The pendant is 5/8" in diameter, has a nice weight to it and rests well on the chain. She really likes it and best of all, I have gotten calls from people that she has ran in to asking where she got it. Frankly, I didn't tell her I got it on Amazon because I didn't want her looking it up and seeing how inexpensive it is! Childish, I know. I would recommend this necklace, especially for the reasonable price.
