Comet color Potomac Pearls are handcrafted. Glass artisans dip perfectly round 4mm glass beads through dozens of different thin layers of pearl coating. Each layer must dry before coating the next. These layers bond and strengthen a beautiful and durable pearl pearl finish. Potomac Pearls are coated many times more than the cheap pearls that chip. The quality of Potomac Pearls exceeds even Czech Pearl standards, and competes with Swarovski's 5810 round pearls for shine and quality. Enjoy using these premium pearls in your stringing, beadweaving, knotting, wedding, earring, pendant, and other designs! receive a 16" (40cm) strand with 100 pearls in each pack.
