This small gemstone is made of either jade, ruby or diamond featuring an arcane symbol etched into it. The stone is commonly set in jewellery such as a ring, bracelet or amulet. The stone holds one charge and once attuned you can expend the charge to cast the spell Find Familiar as an action (instead of the normal casting time) without the need of spell slots, components or knowing the spell. The familiar's type will be decided by the type of stone: Fey for Jade stones, Fiend for ruby stones and Celestial for diamond stones. The familiar is summoned at maximum hit points.

Once the charge has been expended roll 1d10 at dawn. On a 10 the charge recovers otherwise it does not recover. If the charge has not recovered after nine consecutive dawns then you automatically succeed on the roll for the tenth dawn.

If the stone is ever not within 30 feet of you while attuned then the familiar is temporarily dismissed until you are back within 30 ft of the item and use your action to summon it back. If your attunement ever breaks the familiar is dismissed permanently. (See the Find Familiar spell's information for details on dismissing the familiar).
