Silvered bronze, size 9 ¼ with 3.7mm band decorated in alternate spiral and dot motif. That form is specifically identified with the Fishpool Hoard dated 1400-60. This example is surmounted by a diamond, perhaps to accommodate resizing. That configuration is more commonly seen with a heart and dated to the Tudor period (1485-1603).  Professionally refurbished with the silver overlay restored. Jewelry gift boxed with certificate of authenticity.
