Antique Wax Seal Stamp Pendant in Green Glass Heraldic Heraldry Family Crest Coat of Arms

This is a wonderful glass wax seal stamp from the 1800s. The glass is a lovely yellowish green and has a chip in one corner which doesn't detract from the wax stamp impression. The impression is of heraldic content with a shield and figures standing on either side of the shield. A wreath and crown? are above the shield. I don't have wax so I can't do an impression to make the scene easier to see. The seal could be worn as a pendant as it has a loop at the top. The metal is bronze. It doesn't have a date or makers mark.
