Marchetti Diamante Decorative Wall Light

The Marchetti Diamante Decorative Wall Light, designed by Roberto Giacomucci for Marchetti, is a wall-mounted decorative luminaire that pairs a modern wrap form with traditional crystal detailing. It is conceived for interior ambient and accent lighting, offering visual interest whether lit or unlit.

The design comprises three overlapping horizontal bands of faceted crystal arranged in an asymmetric, wrap-around composition. The Diamante is offered in a crystal appearance and the layered form intentionally obscures the source to create a sculptural wall presence.

The visible construction combines dense, multi-faceted transparent crystal beads with a polished chrome or silver-toned internal structure and mounting elements. The high-texture crystal surface reads as decorative even when the light is off.

Light is directed through the crystal facets so the fitting refracts and splits light into a subtle, shimmering spectrum while reducing direct glare. The layered bands also cast decorative patterns onto surrounding surfaces, making this suitable for ambient or accent use where atmosphere and detail matter.

An integrated metal wall bracket secures the assembly to a vertical surface and the open-ended curved form allows access for maintenance or bulb replacement from the top or bottom. Note the fitting is IP20 rated and intended for dry interior locations.

At Lighting Design Online we frame the Diamante as a design-led choice for interiors where considered ambience and craft matter. We provide practical, project-friendly guidance — from selecting the right mounting location to confirming compatibility with your lighting scheme — so the finished result feels intentionally balanced and long-lasting.
