It is clearly signed Steuben etched in the bottom of the bowl. Please see all 12 photos here for best description. So many different crystal and glass makers with sparkle or shimmer are nice, but makers like Steuben and Daum with their thickness and silky feel to the touch prismatic glass and crystal pieces are my favorite! This gorgeous bowl would be a showpiece no matter where you display it.
