I was not expecting that the pendant is small.  I thought it would be big enough to be as noticeable as possible.  I also thought that it would suit my age but it turned out that it's cute and a nice gift for kids or teens.  I think that the size of a necklace or pendant should be best described in a picture with a model wearing the item.  This way, you can estimate its true size rather than just describing it by measurement. Some do have pictures, but others don't have.
