La Lechuga
La Lechuga (English: ''The Lettuce'') is a monstrance made between 1700 and 1707 by José de Galaz for the of Bogotá, then part of the New Kingdom of Granada. It was paid for by a group of Jesuits, probably in order to hide the gems contained in it from the Spanish Crown. Currently, La Lechuga is owned by the Bank of the Republic and is on permanent display at the Miguel Urrutia Art Museum in Bogotá, Colombia. History It is widely believed that a group of Jesuits ordered La Lechuga to be produced in order to hide the gemstones contained in it from Spanish Crown. The Jesuits contracted the Spaniard José de Galaz whomade the monstrance, with the help of two other goldsmiths, between 1700 and 1707 for a fee of $1,100 Reales (equivalent to $100,000 USD in 1996). When José de Galaz finished making La Lechuga on 16 July 1707, he estimated it to be worth $20,000 Reales, or $2,000,000 USD in 1996. The name comes from the large number of emeralds built into the monstrance, which make ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baroque Pearl
Baroque pearls are pearls with an irregular, non-spherical shape. Shapes can range from minor aberrations to distinctly ovoid, curved, pinched, or lumpy shapes. Most cultured freshwater pearls are baroque because freshwater pearls are mantle-tissue nucleated instead of bead nucleated. Cultured saltwater pearls can also be baroque, but tend to be more teardrop-shaped due to the use of a spherical, nucleation bead. The most valuable baroque pearls are the South Sea and the Tahitian pearls, which are produced by ''Pinctada margaritifera'' (black-lipped oyster Oyster is the common name for a number of different families of salt-water bivalve molluscs that live in marine or brackish habitats. In some species, the valves are highly calcified, and many are somewhat irregular in shape. Many, but not ...s) and ''Pinctada maxima'' (gold-lipped and white-lipped oysters).

India
India, officially the Republic of India (Hindi: ), is a country in South Asia. It is the seventh-largest country by area, the second-most populous country, and the most populous democracy in the world.

Amethysts
Amethyst is a violet variety of quartz. The name comes from the Koine Greek αμέθυστος ''amethystos'' from α- ''a-'', "not" and μεθύσκω (Ancient Greek) / μεθώ (Modern Greek), "intoxicate", a reference to the belief that the stone protected its owner from drunkenness. Ancient Greeks wore amethyst and carved drinking vessels from it in the belief that it would prevent intoxication. Amethyst, a semiprecious stone, is often used in jewelry and is the traditional birthstone for February. Structure Amethyst is a purple variety of quartz (SiO2) and owes its violet color to irradiation, impurities of iron and in some cases other transition metals, and the presence of other trace elements, which result in complex crystal lattice substitutions.Michael O'Donoghue (2006), ''Gems'', Butterworth-Heinemann, 6th ed. The hardness of the mineral is the same as quartz, thus making it suitable for use in jewelry. Hue and tone Amethyst occurs in primary hues from a l ...

Emeralds
Emerald is a gemstone and a variety of the mineral beryl (Be3Al2(SiO3)6) colored green by trace amounts of chromium or sometimes vanadium.Hurlbut, Cornelius S. Jr. and Kammerling, Robert C. (1991) ''Gemology'', John Wiley & Sons, New York, p. 203, . 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. Etymology The word "emerald" is derived (via fro, esmeraude and enm, emeraude), from Vulgar Latin: ''esmaralda''/''esmaraldus'', a variant of Latin ''smaragdus'', which was a via grc, σμάραγδος (smáragdos; "green gem") from a Semitic language. According to Webster's Dictionary the term emerald was first used in the 14th century. Properties determining value Emeralds, like all colored gemstones, are graded using four basic parameters–the four ''C''s of connoisseurship: ''color'', ''clarity,'' ''cut'' and ''carat weight''.

Spanish Colonization Of The Americas
Spain began colonizing the Americas under the Crown of Castile and was spearheaded by the Spanish . The Americas were invaded and incorporated into the Spanish Empire, with the exception of Brazil, British America, and some small regions of South America and the Caribbean. The crown created civil and religious structures to administer the vast territory. The main motivations for colonial expansion were profit through resource extraction and the spread of Catholicism by converting indigenous peoples. Beginning with Columbus's first voyage to the Caribbean and gaining control over more territory for over three centuries, the Spanish Empire would expand across the Caribbean Islands, half of South America, most of Central America and much of North America. It is estimated that during the colonial period (1492–1832), a total of 1.86 million Spaniards settled in the Americas, and a further 3.5 million immigrated during the post-colonial era (1850–1950); the esti ...

Baroque Sculpture
Baroque sculpture is the sculpture associated with the Baroque style of the period between the early 17th and mid 18th centuries. In Baroque sculpture, groups of figures assumed new importance, and there was a dynamic movement and energy of human forms—they spiralled around an empty central vortex, or reached outwards into the surrounding space. Baroque sculpture often had multiple ideal viewing angles, and reflected a general continuation of the Renaissance move away from the relief to sculpture created in the round, and designed to be placed in the middle of a large space—elaborate fountains such as Gian Lorenzo Bernini‘s Fontana dei Quattro Fiumi (Rome, 1651), or those in the Gardens of Versailles were a Baroque speciality. The Baroque style was perfectly suited to sculpture, with Bernini the dominating figure of the age in works such as ''The Ecstasy of St Theresa'' (1647–1652). Much Baroque sculpture added extra-sculptural elements, for example, concealed lighting, or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bas-relief
Relief is a sculptural method in which the sculpted pieces are bonded to a solid background of the same material. The term ''relief'' is from the Latin verb ''relevo'', to raise. To create a sculpture in relief is to give the impression that the sculpted material has been raised above the background plane. When a relief is carved into a flat surface of stone (relief sculpture) or wood (relief carving), the field is actually lowered, leaving the unsculpted areas seeming higher. The approach requires a lot of chiselling away of the background, which takes a long time. On the other hand, a relief saves forming the rear of a subject, and is less fragile and more securely fixed than a sculpture in the round, especially one of a standing figure where the ankles are a potential weak point, particularly in stone. In other materials such as metal, clay, plaster stucco, ceramics or papier-mâché the form can be simply added to or raised up from the background. Monumental bronze reliefs ...

Yellow Sapphire
Sapphire is a precious gemstone, a variety of the mineral corundum, consisting of aluminium oxide () with trace amounts of elements such as iron, titanium, chromium, vanadium, or magnesium. The name sapphire is derived via the Latin "sapphirus" from the Greek "sappheiros", which referred to lapis lazuli. It is typically blue, but natural "fancy" sapphires also occur in yellow, purple, orange, and green colors; "parti sapphires" show two or more colors. Red corundum stones also occur, but are called rubies rather than sapphires. Pink-colored corundum may be classified either as ruby or sapphire depending on locale. Commonly, natural sapphires are cut and polished into gemstones and worn in jewelry. They also may be created synthetically in laboratories for industrial or decorative purposes in large boule (crystal), crystal boules. Because of the remarkable hardness of sapphires 9 on the Mohs scale of mineral hardness, Mohs scale (the third hardest mineral, after diamond at 10 ...
