I'm not an expert - just a 60 year old grandma. I love my pearls. They may be "included" (see rating below), but I couldn't see any defects. Of course, I don't have a jeweler's eyepiece or any other type of magnification, so what I see with my bifocals is it. Use a little common sense. My advice is this - if all you have on your dresser is a little wooden jewelry box, then you will be pleased. If, however, you keep your jewelry in a safe, then these pearls are not for you.
