These earrings feature Swarovski ultra light blue rivoli crystal glass stones. I only have one of these stones left in my coveted stash. These pictures were taken using my new DSLR camera with a macro lens. I am in my trial and error stage and hope to determine the best F stop/shutter speed combination that works best. Photography is a great passion for me. Years ago, my husband and I had a darkroom in our home and developed our own black and whites. Good memories there!
