You can also find plenty of fancy colored diamonds in different shapes, styles, and designs. Fancy color diamonds are one of the rarest gemstones that naturally occur on the crust of the Earth. However, the rarity of colored gemstones has considerably increased the price of colored diamond rings. So, if you are on a tight budget, it is best to look for other viable alternatives.   The distinctive colors of a colored diamond engagement ring often create confusion among customers and they doubt whether these rings are real or not. Almost all of the colored diamond rings that naturally occur on the crust of the Earth are real. However, some jewelers often sell fake and real diamond rings alongside and both these types of rings look exactly similar to one another. So, if you are unable to decide which one of the diamond rings are real, then it is best to thoroughly examine the GIA grading certification documents of the rings.
