RONALD WESTERHUIS 'SUN' STAINLESS STEEL SCULPTURE: IDENTIFICATION

Measuring 1750 mm in diameter, this monumental spherical sculpture is executed in stainless steel (RVS) mounted on a square weathering steel (Corten) plinth. The primary surface features an aggressive, overlapping orbital-sanded texture that scatters ambient light, contrasting with deep, mirror-polished concave voids. These highly reflective cutouts invert and distort the surrounding landscape, actively shifting the viewer's spatial perception. The accompanying Collectie Harms Rolde placard confirms the creator as Ronald Westerhuis (Dutch, b. 1971), titles the work 'Sun', and identifies it as a unique uneditioned artwork ('uniek').

Compare with other artworks in the archive: Contemporary Wall-Mounted Convex Dome Sculpture with Mirror Inset, Guillaume Corneille (Dutch, 1922-2010) - Abstract Composition, Mixed Media on Paper, 1962, Contemporary Impasto Seascape with Pilings.

Ronald Westerhuis frequently utilizes offshore industrial fabrication techniques to manipulate heavy-gauge stainless steel into refined geometric forms. His work aligns with the optical interventions of late 20th-century reflective sculpture, though his deliberate juxtaposition of raw, abraded steel against flawless mirror finishes grounds the piece in industrial material reality rather than pure illusion. Large-scale public commissions by Westerhuis are placed globally, notably including the stainless steel volumes of the National Holocaust Monument in Amsterdam, completed in 2021 alongside architect Daniel Libeskind.

THE ART SPECIALIST'S TAKE

Museum-Trained Art Historian

Connoisseur

The presence of a direct gallery placard detailing the artist, title, dimensions, and medium, coupled with the highly recognizable signature style of the sculptor, provides near-absolute certainty.

KEY EVIDENCE

  • 1Official gallery label clearly attributes the work to Ronald Westerhuis, titled 'Sun'.
  • 2Label specifies dimensions as 1750 mm and material as 'RVS op staal' (stainless on steel).
  • 3The piece is marked 'uniek', identifying it as a singular creation rather than part of a numbered edition.
  • 4The combination of orbital sanding and mirror-polished concave spheres is the artist's defining technical signature.

WHAT WOULD IMPROVE CERTAINTY

  • →Confirm primary market pricing directly with Collectie Harms Rolde.
  • →Verify transportation logistics and base engineering requirements prior to any acquisition.

CONDITION & GRADE
