Modular Ring Series takes its cues from contemporary sculpture, melding art and design through wearable objects. RIIA designs begin with blocks and grids, and from there explore the possibility of play through asymmetry, repetition, and moments where elements of a piece interact through movement, weight, or points of contact. RIIA pieces engage a meditation on form, the simplicity of the shapes and materials emphasized by careful artisanal construction.
