J.B
- Recorded on
- 2 pieces
The initials "J.B" represent a two-letter maker or sponsor stamp found across distinct silvermaking traditions. Because plain block or serif initials were widely used, identifying the specific workshop or artisan depends on the accompanying purity, origin, and assay marks struck alongside the letters.
On Irish sterling silver, such as traditional Claddagh jewelry, "J.B" functions as a maker's or sponsor's mark entered with the Dublin Assay Office. On these pieces, the initials appear alongside full Irish statutory hallmarks, typically including the Dublin city mark, the 925 fineness stamp, and occasionally a "MADE IN IRELAND" origin mark.
When struck alone with only a standard "STERLING" stamp and no European assay marks, "J.B" indicates an independent artisan, such as an unidentified Southwestern or American studio silversmith. Collectors holding a piece with this mark should check the rest of the band or reverse to see whether it carries formal national assay symbols or simple trade purity stamps.
