3D icon of a gray, round, flat stone with a rough, textured surface. The stone has irregular circular lines and natural rock patterns, located in the center of the composition without any secondary elements or background. The stone should be rendered in 3D with smooth yet realistic surface discontinuity and a minimalistic color palette that replicates the natural look seen in the image. The lighting should be soft and diffused, highlighting the texture of the rock without creating harsh shadows. The edges around the circumference of the stone should appear slightly worn and uneven, contributing to the overall natural feel of the object. White background, centered, no shadow, clean icon style, high detail, 3D render.
