To what does Romeo compare Juliet in Act 1 Scene 5 of Shakespeare's Romeo and Juliet?

In Act I,
Scene V of 's, the young son of the patriarch of the Montague clan has
sneaked into the Capulet's formal ball along with his friend and cousinand friend .is determined
to observe Rosaline, with whom he is more than a little infatuated, but knows that the Capulet
estate is forbidden territory for a Montague. While immersed in the scene, Romeo spies a young
woman who makes him forget about Rosaline: . Upon first observing this beautiful young woman,
Romeo inquires of a servant, "What lady is that, which doth enrich the hand Of
yonder knight?" To the servant's declaration of ignorance, Romeo then makes the
following comment regarding the fair Juliet:

O,
she doth teach the torches to burn bright!

It seems she
hangs upon the cheek of night

Like a rich jewel in an
Ethiopes ear;

Beauty too rich for use, for earth too
dear! So shows a snowy dove trooping with crows, As yonder lady oer her fellows
shows.

Romeo succeeds in making Juliet's
acquaintance and the mutual attraction is immediate and intense, although Juliet plays coy in
the beginning. As the scene nears its end, Romeo makes the following comment to Juliet, in which
he compares himself to a pilgrim visiting a shrine:

This holy shrine, the gentle fine is this:

My lips, two blushing pilgrims, ready stand

To smooth that rough touch with a tender kiss.

So, in rapid succession, and withtrying desperately to convince
Capulet to expel this intruder, Romeo compares Juliet to a rich jewel and a holy shrine, in
addition to making other comments intended to convey the intensity of his feelings for the young
woman upon whom he has only just laid eyes for the first time. The intensity of his feelings for
Juliet, and her's for him, sets the stage for the fateful chain of events to
come.
