This necklace was a surprise.  Despite the nice reviews, I was still pleased to see such a large stone.  It's particularly impressive for 25$.  The box chain is fine, but I'll probably switch the pendant between this and a 20" chain so I can wear it with different necklines.  Plus, if it's on a longer chain I can look down and see it, too.  The stone is a nice natural pale blue and catches light well.  This is a great deal for an impressive but inexpensive special occasion gift for your daughter/wife/girl friend/mother.
