Conversations with Magic Stones (Magic Stone Three) is a public art work by English artist Barbara Hepworth located at the Lynden Sculpture Garden near Milwaukee, Wisconsin. The sculpture is an abstract, modified cube form made of bronze; it is installed on the lawn. Originally, this work was created as part of a multi-part sculpture with two other bronze "magic stones" (eight-sided polyhedrons) and three "figures" (vertical abstract sculptures). One of these other works, Conversations with Magic Stones (Figure Three), is also installed at the Lynden Sculpture Garden.
