How can you tell a vintage pearl necklace?

To determine whether a pearl necklace is modern or vintage, first look for signs of wear, such as blunted edges on the prongs. The pearls will likely have dull spots where they came into contact with skin. The clasp can clue you in, too. Lobster clasps appeared in the 1970s, while early 20th century clasps were generally safety-pin style or C-clasps. Modern necklaces typically have a spring-loaded clasp.
