I purchased this necklace for my girlfriend for Valentine's Day 2013.  It arrived today and I took it out of the packaging to get a good look at it.

PROS:
-The heart shape is excellent and the pearl sits nicely in it.
-The pearl is perfect!  If there's a woman in your life who loves pearls, this is the necklace to buy her.
-The cubic zirconium gems look nice, albeit a little dull.

CONS:
-The chain is a little shorter than I thought.  It's shorter-looking than the diagram shows, but I don't think this is a real con.
-The heart is not solid.  It's more of a sterling silver casting.  It's difficult to describe, but if you turn it over, the metal is in a U shape underneath.

Additional info:
-The box that the necklace comes in is certainly not for display.  You'll want to find a nicer box to put it in.
-The blue bag that the necklace comes with is lackluster.  I set it aside for now.  I don't think it has a use with a necklace.

I give this necklace five stars because the cons aren't really a deal-breaker.  The pearl on the necklace I received is absolutely gorgeous.  My girlfriend will be thrilled.  Best of all, the price is right on this piece.  Definitely buy this piece for a girl that loves her pearls.
