Bullet Jewelry 9mm Bullet Ring that's fully adjustable with silver plated band I have many colors available, including birthstone colors. This is a 38 Special caliber adjustable ring and is accented with a clear crystal in the middle. This piece is made from Nickel plated bullets that have been tumbled clean and polished with a cloth to give a nice shine. Each piece is hand cut and crafted, so there may be subtle differences than what you see in the photo such as head stamps or markings. If you want a specific brand of bullet, please contact me and I can see what I can do.
