The 40th wedding anniversary is the ruby anniversary, so gifts in red such as wine, ruby red grapefruit, clothing and roses are good gifts for parents. Children who want to buy jewelry can give ruby earrings to their mother and rose gold cufflinks to their father. Another option is to plan a ruby red themed 40th anniversary party with the family.
A 40th wedding anniversary party should be decorated in red, with items such as balloons and streamers. Hosts can provide red and white personalized candy to guests as party favors. For their parents, children can play their parents' first wedding dance and other songs that were popular 40 years ago. Another memento of the occasion is a slideshow or scrapbook of the family over the past 40 years that can be shown to guests.
