sterling silver dainty heart pendant on sterling silver chain.  the heart has a smaller purple heart stone in it. not sure exactly what it is, but it sparkles too much to be glass, so I'm assuming its crystal.  might be synth rhinestone or something, though. charm is small; under 2" long from wingtip to wingtip.  Heart section in middle is about 1/3" tall.  chain adjusts between 15-17" long.  please look at pics for better idea of size and style.
