Large vintage pastel colour gemstone cabochon floral spray bouquet brooch, delicate gold tone settings, raw ruby, emerald, sapphire

Large vintage natural gemstone cabochon encrusted, gold tone flower and leaf brooch. There are pink, blue and green gemstone cabochons carefully claw / prong set in the delicate gold tone settings. The leaves are beautifully formed in the gold coloured metal. The design is opulent and fabulous. I believe the cabochons are raw untreated rubies, emeralds and sapphires, but this is not my area of expertise! The striations within the natural stones are visible in the close-up pictures. It is possible the metal is unmarked gold, but the piece is not signed or stamped unfortunately. The orientation of the pin means that it could be worn as a statement pendant if a necklace chain is passed through the secured pin. The brooch is in very good vintage condition.
