Copper Turquoise Cuff Bracelet Stamped Copper Vintage

I Think This Is Wm Copper From What I Can Glean In My Search, But If You're Looking At This You Know More Than I Do. Please Zoom In And See What You Think. Good Condition For Age. Zoom In On The Pictures You Can See. There's A Bit Of Pitting On The Backside Of The Bracelet And Perhaps It Could Use A Good Cleanup. But Stones Are All Intact. Happy To Answer Any Questions You Might Have
