Hi Sarah.
Your mark is shown in Dorothy Rainwater's book "American Jewelry Manufactures".
It says S. Korff & Son was listed in the Jeweler's Circular - Keystone 1943-1965.
Also listed in the Jeweler's Buyers Guide in 1959.
Book says their advertising mentions diamond jewelry, rings, pins, bracelets, earrings and watch bands.
That's all the information I have on the company.
Pat.
