This is a hanging window treatment - suncatcher - measures an overall length of 7" long. The big crystal I used is genuine vintage Swarovski Art 39 18mm. I also a smaller Article 5004 12MM on the middle. I used a couple vintage sun findings above and below. Of course this piece is a one and only as no 2 strands I make the same. Price is firm on this one - hang it in a window with good sunlight for maximum sparkle.
