Renaissance Revival sword jabot-brooch. An exceptional and very rare jabot type brooch, created in England during the Victorian era, back in the 1880. This piece is fantastic and has been crafted with renaissance revival patterns in the shape of a miniature sword with jewels, in solid yellow gold of 18 karats with accents in carved platinum. The sword is well proportionate and made with gorgeous details. It is completely decorated with twisted woven wires, engravings and chiseled designs. The sword sheath, the grip pommel and the rain-guard are embellished with a fantastic assortment of eleven natural earth mined gemstones; such white colorless diamonds and vivid green demantoids garnets.
