Lodewyk Van Bercken
Lodewyk van Bercken (also known in French as ''Louis de Berquem'') was a mid- to late-15th century Flemish jeweller and diamond cutter, renowned in the industry for inventing the scaif. The device revolutionized the diamond cutting industry and contributed to increased popularity of diamonds. Van Bercken was born in Bruges. He is credited with inventing the scaif, a polishing wheel infused with a mixture of olive oil and diamond dust. With the scaif, it became possible to polish all the facets of the diamond symmetrically at angles that best reflected the light. Charles the Bold Charles the Bold, Duke of Burgundy became the patron of van Bercken and in the 1470s commissioned him to cut a 137 carat (27.4 g) stone that later became known as the Florentine Diamond. Van Bercken experimented with three diamonds belonging to Charles the Bold. One stone was the Beau Sancy, another became the property of Pope Sixtus V, and the third was given by Charles to Louis XI. Later Charles the ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Diamond Cuts
A diamond cut is a style or design guide used when shaping a diamond for polishing such as the brilliant cut. Cut does not refer to shape (pear, oval), but the symmetry, proportioning and polish of a diamond. The cut of a diamond greatly affects a diamond's brilliance; this means if it is cut poorly, it will be less luminous. In order to best use a diamond gemstone's material properties, a number of different diamond cuts have been developed. A diamond cut constitutes a more or less symmetrical arrangement of facets, which together modify the shape and appearance of a diamond crystal. Diamond cutters must consider several factors, such as the shape and size of the crystal, when choosing a cut. The practical history of diamond cuts can be traced back to the Middle Ages, while their theoretical basis was not developed until the turn of the 20th century. Design, creation and innovation continue to the present day: new technology—notably laser cutting and computer-aided design—ha ...

Year Of Death Unknown
A year or annus is the orbital period of a planetary body, for example, the Earth, moving in its orbit around the Sun. Due to the Earth's axial tilt, the course of a year sees the passing of the seasons, marked by change in weather, the hours of daylight, and, consequently, vegetation and soil fertility. In temperate and subpolar regions around the planet, four seasons are generally recognized: spring, summer, autumn and winter. In tropical and subtropical regions, several geographical sectors do not present defined seasons; but in the seasonal tropics, the annual wet and dry seasons are recognized and tracked. A calendar year is an approximation of the number of days of the Earth's orbital period, as counted in a given calendar. The Gregorian calendar, or modern calendar, presents its calendar year to be either a common year of 365 days or a leap year of 366 days, as do the Julian calendars. For the Gregorian calendar, the average length of the calendar year (the mea ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Sancy
The Sancy, a pale yellow diamond of , was once reputed to have belonged to the Mughals of antiquity, but it is more likely of Indian origin owing to its cut, which is unusual by Western standards. The stone has been owned by a number of important figures in European history, such as Charles the Bold, James VI and I, and the Astor family. The shield-shaped stone comprises two back-to-back crowns (the typical upper half of a stone) but lacks any semblance to a pavilion (the lower portion of a stone, below the girdle or midsection). History The diamond now known as the ''Sancy'' began as an even larger diamond called the ''Balle de Flandres'' with a possible weight of over . The ''Balle'' was part of the dowry of Valentina Visconti when she married Louis I, Duke of Orléans (the younger brother of King Charles VI of France) in 1398. While the precise path of ownership over the next 75 years is uncertain, the stone found its way to Charles the Bold, Duke of Burgundy, who lost it tog ...

Beau Sancy
The Beau Sancy is a 34.98-carat diamond originally mined in India, which is cut in a modified pear double rose-cut shape. Since appearing in Europe in the 16th century, the ''Beau Sancy'' has been owned by a number of European royal houses, among them the House of Medici and the Kings of England and Prussia. After more than 300 years in the possession of the House of Hohenzollern, the diamond was sold in 2012 at Sotheby's auction in Geneva for $9.57 million to an anonymous buyer. History The ''Beau Sancy'' comes from the famous diamond mines around Golconda, now in the Indian state of Telangana. Like its sibling diamond, the ''Sancy'', it is part of the stones collectively known as the Golconda diamonds, which also include the Koh-i-Noor and the Hope Diamond. The ''Beau Sancy'' is sometimes also known as the 'Little Sancy' to better distinguish it from its larger sibling. It is unknown when the diamond first reached Europe, but the earliest record of its existence comes when it ...
