Not really, they are two different things. If the Dev's meant for them to be the same thing then they would have called them the same name. Also Unaspected Crystals still have power in them, Deaspected Crystals do not. Hence why Beastmen can use the Unaspected Crystals to summon primals. I dont think you will be able to summon anything with a crystal that has all power drained from it
