Ceramic Cast Vase Art Nouveau style Pitcher, Dark Moody Witchy Gothic Home Decor

Elegant Ceramic red clay vase with pewter gray color surface finish. Looks and almost sounds like metal when tapped. A test bottom scratch exposed a hard pinkish red clay. There is a barely visible hallmark in a triangle shape, but unreadable. An Art Nouveau style, its vintage, but likely not antique (best guess) 12.5 inches tall. Good vintage condition. Loves peacock feathers and pink roses....
