Barafa, which means circle fence, is a length of coiled vine with very small soela white shell rings bound along its length. This form of shell currency is extremely labour intensive since the hand ground rings are so tiny - rings to the cm ( to the inch) and each must be pierced, drilled and attached to the vine stem by hand. Traditionally, barafa is said to be stipulated for the final payment that pays off the debt.
Barafa us usually coiled and tied to be worn around the neck. This coil of four and a half circles is approximately 360 cm / 142 inches long and contains 8 shell rings to the cm / 16 shell rings to the inch, more than 2,000 shell rings in all.
