Dugan produced this beautiful, green, opalescent art glass bowl circa 1905 and the pattern is known as Jeweled Heart. It's a wonderful piece with a folded bowl shape and a crimped rim. It is signed on the base with a D in a diamond mark.
The dish measures 7" long, 5" wide and 4" in height.
In excellent condition it has no chips, nicks or cracks at all.
