This is a really amazing necklace from hot designer Joseph Brooks!  We love the stone that is used in the necklace - it is a clear QUARTZ crystal with black veins going through it to give it depth.  Check out the different sizes of the round beads, they vary between 1/4" to 3/5".   Each of the beads have been brilliantly cut to catch the light. The 40" long necklace looks amazing when worn long, or you can double it up for a variety of looks!
