Hi Jon,
Just some observations and feelings. The filigree
work is beautiful and pretty much characteristic of the
area in which it was found. Since it is hinged, it probably contained something such as a piece of sponge or cloth, or some aromatic substance. I think it was/is a vinaigrette. Pieces of sponge or cloth were inserted into them then vinegar or perfume was dripped on the the sponge or cloth and the object was used to
ward of everything from cholera to foul odors. If I
had to date it, I would say somewhere between 500 and 1200 A.D.
You indicated that it is 23K gold. Whey does it appear white/silver in color or is the color balance of your photos off? What is the size of it? It certainly is a fascinating piece.
