Need Help with Brutalist?? Ring

[trdhrdr007]

Picked up some jewelry from one of my estate sale contacts yesterday. This ring was in the lot & I'm thinking it may be a brutalist piece. The marks are almost impossible to read. I believe the long indentation reads "sterling". The other mark is possibly "HAM". Help with the style, stone type, & value would be appreciated. I also picked up a vintage Mexico mixed metal biker ring which is only the 2nd one I've ever found.

Thats an odd pair.

Lapis or sodalite maybe on the stone. Brutalist looks about right too. That Mexican biker ring will do very well if it cleans up some.

Lore says that when they outlawed brass knuckles, they started making brass rings for their knuckles

Really interesting rings. Definitely a brutalist ring with lapis stone.
