Appearance and size


The shape of a lab diamond can make it appear larger or smaller, in certain cases. Sometimes diamonds are positioned with their table facing upward. For shapes such as emerald or asscher, it means they may not look as large as other diamonds with the same carat weight. Expert jewelers suggest that in order to maximize size relating to carat weight, one should choose princess and marquise cut lab diamonds.


The price factor


Certain shapes of lab created diamonds are more affordable than others. Fancy diamonds cuts such as oval and emerald are more affordable compared to the most popular – round shaped diamond. The reason: less of the diamond rough is likely to be wasted if cut into a fancy shape. This allows a larger carat weight in the finished stone.Shapes such as heart and pear can be selected in order to remove significant inclusions from the rough diamond. In this way less of the rough diamond is wasted.


Personal taste


One may consider factors such as affordability, size and appearance, but one should always choose the shape that one likes and the one that matches your personality. Buying a diamond is an investment, and one should be sure that s/he is going to like it and wear it. So you might not want to disregard a certain shape just to save some cash.
