Black Diamond Castle Ring

If you're too humble to claim the entire solar system--including Pluto--revolves around you, project smaller-scale dominance by becoming King of Theo Fennell's Castle Ring. This intricate, hand-crafted medieval fantasy is made of 18ct Yellow gold molded as a brick castle and topped with a 23.88ct black diamond. But the real "draw" of the jeweler's piece of royal fashion for the finger? A functional draw bridge with chain mechanism that opens to reveal the castle inside.

Fennell's design is available by request. So is its price. Good luck crossing that bridge.
