Graph theory is the study of connections and networks. These earrings show two special graphs - the complete graph on five vertices (k_5) and the complete bipartite graph with six vertices (k_{3,3}). Together they give complete information about when a graph can be drawn on paper without crossings. This is known as Kuratowski's theorem. Even though they can not be drawn on paper without crossings, these earrings have been designed to have no intersections.
Our nylon jewelry is created through a laser sintering process in which the model is fused together one layer at a time from white nylon powder. The jewelry is then dyed to give it its final color.
