This ring is made out of the end of a bullet shell casing. Send me your Ammo and I'll make you jewelry out of it. This is made of brass and reads: 9mm WIN (for Winchester) Luger. The ring band is made of stering silver and the 5mm stone that is set in center is a Zirconia. Price varies by type of stone in center. Send me your shell casing and I'll make you the ring or a bracelet!
