I have used an antique silveroid pocket watch case and attached a glow in the dark compass, a black glass tile, an opal cabochon, an enamel guilloche blue rose square, a tiny brass key, a turquoise petit point cabochon, and other jewels inside. I then added assorted brass gears, Swarovski gemstones, a silver star charm, and other small jewels, and sealed the case with its original glass crystal cover. While the attached items remain in place, the other items are free to move about inside so the scene is constantly changing. Comes with a 24 inch silver plated snake chain.
