Help idenify scandinavian makers mark on Choker?

[rob h]

I am guessing this is a scandinavian choker/necklace. It looks like the mark is an H with a period in a circle with the word sterling above it.There is a norweigan makers mark with an H, but not a period after the H. He is Ivar T. Holth.

Your mark looks like this one which is on the USPTO Site:

HANNELORE GABRIEL, DOING BUSINESS AS H. GABRIEL & CO., GOLDSMITHS 1469 ROSENA AVE. MADISON, OHIO 44057 MADISON OHIO 44057. FIRST USE IN COMMERCE: 1975
