DAWG is Beasty Bling's jewelry line for men and dogs. All jewelry for pets and people are hand assembled couture and feature Beasty Bling's signature toggle which in this case is contemporary glass bead.  The flat beads are bakelite (a type of plastic that started being used in jewelry in the 1920s) and the round colorful beads are agate.  There are marbles made of agate called "aggies" and you can see the similarity.  The necklace measures 21 1/2".
