#Russian gold #Art #Deco #brooch, beginning of the XX century. In the center there is an excellent #emerald - #cabochon with rich green color, size 5,9x4,8 mm. Along the edges of the main stone there are four old-cut #diamonds. Brooch has a diameter of 2.5 centimeters. Stamped 56 (56 gold purity was common standard in Russia before 1917), and a maker’s mark that I couldn’t identify. Brooch small, but quite massive - 11.7 gr.
