This magic necklace of pearls is perfect for any moment you are caught simply aghast. While worn, this necklace cannot be removed by creatures other than you. You can use this necklace as the material component for casting any spell which requires a pearl, but the pearls are never consumed by casting such a spell. 

As an action you can clutch the necklace with a free hand. While the hand remains on the necklace, you have advantage on Charisma (Performance) checks.
