13x4mm African Turquoise Tube Beads - 16 Inch Strand. Beautiful variegated green color.
African Turquoise is a form of spotted jasper, but it does not contain turquoise; the matrix (black lines) are similar to genuine turquoise matrix, which is why it is named so. Because it's jasper, it's harder than turquoise.
