Cast Metal Puzzle Level 8: Ring

This 3D metal puzzle by Hanayama Huzzle is designed to resemble a miniature ring, with detailed craftsmanship and a sturdy metal construction. This puzzle is based on an original called the Puzzle Ring. Popularized in 15th century Europe, this ring style was actually used for official engagement and marriage rings. It is rumored to prove as evidence of its wearer's adultery - when it comes apart into pieces.

The ring separates into four pieces but remain interlocked. Your challenge is to put the pieces back into the original ring shape. With no instructions or obvious solution, you'll need to use your wits to figure out how to assemble it. Perfect as a gift for the puzzle lover in your life or a challenging treat for yourself.
