Exquisitely Carved Pink Shell High Relief Cameo Brooch (A2656)

This is a magnificently carved cameo.
I do believe this is made from a Caribbean conch shell, as it is a very light pink color.
Highly detailed and in high relief.
The metal frame is not marked and does not test as sterling.
Possibly pewter or some type of base metal.
Its 1.75".
Absolutely stunning and unique piece

Please look at all the photos, as they are part of the description. I try my best to point out any flaws.
Also please remember this is a preloved piece and may show signs of light wear, marks, scratches, etc.
I will be posting a lot more jewelry, Keep checking back.
