Help With Hallmark and Value

I have had this bracelet for many years. I am assuming my mother purchased it in the early ‘70’s. Would appreciate help with the hallmark and an approximate value. Thank you.

It could be Alex Becenti, but he uses a stamp. I haven’t seen one engraved before.

Found a hallmark attributed to a Rose and Alvin Boy. This is a link to another piece attributed to them, I am not familiar with this hallmark, but looks like a good place to start your research. This style of bracelet with the heavy wires and real turquoise you see go around $220, they can be much more if done by an artist like Orville Tsinnie, or the stones being something special. Thanks for sharing.

Thank you both! I appreciate the information and will continue looking. This is a great start!
