I bought the Style K3, which appeared to be from the pictures, Black Lenses with Silver Embellishments. I received my order yesterday, 8/21/2015, and when I opened the box, the glasses were as nice as they are shown in the advertisement, however I was under the impression, that I was getting Silver and not Gold, The Style K4 also say's Black Lenses, but nothing about the embellishments. which I am wondering if, they are Silver which is what I wanted :( I guess I will just keep them, because they are nice sunglasses, but I think the seller should state in their advertisement, that the K3 has Gold Embellishments, and the K4 has Silver, I guess??
