Greek artist Eleftheria Stamati's metal necklace pendants resemble outlines of three-dimensional Tetris blocks.
Stamati's collection, named The Mechanics of Black, features different flat shapes formed using thin pieces of metal.
The lines are carefully arranged so their angles and varying thicknesses create the illusion of a 3D drawing showing a simple architectural volume.
Stamati played with perspective, vanishing points and mathematical geometry to produce the designs.
The shapes include cuboids, a cube and various L-shapes, similar to the 2D polyomino blocks – geometric shapes composed of squares connected edge to edge – used in the Tetris puzzle video game.
"I design and create jewellery while thinking as a sculptor," said Stamati. "I consider space as a bulk of matter on which I interfere by removing pieces until I capture the ideal final shape that merges luminosity, harmony and effortlessness."
Each necklace features two pendants, which are intended to sit on the wearer's chest and upper back.
For every pair, the design at the front is an opposite to, or a variation of, the rear version. The pendants are connected by thin chains that drape over the shoulders.
