The maximum diameter of the Berliner collar, including the pendulums, is 31.9 cm horizontally and 22.2 cm vertically. In its current state, it weighs 317.3g
The arrangement of the elements is determined by a sequence of letters: Α, Β, Γ, Τ, Ε, S, Σ?, Η, Θ, Ι and Κ.
Each letter was engraved on the plate, in the center of the trapezoid or crescent-shaped elements, and then covered by a frame.
The decoration of the central trapezium is unique, while two of the other sections each have the same frame system and the same filling motifs. These links are arranged symmetrically, starting from the central trapezoid.
