The Timmelsjoch is a well-known high mountain pass that links the Otztal Alps along the border between Austria and Italy. The pass has historically been an important route for travel and is now famous for its hiking, climbing and recreation options. The Timmelsjoch Experience was created to help promote the area and make it more accessible for tourists. As part of the program, there are a series of outdoor sculptures slated for the area and the first to be built was Garnets. Taking inspiration from the geological rock formations of the nearby valley, Werner Tscholl designed two pavilions shaped like faceted gems to serve as a viewing platform and exhibition room.

Inside, the exhibition room enlightens travelers about the environment, nature, geologic features, the history of the area, the culture of the communities and the economy of the region. Hikers and travelers along the road can stop to enjoy the sights or it can be accessed via bus and the sculpture serves as a creative bus stop. The exhibition room is built out of concrete with aggregate from the region while the pavilion is built from recyclable glass and steel. LED lights illuminate the sculpture at night and transform it into a glowing red cage.

As part of the Timmelsjoch Experience Werner Tscholl already designed the Passo del Rombo, the Timmelsjoch Experience Pass Museum.
