granite bollard sphere 3d model

A realistic outdoor granite stone ball bollard, consisting of a large smooth stone sphere mounted on a short round cylindrical base. The sphere and base are made from the same light gray granite material. The surface is covered with dense black, dark gray, and white mineral speckles, forming a natural salt-and-pepper granite pattern. The stone should look heavy, solid, durable, and suitable for outdoor public spaces such as sidewalks, plazas, parking lots, and building entrances. Use a matte or lightly polished stone finish, not glossy or reflective. Add subtle roughness, fine bump texture, small surface irregularities, and natural variation in the granite grain. The material should look like real weathered outdoor granite with slight roughness and realistic mineral flecks across the entire surface.Light gray speckled granite material, dense black and dark gray mineral grains, white stone flecks, natural salt-and-pepper granite pattern, matte rough polished stone surface, subtle bump
