Instant Summons
Any time after, you may crush the stone and speak the name of the item, summoning it instantly into your hand no matter the physical, metaphysical, or planar distances involved, at which point the spell ends. If another creature is holding the item when the stone is crushed, the item is not summoned to you. Instead, the spell grants you the knowledge of who possesses it and a general idea of the creature's location.
Each time you cast this spell, you must use a different precious stone.
Dispel magic or a similar effect targeting the stone ends the spell.
