same physical, chemical, and optical properties as those of a natural pink diamond.
