The cube is small — at Dia 14 × H 20 cm, won't it feel lost on a large wall?
It's intentionally compact. The Magic Cube isn't designed to be the dominant fixture on a feature wall — it's designed to be a piece of jewellery on a quieter surface. Smaller spaces (a bookshelf wall, a corner above a console, a narrow hallway, beside a bed) are exactly where the proportions sing. On a large empty wall it will read as too small; on the right wall, the small size is what makes it intimate and considered. As a rule of thumb: place it where you'd hang a 30 × 40 cm piece of art, not a large painting.
Are Model A and Model B from the same design family, or two completely different fixtures?
Same family — same cube silhouette, same brass arm, same dimensions. The structural design is shared; only the glass motif inside the cube changes. Model A is a multicolour grid drawn from the geometric, modernist side of the Tiffany tradition. Model B is a folk-floral with two red tulips on an ivory ground, drawn from the European cottage-glass tradition. Owning one of each as a pair is a deliberate choice — they read as cousins, not twins.
How far does the brass arm extend from the wall?
The gooseneck arm projects roughly 20 cm (8″) from the wall plate, lifting the cube clear of the surface and into the room. This is enough to throw light across the wall (rather than straight onto it) and to read the four-sided glasswork from below — but compact enough not to interfere with bedside tables, narrow hallways, or doorway clearances. Confirm with your specifier that 20 cm of projection works for your placement before installing in tight passages.
The Rubik's-Cube look (Model A) — does it read as too playful for a grown-up interior?
It's playful but premium — the difference from a toy is the hand-pieced glass and the brushed brass arm, both of which carry weight even before the light is on. In a pared-back grown-up interior (limewash walls, oak panelling, neutral palette), a single Magic Cube becomes the room's punctuation mark — not the joke, but the wit. The look fails only when the rest of the room is already busy or themed; given quiet space around it, the cube earns its place.
Each cube is hand-pieced — what does that mean for a matched pair?
Subtle variations are part of the Tiffany tradition, not a defect. Two Magic Cube sconces flanking a bed will read as a coordinated pair — silhouette, motif, and palette are consistent — but a side-by-side comparison may reveal small differences in the cut of individual tiles or the precise tone of a single coloured pane. This is the signature of hand-pieced glass rather than machine printing. If exact symmetry matters more than craft variation, this fixture isn't the right choice.
