Panopoly Savant: Crystal ball Divination Implement

[Kiba]

So, at level 8, a panopoly savant can use magic items at their caster level a set number X a day. with the mage's paraphanilia, one option to aquire it is to have a crystal ball implement for divination.

What magic items count as a crystal ball?

[Nixitur]

Well, I'm guessing that the Crystal Balls count as crystal balls. Eye of the Void is described as looking like a crystal ball, but that's a bit of a stretch.

I think the intent is just the obvious crystal ball items, but you might be able to argue for an orb of storms based on the material. Ioun stones would be a longer shot IMO.
