Very nice earrings. I really like the 12mm size in Blue. My earrings have almost no gold speckling which is just fine with me, but they are still marbled with deep and deeper tones of blue. So PRETTY. I am happy with my purchase, but have one concern. The wire that connect the heavy bead to the posts is extremely fine and I can't help but wonder how long it will last. I really wish that the wire used on these earrings was as thick as it looks in the picture. I have not had any issues with back on these earrings like other reviewers. The backs seem long enough, and they catch at the end so that you won't loose your expensive earrings.
