- Only Federico’s is selling AUTHENTIC TIME TURNER NECKLACE – All other sellers especially “Hogwart” in this same listing are selling cheaply made immitations. They are nothing but only low quality knock-offs. We (The Federico’s) are a small, London-based gift company offering unique presents for the sophisticated gift giver. We’re proud of our time turner necklace, and we want the planet to see it. Accept no immitations.
