This hallmark?
Can't help with the hallmark, but I have a couple of coomments re the stone.
You are living in a time when most stones are artifically improved: diamonds have their inclusions lasered out, stones are cooked to heighten their colour(almost all coloured stones of any value that can stand the heat), oiled to heighten or blend the colour(emeralds, rubies), coated with metallic fumes to give an iridescent appearance("mystic" and "pink" topaz), subjected to radiation (green diamonds so toxic they have to be kept in a safe lined with an inch of lead) etc etc. Then there are all manner of synthetic stones - synthetic spinel, synthetic corundum (sapphire, ruby) - and imitations (cubic zirconia) and "similants" (rutile as a diamond similant)
The ring you have looks to be older. From the picture one can't tell the colour. Since the ring is sterling the likelihood of the stone being ruby, sapphire etc is slim tho not out of the question - but most likely it is something like garnet (which is a very large family of gemstone ranging from colourless to yellow, orange, red, green and so densely red that it appears black).
It also is impossible to tell from a picture whether any stone is "real" - improved or not. Synthetic "rubies" (most often red-dyed spinel) etc were usually set in 10k. Garnet was so out of fashion that it was not even considered fit for "gold".
(One more thing about garnet, it is monochroic - ie one colour only, from whichever angle you look at it; ruby is dichroic, ruby red from the top and a watery pinkish colour from below)
