Antico manufatto in pietra con motivo a nodo intagliato, bordi grezzi e texture minerali

Prompt

Create a photorealistic stone artifact with the logo of {LOGO} carved into the surface. The stone must have an irregular, fractured shape, with weathered edges and a raw, ancient look. The engraved logo should appear chiseled by hand, with deep grooves, rough tool marks, and natural erosion.
Lighting: soft but directional, coming from above, creating strong highlights and deep shadows that accentuate the relief.
Background: pure black to isolate the object.
Style: archaeological relic, primitive stone emblem, hyper-detailed mineral textures, matte surface, subtle cracks and dust.
Composition: centered, symmetrical or balanced, single object.
Render: ultra-realistic, high contrast, tactile stone material, no color except natural rock tones.
Format: 1:1, clean silhouette, museum-grade photography aesthetic.
