China is the traditional symbol of the 20th wedding anniversary, and platinum serves as the modern symbol. The emerald is the gemstone, and the flower is the daylily.
Appropriate gifts for the 20th anniversary include china in the form of place settings or decorative items or platinum in the form of jewelry, coins or decorative pieces. An arrangement of daylilies makes an excellent gift. Evidence exists that dates the giving of symbolic gifts on certain anniversaries back at least to the Middle Ages. Traditionally, only the biggest milestones, such as the 25th, 50th and 75th, were mentioned, but the 20th century saw the list of anniversary years given symbols expand to include many more. The traditional list included more practical symbols while the modern ones get a bit more extravagant.
