Gunner or Grimminger
by: Anonymous

Hi Josh

G in a SIX pointed star was used by:

Jakob Grimminger (mainly on Silver, Schwabisch Gmund, Germany ca. 1893 -1950s.

Examine the mark under a jewelers loupe or strong magnifying glass in good light and work out if it is a Five or Six pointed star.

Albert Gunner MFG Co. is a G in a five pointed star. I can't see the star from here, but the ring being 10K - I'm leaning towards Gunner.


Vintage Jewelry Hallmarks | G IN A STAR
by: Anonymous

Hi Josh thanks for writing in. What a lovely classic ring, the ruby looks free of any surface grazes or marks, it looks like this ring has been well cared for and ruby being high on the Mohs scale of Hardness helps. This jewelry mark would fall under vintage jewelry hallmarks and is the mark of:

Albert Gunner Mfg Co. Silversmiths, Attleboro, MA, USA - ca 1920 -1980s.

10K, 10ct or 416 parts per 1000, 41.6% gold. 10K is the Minimum USA gold standard. It is hard wearing.

best wishes,
Yvonne Hammouda-Eyre
