Very rare graduated green turquoise heishi beads  are strung by Aimee into an eye catching necklace. The toggle clasp is hand made in a fired copper. I bought the unstrung beads from a very reliable source. The copper toggle is also from another beading source. The green turquoise Is also referred to as gaspeite. This is a darker, untouched shade of the mineral. Its iron ore content causes the color. Both regular turquoise and gaspeite turquoise are derivatives of Calcite. Turquoise has more copper, Calcite more iron. The necklace is 23 inches. One of a kind.
