It should be free or nothing at all...yellow diamond only adds +8, there are much better spars than that. For example, nimbus spar from big magical eggs, or even spars from quests.
Once u apply the yellow diamond, u can't take it out without a tear plier, which cost im. So i don't think anyone would want a yellow diamond, i would just suggest u to throw them out or something.
