Annatar’s Mithril Pot - Lord of the Ring: The Rings of Power
When an almost exasperated Annatar went to Khazad-dûm to ask for more mithril, he was turned down. King Durin wanted to hold out until the Elves of Eregion were truly desperate since he could then trade the mithril for something far more valuable than the lumber Annatar offered. 
This meant that the Lord of Gifts had to return to Celebrimbor empty-handed. Despite this, Annatar whipped out a vessel filled with ground mithril (refined to a powder by Narvi) and handed it to Celebrimbor after convincing him that the only way forward was with their Nine Rings of Power.
Moulded and cast using crystal clear resin, a 24karat gold leaf surround and a stash of your very own Mithril! 
These pieces are all hand made to order so wait times can vary.
