These are beautiful earrings.  I bought them as a birthday gift for a friend who has those pretty light blue eyes and she liked them so much she took off the earrings she had on and put these new ones on right away.  They are just the right size - I would say about a half inch in diameter - and a very nice light blue color, just as pictured.  I was afraid that with the lever backs, they might hang down too much to be seen, but they don't - the stone sits right below the earlobe and faces straight out - they are just perfect.  I highly recommend them.
