Quantity of original 19th century jet sections which look to have been set up in 2 bracelets at one time or even possibly as a large colar with a central large section?

From an old estate and all original, the 11 carved sqares are all carved to take 2 cords behind and are all good, they match the large oval section, the other items all came from the same estate but seem to be a different material, I have included because they may be of some use to a buyer, one is actually a small watch fob.

Sold as a set of very nice "beads" and for restoration now.

Size: approx 4.5 cm long x 3.7 cm across the largest section.

Please look at the images closely as they represent an important part of the description, thanks.

Any questions please ask.
