The Ingravidesa Sculpture Alliance is formed by an international group of sculptors and designers who collaborate to create abstract sculpture inspired by nature. They often work together for months on monumental projects. The pieces are the result of collaborations where each artist and craftsman are invited to assist in the creation of these sculptures. Their mahogany and teak root sculptures often incorporate 18 carat gold or silver patterned layers. The wood is sustainably sourced and is primarily the roots of old trees, originally used in the timber industry.
