Product Insights
The Arch Onyx Sconce by Luminaire Authentik is a hand-carved, semi-translucent onyx wall fixture that produces a unique, volumetric backlit glow with two distinct light layers: forward diffused light from an opal glass globe and a backlit amber wall wash from the onyx backplate. Each piece is made to order in Quebec with diamond tools, featuring natural stone variations in veining and translucency, a Mohs hardness of 6.5–7, and an amber tone that deepens with age. It is dimmable with standard dimmers and high-lumen LED bulbs without glare, and its opal globe shields wiring and reduces dust. Priced at $555, it costs $175 more than flat-panel onyx designs, but delivers a richer, volumetric glow. Designed for commercial-grade hospitality, it is not recommended for high-humidity areas and requires care to avoid acidic cleaners.
