What is the item?

18k diamond bracelet with 1.80ct of diamonds in an Art Deco style.

Can you please provide all background information?

Bought from an antique dealer who had very little background regarding its age.

What are the markings?

18k, D180, 750 and others that are obliterated. The maker's mark appears to be a J and a B in capital letters, inside two circles (imagine a pair of spectacles).


Where are the markings?

The maker's mark is on the tongue of the clasp and the others are on the receiving clasp.
