Sapphire jewelry is the classic gift given on the 45th anniversary. There are many lovely styles to choose from in earrings, pendants, rings, bracelets, and cufflinks.
Dark blue home decor in crystal, artisan glass, or other sapphire-themed materials could be a great alternative if your wife is not really into jewelry.
Other options include pink sapphire jewelry, blue flowers, a love
poem on scented blue paper, blue clothing or other practical items.
We also really like the nostagic dvd and book (to the right below in the green column). They are particularly great for a party or get together of friends because it will jog everyone's memories. If you are looking for a permanent keepsake, the commemorative plate to the right can be personalized to the 45th anniversary.
If none of these items suit the recipient, you can substitute any kind of item. Just make it dark blue, or perhaps with blue ribbon wrapping. This is a great way to incorporate practical household or clothing items.
