This lovely piece by Ariana Boussard-Reifel is available in sterling silver (as shown) and in brass.
The site explains, “Sculptural and bold, the Teton cuff is for the Wonder Women of our times. This cuff sits balanced and close to the skin, our customers rave about how comfortable it is to wear. Inspired by the Rocky Mountains where Ariana was raised, this cuff is undeniably powerful. Measures 6.75″ interior circ. including 1″ opening.”
The silver bracelet is available for USD$1,695. The brass is priced at $845.
Looks like Robert Lee Morris. Maybe she was a apprentis of his.
It does remind me of some of his work, now that you mention it!
