Were you a Chief Petty Officer in the Navy? Are you currently a Naval Flight Officer? Were you a Navy POW (Prisoner of War)? If you have spent any time in the Navy or you are in the Navy right now, you can also purchase a ring to help commemorate your time spent in this branch of the Armed Forces. Navy rings are about the same price as Marine and Army rings and come in the same types of metals as the Marine and Army rings. Men or women are able to purchase a ring to celebrate their time in the Navy.
