Jewelers will likely fix a piece if it’s faulty, but to keep your jewelry in top shape, it’s necessary to seek the correct care for the pieces you have, Pantin and Lampley Berens say. This is especially important when purchasing one-of-a-kind pieces, which cannot be replaced through any sort of policy since an identical item doesn’t exist. Additionally, it's important to analyze the warranty options when buying investment jewelry, like an engagement ring. Some sites offer packages that include yearly cleaning, complimentary sizing, or insurance.
