Unset Hand-carved Shell Cameo Antique

ntique hand carved Italian Cameo. It was once set in a gold bezel, but the previous owner sold the setting for melt. It has no setting.
This is a fine late 1800's piece of a lovely Victorian figure with great detail to the hair. Nice big Roman nose.
It measures 1/2" x 3/4". It weighs 1.5 grams. Not signed. The hairline on the back is not a crack that moves and appears to be a striation in the shell.
It has not been cleaned and is a little dirty.
