Safed Chalwan is a kind of white translucent enamel used for encrusting gems and precious stones for making jewels.
This enamel is used at the reverse side of the jewels in order to contrast the color of the gems (usually ruby or jade) with a stark white background. [1]
In this technique of enameling, an opaque white outlined cartouche is fired and leveled with the stone to be embedded. On cooling down the enamel develops a hard coating around and the stone is set in it. [2]
Emerald is a gemstone and a variety of the mineral beryl (Be3Al2(SiO3)6) colored green by trace amounts of chromium and/or sometimes vanadium. Beryl has a hardness of 7.5–8 on the Mohs scale. Most emeralds are highly included, so their toughness (resistance to breakage) is classified as generally poor. Emerald is a cyclosilicate.
Jewellery or jewelry consists of decorative items worn for personal adornment, such as brooches, rings, necklaces, earrings, pendants, bracelets, and cufflinks. Jewellery may be attached to the body or the clothes. From a western perspective, the term is restricted to durable ornaments, excluding flowers for example. For many centuries metal such as gold often combined with gemstones, has been the normal material for jewellery, but other materials such as shells and other plant materials may be used.
The Koh-i-Noor, also spelt Kohinoor and Koh-i-Nur, is one of the largest cut diamonds in the world, weighing 105.6 carats (21.12 g). It is part of the British Crown Jewels.
The Hope Diamond is one of the most famous jewels in the world, with ownership records dating back almost four centuries. Its much-admired rare blue color is due to trace amounts of boron atoms. Weighing 45.52 carats, its exceptional size has revealed new findings about the formation of diamonds.
A necklace is an article of jewellery that is worn around the neck. Necklaces may have been one of the earliest types of adornment worn by humans. They often serve ceremonial, religious, magical, or funerary purposes and are also used as symbols of wealth and status, given that they are commonly made of precious metals and stones.
The Peacock Throne was a famous jewelled throne that was the seat of the emperors of the Mughal Empire in India. It was commissioned in the early 17th century by Emperor Shah Jahan and was located in the Diwan-i-Khas in the Red Fort of Delhi. It was named after a peacock as two peacocks are shown dancing at its rear.
Vitreous enamel, also called porcelain enamel, is a material made by fusing powdered glass to a substrate by firing, usually between 750 and 850 °C. The powder melts, flows, and then hardens to a smooth, durable vitreous coating. The word comes from the Latin vitreum, meaning "glass".
A brooch is a decorative jewelry item designed to be attached to garments, often to fasten them together. It is usually made of metal, often silver or gold or some other material. Brooches are frequently decorated with enamel or with gemstones and may be solely for ornament or serve a practical function as a clothes fastener. The earliest known brooches are from the Bronze Age. As fashions in brooches changed rather quickly, they are important chronological indicators. In archaeology, ancient European brooches are usually referred to by the Latin term fibula.
The Orlov, also known as The Great Mughal Diamond, is a large diamond of Indian origin, currently displayed as a part of the Diamond Fund collection of Moscow's Kremlin Armoury. It is described as having the shape and proportions of half a chicken's egg. In 1774, it was encrusted into the Imperial Sceptre of Russian Empress Catherine the Great.
Cloisonné is an ancient technique for decorating metalwork objects with colored material held in place or separated by metal strips or wire, normally of gold. In recent centuries, vitreous enamel has been used, but inlays of cut gemstones, glass and other materials were also used during older periods; indeed cloisonné enamel very probably began as an easier imitation of cloisonné work using gems. The resulting objects can also be called cloisonné. The decoration is formed by first adding compartments to the metal object by soldering or affixing silver or gold as wires or thin strips placed on their edges. These remain visible in the finished piece, separating the different compartments of the enamel or inlays, which are often of several colors. Cloisonné enamel objects are worked on with enamel powder made into a paste, which then needs to be fired in a kiln. If gemstones or colored glass are used, the pieces need to be cut or ground into the shape of each cloison.
