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.• Measurements: Small: 4" L x 1.25" W x 6" H • Medium: 6" L x 1.5" W x 8.5" H • Large: 8.5" L x 1.75" W x 10" H• Weight: 12 lb• Material: Onyx — warm and dense, with a mottled mineral character that deepens across the polished surface• Color Palette: Cream and ivory ground with warm amber and caramel clouding; tone and concentration vary across each piece• Surface & Texture: Polished throughout — smooth and continuous over the rounded form• Set Includes: Three sculptural onyx arch forms in small, medium, and large• Artisan Touches: Mineral pitting, veining depth, and amber concentration differ across each arch — no two pieces carry the same stone reading
