Crowsight

Peering into the eye, your vision shifts temporarily to be like that of a crow's. You can pinpoint, by sight, the location of any precious metals and stones, such as coins and gems, within range. If a precious metal or stone is being worn or carried (such as in a coin purse or in the form of jewelry), it briefly flashes for you upon first glancing at it, and you have advantage on Intelligence (Investigation) checks made to track down its whereabouts should you lose sight of it.
