This jewellery box is a handmade piece, crafted out of wood and veneered with olive root and ebony. Due to the symbology of the Platonic solid used to build the lid of the jewellery box, the regular icosahedron, the author called it Symbol of Water.
Geometrically, the Symbol of Water is formed by a regular pentagonal prism - the body of the jewellery box - and a regular icosahedron - the lid. In the closing process, the icosahedron is partially introduced into the pentagonal prism, with one vertex lying inside the body of the jewellery box, six vertices coinciding with the vertices of the upper base of the pentagonal prism and the remaining vertices on the outside. The icosahedron is only fully visible when the lid separates from the body.
