I have put all my antique beads, some from the 18th Century - the hand painted Venetian trade beads- - and strung them with Howlite beads from China.  Happy with the results. If you want the necklace but want an easier clasp, I can restring to your specifications. Beads are from Africa, Italy and Afghanistan. A few of the older beads may be worth more than the entire neckkace!necklace! Three strands. 24 inches a strand.