The Imperial Crown of the Holy Roman Empire, a hoop crown with a characteristic octagonal shape, was the coronation crown of the Holy Roman Emperor, probably from the late 10th century until the dissolution of the Holy Roman Empire in 1806. The crown was used in the coronation of the King of the Romans, the title assumed by the Emperor-elect immediately after his election. It is now kept in the Imperial Treasury at the Hofburg in Vienna, Austria.
A treasure binding or jewelled bookbinding is a luxurious book cover using metalwork in gold or silver, jewels, or ivory, perhaps in addition to more usual bookbinding material for book-covers such as leather, velvet, or other cloth. The actual bookbinding technique is the same as for other medieval books, with the folios, normally of vellum, stitched together and bound to wooden cover boards. The metal furnishings of the treasure binding are then fixed, normally by tacks, onto these boards. Treasure bindings appear to have existed from at least Late Antiquity, though there are no surviving examples from so early, and Early Medieval examples are very rare. They were less used by the end of the Middle Ages, but a few continued to be produced in the West even up to the present day, and many more in areas where Eastern Orthodoxy predominated. The bindings were mainly used on grand illuminated manuscripts, especially gospel books designed for the altar and use in church services, rather than study in the library.
Navaratna is a Sanskrit compound word meaning "nine gems" or "ratnas". Jewellery created in this style has important cultural significance in many southern, and south-eastern Asian cultures as a symbol of wealth, status, and also as having other claimed talismanic benefits to health and wellbeing. The setting of the stones is believed to hold mystical powers, tied to astrology, mythology and intrinsically linked to the Indian religions of Hinduism, Jainism and Buddhism. The historic origin of the significance behind the nine gems has proved impossible to trace but is tied to mythological concepts around cosmology and astrology and the "Navagrahas", or "nine celestial gods".
The Green Vault is a museum located in Dresden, Germany, which contains the largest treasure collection in Europe. The museum was founded in 1723 by Augustus the Strong of Poland and Saxony, and it features a variety of exhibits in styles from Baroque to Classicism. The Green Vault is named after the formerly malachite green painted column bases and capitals of the initial rooms. It has some claim to be the oldest museum in the world; it is older than the British Museum, opened in 1759, but the Vatican Museums date their foundation to the public display of the newly excavated Laocoön group in 1506.
Hardstone carving is a general term in art history and archaeology for the artistic carving of predominantly semi-precious stones, such as jade, rock crystal, agate, onyx, jasper, serpentinite, or carnelian, and for an object made in this way. Normally the objects are small, and the category overlaps with both jewellery and sculpture. Hardstone carving is sometimes referred to by the Italian term pietre dure; however, pietra dura is the common term used for stone inlay work, which causes some confusion.
Kundan is a traditional form of Indian gemstone jewellery involving a gem set with a gold foil between the stones and its mount, usually for elaborate necklaces. The method is believed to have originated in the royal courts of Rajasthan and Gujarat. It is one of the older forms of jewellery made and worn in India. The word kundan means highly refined gold, and a highly refined and pure form of molten gold is used.
The Dunstable Swan Jewel is a gold and enamel brooch in the form of a swan made in England or France in about 1400 and now in the British Museum, where it is on display in Room 40. It was excavated in 1965 on the site of Dunstable Friary, and is presumed to have been intended as a livery badge given by an important figure to his supporters; the most likely candidate is probably the future Henry V of England, who was Prince of Wales from 1399.
The Middle Ages was a period that spanned approximately 1000 years and is normally restricted to Europe and the Byzantine Empire. The material remains we have from that time, including jewelry, can vary greatly depending on the place and time of their creation, especially as Christianity discouraged the burial of jewellery as grave goods, except for royalty and important clerics, who were often buried in their best clothes and wearing jewels. The main material used for jewellery design in antiquity and leading into the Middle Ages was gold. Many different techniques were used to create working surfaces and add decoration to those surfaces to produce the jewellery, including soldering, plating and gilding, repoussé, chasing, inlay, enamelling, filigree and granulation, stamping, striking and casting. Major stylistic phases include barbarian, Byzantine, Carolingian and Ottonian, Viking, and the Late Middle Ages, when Western European styles became relatively similar.
