The traditional gift for a 30th anniversary is pearl. Some ideas for a 30th anniversary gift are a pearl pendant, necklace, bracelet, ring or cuff links.
Pearls are sensitive and require special care and cleaning. Makeup and perfume must be removed from pearl jewelry regularly, and pearl necklaces need to be restrung every few years. The modern gift for a 30th anniversary is diamond. Diamonds may be a more desirable gift because they are more durable than pearls and require less meticulous care. The flower commonly associated with the 30th anniversary is the lily. A bouquet of lilies and a piece of pearl or diamond jewelry can symbolize the enduring love of a 30th anniversary.
