The Half Moon Diamond Cut
The benefit of opting for the half moon cut as side stones is the fact that there is no need to overcomplicate the qualities of the stones. Since they will be significantly smaller than the center stone, you can easily get away with opting for a lower clarity rating and a lower color grade. This makes it relatively affordable to add half moon cut diamonds as side stones to your engagement ring. If you do prefer a larger size, then you may want to consider increasing these qualities a little to avoid the side stones is a mismatch to the center stone.
