Upon receiving these from Amazon, I was very pleasantly surprised at how beautiful the earrings were.  The created opal is beautiful, with lots of color and sparkle going on within the well sized stone.  The setting was done extremely well.  The only thing my daughter had a little trouble with were the small backs.  I would have liked to have seen a little bit bigger back for the post.  A minor issue.  2 thumbs up for these earrings!
