Golden Ratio Seashell Spiral on Turquoise

Pale, creamy ridges curve inward along a precise logarithmic spiral, revealing the calcified interior of a seashell cross-section. The shell rests against a wall of peeling turquoise paint, where layers of weathered pigment expose rougher gray plaster beneath. Soft, diffused light fills the indoor space, bouncing off pale surfaces to eliminate harsh shadows. The shell's glossy surface catches faint, blurred reflections of the surrounding room. Microscopic textures define the shell's edges, against the coarse, flaking paint. A small chip in the turquoise layer sits just inches from the spiral's center point.
