What affects the value of Catamore Cameo Brooch?

• Condition of the mother of pearl carving, specifically looking for any chips, cracks, or yellowing of the silhouette.
• The integrity of the 12K gold-filled frame, as heavy wear or brassing to the metal can decrease the $50-$70 market value.
• Clarity and contrast of the cameo subject against the black onyx background.
• Presence of original designer packaging or provenance from the mid-20th century.

How to Identify Catamore Cameo Brooch?

• Look for the 'CATAMORE' or 'CATAMORE 1/20 12K G.F.' hallmark stamped on the reverse of the metal frame.
• Verify the materials consist of a carved mother of pearl silhouette layered over a genuine black onyx base rather than molded plastic.
• Examine the setting for a secure rolling C-clasp or safety pin closure typical of the 1940-1960 era.
• Check for the characteristic 12K gold-filled finish which maintains a richer luster than standard gold plating.
