A spectacular Christmas Tree pin brooch, an  unsigned beauty, based on my research made out of Czech glass prong set in base metal, unfinished back, open back stone setting, vintage, it would make a great addition to any jewelry collection! Condition: pre-owned vintage condition, the reverse has unfinished metal as seen in the photos, one stone has a tiny chip in the corner, from a non-smoking environment.
