Three Small Beads, Cog-Wheel-Shaped

Three small, irregularly shaped beads against a black background. The bead on the left is a simple circle with a hole through its center. The other two beads are cog-wheel-shaped, each having four rounded protrusions around their circumference and a hole through their center. The beads appear to be made of a white or light-colored material, possibly metal or stone. The image is in black and white. The beads are by artist, Three Small Beads, Cog-Wheel-Shaped.
