Labradorite beads were named after the location where founded, the Labrador Region of Canada. Labradorite beads are known for shiller or labradorescense in vivid metallic tints of blue, green and yellow. Labradorite body color is dark grey, grey-black, greenish-grey, colorless and brownish with a transparent to opaque quality.
