Coral Anniversary What Could I Buy My Parents For Their 35th Wedding Anniversary?

What could I buy my parents for their 35th wedding anniversary? - coral anniversary

There are five kids in my family, so he could very well together and do something good. His birthday is not until May, but I like to plan the future. Are you planning an anniversary trip, we can not do. I really want nothing to do with coral (which is the gift of the 35th), but I want something beautiful / unique. Has anyone an idea?
