I'm getting ready for another show and thought I'd put some of my items up before I forget how I made them. I used genuine Swarovski 5601 Alexandrite - 6mm - coupled them up with some Swarovski 12mm  cubes and square rhinestone rondels. They measure 1 5/8" long including the hooks. Thought they came out rather nice. I shot them inside and out so you could see how the colors change in the Alexandrite'ss.
