Celebrating 10th Wedding Anniversary soon, need some ideas on gifts for my wife. Is it Tin or Diamond???
It’s both. Traditionally it was Tin. Modern times people have Diamonds. The color for this anniversary is blue or silver.
Perhaps give her a diamond anniversary band to add to her wedding set in a small tin with some candies?
