Sheffiled was produced beginning in 1936 and continued through 1938. It was predominately made in crystal and crystal satin, but Ruby can also be found, along with two different shades of blue. The etchings Halo and Silvertone can also be found on Sheffield items.
The item pictured is the 'regular' vase, which has been cupped inward so that it measures 5 3/4" tall.
