A wedding anniversary color chart is available from Anniversary-gifts-by-year.com, as well as a list of gift suggestions, flowers and gemstones traditionally associated with each anniversary year. There is also a list of gemstones organized by anniversary year along with pictures and color descriptions available from Anniversary.us.com.
Each anniversary of a couple's wedding traditionally has a different theme and gem associated with it. Generally, the value of gifts and gems increases the longer the couple has been married. Especially notable years include the first anniversary, fifth, 10th and 50th. Themed years are counted every year up to 25 years, after which a special theme is only associated every fifth year.
