This necklace is made of sterling silver, and has alternating canary yellow and white princess cut  CZs which are graduated which means that the stones are largest in front and gradually get smaller.  It is 16-1/2 inches in length and has a tab insert clasp with a safety latch.  The CZs are clear and brilliant, however, they are so reflective they appear to be cloudy in the photo.  Please keep that in mind.
