Antique Gold Wedding Ring

by Lucy

I have an antique wedding ring from my grandmother that dates from 1898 to 1905 period. It is a gold and platinum ring with six prong tiffany diamond solitare setting. The back of ring has a gap. The only marking is the word "Hallmark" with an underline from the lower right side of H to the left side of K.

I know there was a antique watchmaker that had this name. Otherwise trying to search a hallmark called hallmark has proven beyond my ability.




The ring would have been most likely purchased in Minnesota, USA or Ontario, Canada.

Any clues to the rings origin would be most appreciated.
