DON'T GET TOO EXCITED- this is synthetic opal and it would HAVE to be at this low price. It is set gold plate with cubic zirconia on a 14k gold plated ball earwire. SEE THE VIDEO ON INSTAGRAM. I attached color change alexandrite briolettes. I just have one pair like this. I could do more upon request if I get more evil eyes. The length is about 1.75" Your jewelry will arrive beautifully gift boxed.
