I use a lot of these Wedding Beads for creating artful brooches along with my lampwork beads. I found this information below as well as this photo on: http://www.africantradebeads.com/Product_Index/Czech/Cz-Wedding/cz-wedding.html
"Colourful mixed collections of 1920's onwards, Czech produced ( Buksameh ) "Wedding beads" ... it is said that prison labour was used in their manufacture. Found in Mali where they are worn on ceremonial occasions by the Fulani and Peul people to this day. Included in the strands are the "light-bulb", "claw" "teardrop", triangular and "bottle" shapes. All the beads are in beautiful condition"
