The amulet of member of the Board of elders at Vittoria Vici (The Elder Scrolls 5: Skyrim)

Found in the pocket of Vittoria Vici Amulet of a member of the Council of elders. Searching about it online, can't find any information about where he got it, all information about it is associated with the quest of TB With the death of silence. I wonder what he told her? Interestingly, I brought this amulet to Delvin, but the dialogue about the sale has not appeared. I think to keep it ) Standing fashion worthy of mention: the Cutting Room Floor, Legacy of the Dragonborne. Anyone have any opinions about how he came to it and what the mod involved? I have a suspicion to the Heritage, he probably added it to her so that the player can pick it up for the collection. What are your assumptions?
