Three arch sculptures in graduated sizes, each shaped from a single piece of onyx into a full rounded form — two cylindrical legs rising to a continuous curved apex. The stone is warm and mottled, cream and ivory ground with amber and caramel clouding, visible mineral pitting across the polished surface. Each piece carries a different concentration of tone.
On a low console in a wide entrance hall, the three arches are arranged as a group — the largest at the back, the smallest in front. They are placed and left. The graduated scale reads clearly from across the room, the smallest arch holding its place at the front without being lost beside the others.
