Chambered Nautilus Shell Appraisal

Framed Bisected Chambered Nautilus Shell Shadow Box

This decorative wall art features a genuine, bisected Chambered Nautilus shell mounted within a tiered, square shadow box frame. The piece displays the intricate mathematical Fibonacci spiral of the shell's internal chambers, known as septa. The presentation is modern, utilizing a dual-layered matting system; the top mat is a muted salmon or dusty rose color with a large nautilus-shaped cutout that reveals a deeper sage green secondary matting layer behind the specimen. The frame is a thin, metallic gold-tone finish, likely aluminum or gilded wood, which provides a classic 1980s or 1990s aesthetic. The shell displays a natural pearly luster on its interior surfaces. Regarding condition, the metal frame shows visible scuffing and minor finish loss along the bottom edge, consistent with age and shelf wear. The glass appears intact, protecting the delicate organic specimen inside. The construction indicates a mass-produced but high-quality decorative piece, typical of high-end home decor galleries from the late 20th century. The craftsmanship is evident in the precise mat cuts and the centering of the fragile shell fragment.
