Your spouse and you have been through thick and thin. 25 years and still making it stronger and full of love! The perfect gift is a lot harder to find now since you have almost given everything?
It must be a gift made of silver, now just choose from among the silver things you see in stores or online. Can you find the perfect silver gift to your spouse? Since she's always in the kitchen, can you look for silver themed kitchen appliance? Try to ask the stores if they offer silver table runners. The silver dining ware can be used on your 25th silver anniversary wedding dinner. Make your gift truly unique by designing it and making it personalized.
Giving her silver accessories only strengthen your relationship as she remembers you everytime she wears them. Rings, bracelet or earing are good silver gift ideas. Have your initials engraved on a pair of rings so you can have something to wear together. This is something you can wear for such a long time and all the time unlike diamonds or gold. Look for sterling silver if silver is something you do not find appealing.
Another option is sterling silver! You've exhausted all your resources and still was not able to buy a silver gift, then just buy her a bunch of flowers! To represent silver anniversary, buy her a bunch of Iris. She can't resist the flower and the chocolates. Look for accessories that will match your bouquet of flowers and chocolates if you may.
Fresh flowers would wither but accessories don't, so why not look for any object related to iris instead? Flowers on top of the luggage will do the trick and would mean you're leaving for vacation? Away from work, so do not worry about anything else aside from just being with your someone special for 25 years. This should be a big event for you too! Fulfill your life long dreams of going away to your dream vacation!
