Dogtooth beads are characterized by a black core encircled by ruffled white stripe. Each extra long strand of matching vintage beads measures approximately 38" in length with individual beads 6-10mm wide by 8-10mm in diameter. Beads have been nicely arranged in a graduated pattern with the largest in the center of the strand. Add this strand to your collection today!
