Lovely little brooch is Czech red glass set in brass with a few touches of copper. It measures 1 1/2" long by 1" wide. Very delicate and detailed workmanship. The red glass is in fine condition except for a teeny bump in the glass, just right of the glare from the lamp in the photo. You need a loupe to see it, barely evident by touch. Safety clasp works well. I wore it to work yesterday and received many compliments! No makers mark that I can see.
