The stone is a pretty deep shade of blue.  This is the second heart shaped Queenberrry Swarovski pendant on a leather necklace that I've bought.  The first was the vitrail light (also very pretty).  The stone is a good weight and I love the adjustable strap.  It is easy to get on and off and I can make it exactly the length that I want it to be.  GREAT PRICE for a nice casual piece of jewelry.
