Steven buys his jewelry from markets and shops as he travels, and, he has a great deal given to him. Most of his beads are specialist, and are expensive. He is a connoisseur and very selective in what he wears. If you want to find items like his go to http://dharmashop.com/display.mgi?CAT=be&T=Beads - you will see one or two pieces almost identical.
I think these beads should be carried discretely and not worn as cheap jewelry. Steven often looks like a little kid playing at dressing up, he would be much better to follow Richard Gere's example - sheer class, not cheap bling!
