Eight hearts and eight arrows is the effect of diamond cutting, which is popular in the market now, and it can also be said that it is a gimmick of merchants. There is also that eight hearts and eight arrows are not necessarily easy to cut. I mean, the cutting of EX will definitely have eight hearts and eight arrows, but the diamonds with eight hearts and eight arrows are not necessarily the cutting of EX, and EX is the most important thing. (Note: EX stands for perfection, and the cutting work is divided into EX VG GD at one time. You don't need to consider buying it after GD. )
