Do you have one of those diamond coated disks mounted on a mandrel usually included in those rotary tool kit.You could try grinding a flat spot on the ceramic ball so you can use your center punch,but I am pretty sure there will be a point where the disk will almost stop grinding.Another option is a belt grinder with a coarse grit belt.
As for a center punch, if you have some small diameter high carbon steel drill rods like O1.If so,you could make a hardened pointed punch,provided it is hardened and tempered right should be more than plenty to pulverize that ceramic ball.Held in some vise grip.
Also have you tried smashing the ceramic balls with a large hammer and an anvil
