Rock Illustration - Free Vector Graphic for Design & Education #3839071 (License: Personal Use)

This stylized rock illustration uses layered gradients of gray-from light highlights to deep shadows-to simulate depth and texture without fine detail. Its irregular, naturalistic silhouette suggests a sedimentary or metamorphic stone fragment, suitable for scientific, educational, or graphic design contexts. The clean isolation on black enhances versatility for overlay or compositing.

Commonly used in educational websites, geology apps, children’s science books, or as placeholder art in UI/UX mockups where a neutral, nature-related icon is needed. Matches user intent for free, royalty-free rock imagery for non-photorealistic projects.
