These 14k Gold Leverback Earrings are featuring some beautiful created Opals.  Bright Red/Green/Blue Fire on a white translucent background. 

Totally gorgeous, and fraction of what real ones would cost -- but you pretty much have to be a jeweler to tell the difference.

The stones are set into bezeled cinchmounts, which are a good, stable mounting that doesn't set you back a month just to get a pair.
