Well these are old - they have been laying in my bin for many years - I thought originally they were snake but I believe they are shark. There is one old sand cast trade bead.
The reds are glass trade venetian. They vary in color and size.
There are 2 striped I think they are some kind of nut beads. Have never actually been able to ID them.
Lastly there are 3 oblong carved beads - they measure about 1 inch each. No uniform coloration to each.
The entire piece measures 30 inches so just slips over the head. I acquired this set from a bead trader over 30 years ago at the Tucson Gem Show.
Not sure if this helps but they weigh 79.4 grams
I hate to list things that I am not 100% sure of the origin so this set has just sat around for years. Any further info that you would like to pass onto me I'd be happy to know. Don't be shy about sharing.
