Joe Marshall, the youngest son of Mike Marshall, is following in the footsteps of his very creative father! Joe lives with his father on the Rosebud Reservation here in South Dakota. These dentalium shell earrings are the first pieces we have purchased fromt this budding young artist. Beautifully made and very authentic. Dentalium originates in the Northwest Pacific coast and was a highly desirable trade object for the people who lived here 1,000 years ago.
