Rainbow (soft rainbow colors with pastel Swarovski crystals). A rainbow signifies a promise or covenant. It can be an agreement made in relationships that are special to you. I have created these wings to represent a promise or an agreement made from one person to another. It’s a wonderful idea for example when a father makes a promise to his daughter that he will protect her during her life and this gift can symbolize this. A promise needs to be honored and we sometimes need to be reminded of what we agree to. This is a really nice way to encourage each other to keep to our agreements.
