The emerald cut refers to the gems that square or rectangular in shape and featuring step-cut facets. The emerald cut diamonds can come in the market in variations of the traditional shapes. Generally, they are considered as affordable compared to solitaire diamonds, which refers to those featuring round-cut single stones mounted in the center.   The affordability, which transpires to the cost of emerald diamond engagement rings, is because round brilliant diamonds are cut into those shapes using a larger rough diamond when compared to square shapes. In other words, only less rough diamond is going to be wasted if the gemstone is cut into fancy shapes. This allows or produces a diamond with a bigger carat weight in the cutting process. Emerald diamond ring settings also play a great part in its pricing. Usually, a four prong or a six prong setting is used in diamond rings that feature an emerald cut stone, whereas a simple halo setting is preferred for round cut diamonds.
