This design is available at Tiffany's.  You can see it buried in their website under hundreds of earrings, but ofcourse with real pearls and a real diamond, both of high quality.  These ear-rings, for the price are good quality and look expensive!  The backs are delicate but sturdy and the zircon is big enough to show.  The shell pearl is also well crafted, and can pass off as the real thing.  The size of the pearl is a tad big for my taste, as I prefer understated elegance. But then it clearly states 8 mm and it is 8 mm.  I think 6mm would have been perfect, but even this size works right for any occasion.

Good Buy!
