When Mirabella and Primula were preparing to leave Hobbiton to return to Buckland, Bilbo came with a small chest. "I have no use for these sorts of things," he said, handing it to Mirabella. "It came out of the Lonely Mountain, you know. The dwarves call them mere trinkets!"
Inside the chest was a small pile of gleaming jewels and delicate rings and bracelets and chains. "Oh, Bilbo!" Mirabella exclaimed.
"They'll make lovely birthday gifts," Bilbo said. "And perhaps something or Primula's wedding day?" His eyes twinkled as Primula blushed. "Drogo's a good lad. I'm very happy for you both."
