Very good work on the Verlys attribution, but might note that Verlys of America pieces were made at the Holophane Glass Co. in Newark, Ohio. My employer, Fenton Art Glass, bought this and other Verlys of America moulds in the mid-1960s. We've made this Vessel of Gems vase in a variety of colors, and I think it looks best in transparent or opalescent glass rather than opaque. Incidentally, some folks like to call it the "golf ball" vase.
