This box made of volcanic lava is topped with a sterling silver and crystal ball finial. The four silver circles are movable to create either a flat or three dimensional form. The interior of the box is lined with red leather. The box measures 3 1/8 inches square. It is 3 3/4 inches tall with the finial an additional 1 7/8 inches in height. This one of a kind sculpture is both beautiful and utilitarian. Made by Mexican silversmith Lila Parilla.
