Case study: custom black convex mirror for a Russian interior design client.

A high-end interior design company from Russia asked us for a decorative convex mirror to stand out as an artistic element in a luxury residential project. To meet both the visual and the durability requirements, we recommended 304 stainless steel with 8K mirror polishing and black PVD coating.

Key highlights

Material: 304 stainless steel

Finish: 8K super mirror

Coating: PVD black (graphite-like tone)

Application: custom-shaped convex mirror for interior wall decoration

Result: a striking centerpiece with lasting surface brilliance

The result

The client was highly satisfied with the surface clarity, the deep color tone and the craftsmanship. The mirror became one of the most talked-about features in the space.
