Old women's/girl's bracelet.

I found this behind a floor length mirror in the foyer of an old (1886) house my daughter just bought.  We had to move this piece of furniture/mirror to clean and paint behind and this bracelet was just covered in what looked like 100 years of dirt!  It is 7" long and has a unique clasp that actually screws together. I've discovered that this is called a barrel clasp.  I was able to find what looks like an exact replica made by beadalon.  Everything else looks like silver and mother of pearl.  I thought the lighter pieces were made of mother of pearl but I've seen other similar ones that were carved of ivory.  I don't think it's made of ivory as it has a sheen that reflects in the light.  I'm no expert so if you have any questions please ask.  Thanks, Dave
