I got a ring probably a year or so ago. It didn't cost much, less than $30, if I remember correctly. It was silver in color when I bought it, but when I take it in the hot tub it becomes a dull gray and loses its shine. After a few days of not being in the hot tub, it goes back to its original color. Then today I noticed that it had turned a new color. It's sort of a bright bronze color now, and around the words it's close to magenta. On the inside, where it touches my finger, it is still silver. What could this possibly be made of?
