Because these are handmade, no two beads are alike. Some are smoother, larger, smaller, some have a jingle sound to them.
The African bicone beads measure in the range of 6.5mm to 8mm. Each strand has 40 to 42 beads.
These beads are mostly copper, but there will be traces of various other metals. The metal refining process in Africa isn't the purest so there will always be some other trace metals as part of the mix.
