What does Romeo compare Juliet to? Act 1 49-58

Romeo compares her to torches and an African Jewel. Oh, she doth teach the torches to burn bright! It seems she hangs upon the cheek of night Like a rich jewel in an Ethiope’s ear, Beauty too rich for use, for earth too dear. So shows a snowy dove trooping with crows As yonder lady o'er her fellows shows. The measure done, I’ll watch her place of stand, And, touching hers, make blessèd my rude hand. Did my heart love till now? Forswear it, sight!
