The fundamental building element of silver jewellery is the equilateral triangle and spatially, the tetrahedron. It can be found in the structure of many crystals and molecule models and combined into infinite spatial shapes. The tetrahedral structure with flexible joints forms various shapes of mobile adjustable jewellery. Despite the geometrical structure it gently follows the motion of a body. The illusion of infinite structures symbolically alludes to permanence. The gleam of the pyramidal peaks is highlighted by the embedded ground glass stones.
