I may be a vintage marble. I may be a game piece. I may be something else entirely. I am as unique as my wearer, and always ready to be a conversation starter. *Pendants have a wire wrapped stainless steel cap. *Comes on 18" black cord necklace with length adjustor chain (included in measurement) and lobster claw clasp. **Please excuse any reflections in the shiny surface of the photos. Note: Vintage marbles, etc. have "character marks" associated with time and use. They are perfectly imperfect. Some are more scarred than others. If you have questions, don't hesitate to ask. No two are alike although some may be similar. Marbles vary in diameter. Marbles and game pieces average about 1/2 to 5/8 inch in diameter.
