USN INSIGNIA LOCKET (NO CHAIN) OPENS FOR HOLDING TWO PHOTOS

I WAS TOLD THIS WAS SILVER WHEN I PURCHASED IT. IT IS NON-REACTIVE TO MAGNETS AND I BELIEVE IT IS SILVER. THAT SAID, I CAN FIND NO MARKINGS. IT MAY BE THAT WEAR HAS JUST MADE THEM INDISTINGUISHABLE. PERFECT GIFT FOR NAVY SWEETHEART OR WIFE!!!
