Arkenstone

Heart of the Mountain.

Kingstone.

It was a great white jewel with its own inner light, shaped like a ball with thousand facets, shining like silver in the light of fire, like crystal-water in the Sun and like snow in the light of Stars and like rain in Moonlight. It caught light and transformed it to ten-thousand rays with a touch of the colors of the rainbow. Indeed this was the Kingstone, the Heart of the Mountain.

The approximate size of it ; too huge for a hobbit-hand to close around it, yet it could be hidden in a deep pocket.
