Highly polished cut steel beads
Blue and white cameos of Wedgwood jasper.
Industrialist Matthew Boulton (1728–1809) of Birmingham, specializing in cut steel articles, is known for collaborating with Josiah Wedgwood (1730–1795) in combining jasper cameos and steel frames to make buttons, watch gussets and châtelaunes. It is likely that this box comes from the Boulton factory.
This box is also mounted in gold.
