No hallmarks but has been tested.

The front of the case has the most stunning embossed floral detail, wonderful silversmithing.

The back of the locket case is plain silver.

Typical chunky Victorian bail, allowing for wear on a thicker chain if desired.  

The interior is framed and glazed to right side of case.

Closes with a resounding click.

Measurements: 2.25" (from top of bail) by 1.25".

Weight: 15.24gms.

In good antique condition, some dings to back of case, commensurate with age and use.
