Beautiful crystal jewelry, crystal flowers, or a figurine of the recipient's favorite animal would make a nice gift. This is traditional so one does not have to stick with tradition and choose any nice gift for the couple. Some people don't care for crystal so it's best to make sure before you purchase an item.
Roses are this anniversary's flower , so pick her favorite color. A dozen or an arrangement with roses dominant.
There is no actual gemstone for this anniversary, so choose what you like if you want.
