Renaissance Revival 1880 Sword Jabot In 18Kt Gold With Demantoids And Diamonds
Located in Miami, FL
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. It is fitted with a sheath to slide the blade very tight, which is attached to a decorative security chain. This magnificent piece should be an important addition to any serious jewelry collection and will be a great conversation piece when you display it with your dress or on the lapel of your jacket.
Demantoids
Demantoid is the green gemstone variety of the mineral andradite, a member of the garnet group of minerals. Andradite is a calcium- and iron-rich garnet. Ferric iron is the cause of the green in the stone. Although garnets have been known since ancient times, the demantoid variety was not discovered until 1868 in Russia's western central Ural Mountains. The find was an alluvial deposit about 110 km from Ekaterinburg, north by northwest along the Bobrovka River, near the village of Elizavetinskoye. Miners were immediately stunned by the highly refractive nature of the gem material, which is atypical for garnet. They began comparing it to diamond and referred to it as "demantoid", from the old German Demant, meaning diamond. The reason is obvious, with its high brilliance and dispersion. However, as demantoid garnets are quite rare and found in so few locations, they can command quite high prices, especially if they have a particularly lovely horsetail inclusion. Most stones are less than one carat in size after cutting in polishing. Demantoid gems...
