Vintage solid 925 sterling silver handmade brutalist abstract walnut? dome ring

Vintage solid 925 sterling silver handmade brutalist abstract walnut? dome ring This is a vintage handmade ring with a very unique look. It is a brutalist free form design in a dome raised design. To me it looks like a walnut or tree branch with three decorative dashes across the front. Opposite lines in the sides. Stamped "STERLING" inside the band. Tested as sterling. Slightly out of the round as seen in photos. Hollow inside. About a size 6. Deep, warm patina from age. RARE! Tiffany & Co. Brighton Zales Kay Jewelers Jarod Shane Co.
