First, we need to understand the meaning of a diamond shape which is the physical form or appearance of a stone. Most common shapes are round, cushion, princess, asscher, emerald, radiant, heart, pear, oval and marquise.
Diamond shape is different from the diamond cut as the latter is the ability of a diamond to reflect light. The cut pertains to the facets and angles, its number, symmetry, proportions, that all affect how the light reflects out of the stone. Diamond cut grading ranges from Excellent to Poor showing as much light as possible to least light losing from the sides or bottom of the diamond. An excellent cut diamond will reflect so much light at the top face or table of the stone bringing out brilliant and fiery effect.

Why Round Diamonds Are More Expensive Than Other Shapes?
The price of a diamond is greatly affected by the shape. Round diamonds have been the most widely known shape over the years where 75 percent of it are sold across the globe. Round cut diamond's popularity has a direct connection with its optimal brilliance over other shapes where most diamonds in round cut category are considered brilliant cut thus very ideal for jewelry. It even dictates the higher prices than fancy shapes mainly brought about by higher manufacturing costs and more demands in the market.
It is noteworthy to mention also that while the demands for round cut diamonds is higher, the yield is basically lower. These two points contribute to the higher cost per carat weight of a round diamond. If the demand gets higher, the price automatically gets expensive. Whereas, the lower yield is mainly due to the fact that the round shape relies on the number of facets where the amount of rough stone is wasted to create a brilliant cut. Hence, the cost per carat of round diamonds is higher. The brilliance of round cut diamond is mainly affected by the mechanics of its shape allowing the maximum light to be reflected. Most of round diamonds carry 58 facets or flat polished surface. If the stone only has 57 facets then the culet is not present indicating small facet at the bottom of the diamond.
Fancy shape diamonds include all other shapes such as princess, emerald, asscher, radiant, princess, marquise, oval, heart and pear shapes. Getting a fancy shape diamond can give you more savings and an opportunity to obtain a bigger size and higher quality stone against your budget. Comparing the round diamond with fancy shapes, the cost of the round diamond will be about 25 - 35 percent more than the other cut diamonds. Yet, despite the costliness, round diamonds still dominates the market as the most favorite choice of diamond jewelry buyers.
