And that's the standard result from an ordinary failure with Quick and Dirty enchantment:

3rd edition:

A failed roll means that the enchantment on the item is perverted in some way, or is an entirely different spell — GM’s choice. The caster will not know his spell went wrong unless he uses Analyze Magic or tries the item!

4th edition:

On a failure, the enchantment perverts in some way. It might acquire unpleasant side effects (see the Random Side Effects Table, p. B479), become an entirely different spell, or anything else the GM likes. The caster won’t know his spell went wrong unless he uses Analyze Magic or tries the item!

I should have been more specific in my statement - as the topic of this thread is structuring powerstones...

Per GURPS MAGIC, a critical failure DESTROYS a powerstone.
