P.P.: I created this suncatcher with 76 5mm Swarovski Bicone crystals in shades of Lilac, Lavender, Blues and Greens. The outer circle measures approximately 2 1/2" and the inner circle swings freely as you can see in my photos. The center crystal is an exquisite 20mm Swarovski Strass faceted Crystal Ball. The entire length of the suncatcher, including the plated hanging ring, is 6 1/2".
