Alexandrite's - one of my favorite Swarovski items - if you note the configuration in the pictures they are identical - one is with fluorescent light one is with regular day light. Amazing right? I want you to see the difference. These are not very old - made in 1998 still in the original packaging (you don't get that). You are purchasing a lot of 24.
I actually have a huge hoard of vintage Swarovski beads that I have collected over the year (50 actually) and since the old fingers don't work so great anymore and the eyes well we won't talk about that - well time for me to start moving them along to other bead lovers.
