These beads were also traded during the fur trade era. In the mid-1800’s they became known as Hudson Bay beads. They had two distinct colors of glass – one layered over the other. The outer layer was red and the inside layer was green, yellow, or white. The newer versions of the Hudson Bay beads are known as white hearts and have a white inner layer and a clear glass exterior from the range of the rainbow colors. Sizes and shapes vary. They are made today in France, Czech Republic, and India.
