1910's Neo-Russian Two-Piece Solid "72" (18K) Brooch/Pendant W/1.20ctw Mine-Cut Diamonds & Green Guilloche Enamel in Original Leather Box - This piece is made of solid "72" (The Russian standard for 18k Gold), and boasts approximately 1.20ctw genuine SI1-SI2/G-H mine-cut diamonds. This piece was made during a very special time in Russia known as the "Neo Russian Modern" style. Most of these pieces were lost in the revolution, and are incredibly hard to find. This rare piece has a "detachable" front piece that is embelished with vibrant, forest green guilloche enamel. This piece can be worn as a pendant, or a brooch. You will never see another piece like this. There are slight signs of age, with slight faintness on the enamel. The piece comes in its original leather box, and measures: 1" x 7/8", and Weighs: 6.6 Grams. This is truly an investment quality, fine Russian antique, and we have never seen a piece quite like this one.
