Turquoise ring Size 7 Sterling Halo

Turquoise and Sterling silver halo / crown ring 925 stamp to prove true sterling But the weird part is it does look gold (or tarnished) on the actual band. I would’ve thought it was not sterling because it’s almost like the silver tone has rubbed off ! Size 7 (Sits on my ring finger which typically wears a 6.5. This ring probably could range anywhere from 6.25 to 7.) Oval shaped teal turquoise stone in the center. Surrounded by a crown/full halo of bumpy beaded sterling silver droplets.
