I bought these strands in 2011 in Ghana. The inner strand is from Florence Arare, KT Beads, Agomanya (near Accra):beads from this strand are about 24-25 mm large. I bough the outer strand, which is more coarsely made, in a market in Kumasi. "Beads of beads" were commonly made with cheap chinese seed beads; those made with old Venetian beads like these were sold at 1.5-2 $ each. I presumed they were quite recently made, as I've never seen them before in previous years in Florence factory or in Koforidoua bead market.
