I pretty much agree with all the other reviews.  The pendant is beautiful, although the sapphire is darker in color than in the picture.  I guess the color of the stones vary, as another reviewer said hers was lighter in color than the picture.
Although my chain was not knotted or tangled, it was too thin to hold this pendant...notice I said "was"...because I threw it away.  I bought a silver box link chain for $29, which looks beautiful with this pendant which is white gold, but nobody can tell the difference.  My necklace did not come in a pouch, as reviewer C. Stout's did, it came in a jewelery flip-top box.
