Vintage Krementz Rose Two Tone Gold Brooch

Sweet vintage Krementz rose figural brooch in yellow and rose gold. Beautiful three-dimensional rose with a delicate and lovely look, attached to the bar pin. It's marked on the pinstem Krementz with something after that I can't make out -- I suspect it's either a 10k or 925 mark because the pin looks like it could be either ten karat or gold over sterling. Lovely vintage condition with no issues, measuring 1 1/2" x 1/4".
