Love them, but delicate
I love these!  I bought them for myself a couple of years ago and wear them almost everyday.  They are small enough to be casual, but the opal makes them show up.  My only advice is to treat them gently.  After a couple of years, one of mine broke.  The circle that holds the stone broke off of the hook.  I ordered another pair and now have three good ones.  I handle them more carefully now.
