The choice of cutting depends on the crystal shape of the original stone. Most of the original stones are suitable for circular faceted cutting, which can best show brightness, fire color and flashing brilliance. However, a small number of rough stones with poor shape or deformation choose fancy cutting, which will have poor performance on brightness and fire color. Fancy cutting is expensive and time-consuming, and only a few experienced polishers can make it. Generally speaking, the price of fancy cutting fluctuates greatly. For the above reasons, manufacturers rarely cut and polish to produce fancy cuts. However, the 89-sided octagonal "Blue Flame" diamond launched by Tongling Store is very unique, which is a milestone in the history of diamond cutting. I suggest you enjoy it!
