3D Laser-Engraved Crystal Ornament Generator

A comprehensive, structured prompt defining an AI role as an expert product photographer and art director. It instructs Nano Banana Pro to generate a photorealistic image of a custom 3D subsurface laser-engraved crystal ornament based on a simple subject or an uploaded image. The prompt includes detailed logic for autonomously determining the crystal shape, base material, environment, and lighting to best complement the subject's 'vibe' (elegant, cozy, dynamic), ensuring the final output adheres to strict technical specifications for realism.
