I love seeing this wearable art, handmade jewelry on a silver chain. This piece features Swarovski clear crystals surrounding a spent ammunition shell primer end. The shell also has a clear crystal center. It comes on your choice of silver 1 millimeter snake chain from 16 to 24 inches. Default length will be 20 inches if no choice is made. Remember that there will be slight imperfections in the shell as it has been fired ammunition. Calibers may vary. Enjoy!!
