This is a Really Lovely Old Pin by the New England Glass Works with Cobalt Blue Enamel Leaves and Raised Flowers with Rhinestones and Blue Cabochon Centers in Silvertone, I believe Pot Metal.
The Brooch is 3" across and 1 1/2" and makes a Large Presentation. The Metal has a Nice Patina, some of the clear rhinestones have yellowed slightly, otherwise Great Condition. It is Marked with the NE in the Chalice.
