The speaker seems to not be too pleased with the characteristics of the woman he is describing. He's saying her eyes are dull compared to the brightness of the sun, her lips are drab and have no color compared to red coral, her breasts are dun, her hair looks like wires coming out of her head, her breath stinks and that her cheeks have no color and are plain. I suppose in spite of all that he finds unpleasant about her, he still loves her and thinks she is rare and valuable.
