The Birthday angels represent the birthstone color of the month. Each angel holds a colored heart shaped crystal. The skirt is made from white iridized glass and the wings are metal filagree with a wire halo. They are made to stand on a metal base, but it is possible to hang them in a window if you wish using our medium suction cup AC-2055-1. All of our giftware in made using real stained glass. The metals are nickel plated to add extra strength and lasting brilliance.
