Verre Églomisé, Art Glass & Luxury Decorative Finishes

Diagonal is particularly known for verre églomisé and art glass, including custom mirrored panels, architectural art glass, water-gilded mirrors and hand-finished surfaces.

Our collection extends across multiple disciplines of luxury decorative arts, including bas-relief, chinoiserie, raised lacquer, hand-painted wallcoverings and Tibetan knotted carpets, allowing designers to source distinctive materials that are not available through design centers or retail channels.

A Trade-Only Resource for the Design Industry

Diagonal was founded to serve the professional design community.

We work exclusively with interior designers, architects and top design professionals, protecting the relationship between designer and client while providing access to materials that are highly specialized, technically demanding and impossible to source through ordinary retail channels and design centers.

Our role goes beyond simply supplying materials. We provide deep technical expertise, specialist knowledge and exceptional service, helping design professionals identify the right material, finish for a range of applications with door to door white glove delivery and qualified installers. We are industry compliant with $4 million umbrella insurance and are an approved vendor for leading hospitality companies.

High-End Residential · Yachts · Hospitality · Retail · Architectural Interiors
