Realistic Rock Illustration - Free Clipart for Geology & Design Projects #273628 (License: Personal Use)

This grayscale illustration depicts a naturally shaped rock with realistic surface texture, including fine grain patterns and dark mineral veins. The stylized yet accurate rendering makes it suitable for textbooks, infographics, or digital assets requiring geological authenticity without photographic realism.

Used in educational websites, geology blogs, classroom handouts, or UI elements where a symbolic or simplified rock representation is needed-especially when color neutrality or vector-style clarity is preferred.
