At first I read the reviews for this particular opal necklace. A lot of them were negative comments, but I have always taught myself to go off of my own judgement, and if I do not like it, then I can simply return it for a refund!!!!! So you have nothing to loose!!!! Glad I didn't listen to some of the reviews because it is absolutely gorgeous with a glistening sparkle!!!! This is my first birthstone jewelry and I am so proud!!!!! Blue Nile never disappoints!!!!!
