Scoop Shaped Bowl Purple Burgandy Enamel over Aluminum Celtic Swirl Exquisite

I believe this to be vintage but unfortunately could not read half of the stamp on felt on the bottom so could not properly research it. I do know it's lovely and very unique. Very glossy enamel on metal, I believe it's aluminum but might be stainless steel. It's glossy but does have some light scratches in the polished metal. Neat raised swirl pattern reminds me of celtic rune designs I've seen. Measures about 6" diameter and about 3" high.
