Vintage Richelieu Pearls

Vintage Mikimoto pearls are set with cream or white pearls. Colored pearls are a modern addition. All Mikimoto pearl jewelry includes marks on the back or inside of the piece that is either the Mikimoto name, an “M” logo or the outline of an oyster. In addition, strands of pearls will have a dangling “M” charm. Mikimoto stores and authorized retailers will also appraise and issue a certificate of valuation for any Mikimoto piece.

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.
