I did a little research on swarovski crystals. I found that even though they are lead based you can not be hurt by just wearing the crystals, and that the only way it would cause any harm is if they are consumed. Check out these webpages I found talking about the crystals.
In all it has made me feel a lot better about using these beads in my jewelry because I really do love them. They are unmatched in sparkle and color range and I would have hated to stop using them. Thank you to the two lovely ladies who commented on my last post your comments really mean a lot to me :-)
