If they're good gems (rubies, star ruby earrings etc) you should rotate. If they're lesser gems such as peridots, jaspers, onyx etc nobody will blink an eye. I suggest keeping a stack of jaspers handy if people are asking for symbol and are not the main tank. They'll see the Symbol of Xx and be happy that you complied. Keep peridot symbols for people who need it.
