Material Notes
The cameo appears to be carved shell, almost certainly helmet shell (Cassis) rather than stone.
Evidence:
Warm cream figure against a peach-orange background
Slight translucency
Soft, flowing hair carving rather than sharply undercut lines
Style & Carving
Classical female profile facing right
Hair swept up with loose curls — a Neoclassical Revival motif
Smooth modeling of neck and shoulders
Not a generic “cookie-cutter” cameo: the hair has depth and individuality
This level of carving suggests mid- to higher-quality workshop production, likely Italian (Naples/Torre del Greco), which dominated shell cameo carving in the 19th century.
Mount & Construction
Metal
The mount is gilt brass or pinchbeck, not solid gold.
Rich yellow tone with engraved decoration on the reverse.
This was very typical for Victorian cameo jewelry intended to look luxurious without the cost of gold.
Design
The brooch is horizontally oriented with:
Central oval cameo
Symmetrical fan-shaped side panels
Openwork filigree design
This winged / fan form is distinctly Victorian and was fashionable from the 1860s through the 1880s.
Pearls
The pearls appear to be seed pearls, most likely natural.
They are:
Small
Slightly irregular
Set individually (not molded)
Seed pearls were extremely popular in Victorian jewelry and often symbolized:
Purity
Mourning (in some contexts)
Refinement
This piece is not strict mourning jewelry, but the pearls do nod toward sentimental Victorian symbolism.
Back & Findings (Dating Clues)
From the rear image:
Tube hinge (long barrel hinge) → pre-1900
C-clasp (no safety catch) → strongly Victorian
Decorative engraving on the back → quality-conscious production
