These diamond-shaped amber beads are over 100 years old and are found in Mauritania and Niger. They are an imitation (like Bakelite or Parkesine) amber made in Germany from plant resin. Hole is approximately 1.5-2mm and has a decorative hole through the center, adding to design possibilities. Beads vary in size (see photo – SOLD SEPARATELY, not in a group) ; approximately 13mmx 19mm to 20mm x 27mm. Picked randomly, unless otherwise noted when ordering.
