Searching for info on "sterling ->M-H<-"

[charlie25]

I dont have any background info on this cause my Mom found it at a yard sale. I have been looking for about a week now, on my own, but am having no luck at all. This ring is a man's ring with a turquois stone. The stone is open on the back so you can see the flat side. The sides of the ring are textured, wide at the top and narrows toward the bottom. THANKS so much for any info you can provide!
Charlie
