I ran across this by accident, i believe you will find the ring is modern. For one thing incised marks didn't generally appear until the later 19th c. and besides I have had essentially the same ring. I wonder if the SAG mark isn't STG. I don't believe any early ring would have that ridge running down the middle of the inside. Finally early claddagh rings are extremely rare, and a google image search will find you quite a few examples of yours, or close to it.
Sorry, but good hunting
