Just out of curiosity did anyone manage to pick up the diamond that was in the kettle near the chest in Pinepeak Cavern? It moves nicely around in the kettle, but you cannot pick it up either in the kettle or after you take the kettle. Such a pity the pretty sparkly diamond has to stay uncollected, at least on the Xbox 360 version.
I missed Pinepeak Cavern the first time, not being that up on the map hints when I went to see the greybeards the first time I never noticed it reasonably close to the bottom of the stairs.
