In good condition. The mounting with gentle surface wear. Discoloration to the tops of the ring's shoulders, but this is seen only on close inspection and speaks to the age of the piece. Porosity to the shank seen under 10x magnification. The cameo remains in good condition with no apparent chips or abrasions; the very dark brown base is semi-opaque. Signed on the white chalcedony, beneath the bust.

Salvator Passamonti (1757-1822) was a student of the famed sculptor Canova and became a noted Italian medalist who for a period of time held a post of chief engraver at the Mint of Rome. At the Great Exhibition in London in 1851, Passamonti exhibited an onyx cameo of Jupiter defeating the Titans which is credited as one of his finest productions, and his signature appears on the Annual Medal of 1851 of Pope Pius VII.
