Best settings for a asscher cut centre stone
Four corner prongs or a bezel setting both work cleanly for an Asscher. A solitaire lets the asscher cut do everything; a halo adds a frame of smaller diamonds and makes the centre look 25–30% larger; a three stone setting flanks the centre with two accent diamonds.
