Received these super quick. Remember, this is a pearl, and the dyed color will vary. Mine happen to be a bit more "blue", than gray with greenish overtones. Even though they are not exactly the same color as my tin cup gray/blue pearl necklace, they work well together. The size is exactly what I expected. If you have longer hair, or hair that moves in front of your ear a bit, you might want a pearl that is closer to the 9mm size. I wear my hair in a pony tail, so this size is fine for me. We've all had posts, where the butterfly back is not snug, so I was a bit cautious about what I would receive. i found the 14K gold butterfly is nice and sturdy, and the back slides onto the post, nice and snug - great! These earrings are idiot proof, everyday, grab and go. That extra little sparkle, really gives them a little bit of light, that a plain pearl stud doesn't have. Definitely a keeper. They are fairly priced as well - and I am a big time comparison shopper.
