This is the pièce de résistance. Featured on the runway at the 2025 Bridges Conference Math + Fashion Show, the Chessboard Necklace is created in White- and Black-Rhodium Plated Brass. It pairs with the Knight's Tour Cube Earrings. This piece is unique.
The Chessboard Necklace is made up of two layers. The bottom layer (in white rhodium plated brass) is a comprised of squares that form a shape reminiscent of a crescent moon. The top layer (in black rhodium plated brass) overlays a path that zigzags between the centers of the squares.
On a chessboard, a knight moves diagonally along a path shaped like an L. A knight's tour is a walk visiting every step of a chessboard using knight's moves. This is possible on an 8x8 chessboard, and on the modified chessboard of this necklace. There are not as many possible knight's tours of this modified chessboard; an asymmetrical one was chosen to capture the viewer's interest.
The pendant is 4.4” (11.2cm) wide. The contrast between the white and black rhodium evokes the coloring of a classic chessboard.
The pendant is created through a lost-wax casting process, with molten brass replacing a high-resolution 3D printed wax model, white and black rhodium plating applied, and completed with a sterling silver chain.
