Ancient Hand-Chiseled Stone Artifact Logo

Create a photorealistic stone artifact with the logo of logo_name carved into the surface. The stone must have an stone_shape, with edges. 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.
