The 45th wedding anniversary is referred to as the sapphire anniversary. Both modern and traditional customs call for giving a sapphire or something that is a sapphire blue color to those celebrating this milestone.
Modern and traditional monikers exist for various anniversaries, but many times the names differ between the two lists. Sapphire designates the 45th anniversary on both lists. A sapphire gemstone is appropriate for either a man or a woman. Sapphire necklaces, bracelets, rings and earrings all make wonderful anniversary gifts for the woman celebrating her 45th. For the man, appropriate gifts include a sapphire tie pin or cuff links. Less expensive gifts in keeping with the theme include pieces made of blue glass or crystal or blue decorative items for the home.
