By the way the tines are welded on the back, I’d place this silver beauty in France, c. 1850. The first layer of this tiara comb is an intricate rectangular silver design, on top of which is a smaller strip with a larger pattern. Three medalions are welded to the strip in the front so they can hold the arched tiara bridge, punctuated by roses and silver buttons.
I think this is a one-of-a-kind original piece, which shows the thought of the craftsman at a time when many combs remained unsigned. Because there are no pearls or other jewels, it was not made for an aristocrat, but I can imagine it enhanced the beauty of any woman lucky enough to have worn it.
