The French put many dressings on these large brass tiara combs. I have one with opals. Sometimes the tines are bent so the top can be worn as a tiara. Other times, the comb is in its original formation.
This one, c. 1830, has French import marks and two rows of citrines in graduating sizes. The stones are clean, translucent, and well matched in color. The first row of stones is supported by a bridge of brass leaves separated by balls, which attaches to the comb with a floral applique. Its estimated worth is between 3000 and 4000 GBP.
