American ideals cufflinks cut has changed dramatically

Henry by 20 years (since 1860-1880), efforts, gradually acquired the diamond brightness and fire a fully reflect the proportion of cufflinks cut to become a famous diamond cufflinks processors. Henry was first introduced cufflinks cut the table smaller, only a whole cufflinks cut-third, while the higher of the crown, about two-thirds of the pavilion. An increase of 8 facets around close to the table, kite increase in the number of facets of the crown, resulting in crown inclined facets 40 (see below). Japan has a lot of specialized collection of cufflinksowners. Cufflinks cut the proportion: 35 crown angle, pavilion angle of 41 units wide by 40%, the full depth of more than 60%. This has been today the proportion is closer.
Thor Minkowski of Marcel Tolkowsky (1899-1991) was a scholar, was born in Belgium Cutting family, it is processing a better understanding of his diamond cufflinks. Processing industry the most important contribution is the use of scientific arguments summed up the type of diamond cufflinks cut the proportion of his diamond cufflinks. As long as there are new cufflinks released, they will be favorites.  By calculating the cuff cut type, especially Henry cufflinks cut processing in various proportions, summed up the standard ratio set to demonstrate a fire color and brightness of the diamond, which is in his famous " Diamond Design "(Diamond Design") (1919), a book put forward the so-called ideal cufflinks cut, that is, wide-to 53%, crown angle 34.5.
 Pavilion angle of 40.75 for the full depth ratio of 59.3%, waist thick 0.9%, the size of the bottom facet of 1.3%. This is the first book based on optical principle to calculate the proportion of diamonds. He introduced, this proportion is known as Thor Minkowski cufflinks cut type (Figure 2). Although the book is published in English, similar to the proportion of his proportion of Americans Henry, and the first U.S. diamond industry with diamond processing by the proportion of cufflinks are more popular in the United States and considered to be the best cufflinks cut, it is also known as the American ideal cufflinks cut or the United States bright cufflinks cut type. Some fans even set up a club, or spare a dedicated exhibition room for everyone to enjoy the cufflinks.
But Thor Minkowski cufflinks shape of cut or American ideals cufflinks cut has changed dramatically: the end of tip into a point-like pavilion facets variable length many (Figure 3). The American Gem Society (AGS) Thor Minkowski proportion slightly modified in the 1950s as a standard of evaluation cut, modify limited to slightly widen the table, and joined the Girdle thickness. GIA is also ideal cufflinks cut type as an evaluation standard cut. This shows symbols and mark are welcomed by the people to integrate the cufflinks. Thor Minkowski ideal cufflinks cut the proportion of after two round brilliant cufflinks cut type, 1939-1940 by the introduction of the Yi Puluo (New Blade) perfect cufflinks The shape of cut and the 1969 launch of the Scandinavian standard cufflinks cut type, and the International Diamond Council cufflinks cut type.
Fancy cufflinks cut actually the whole development is parallel. Fancy cuff links the emergence of cut-type can be traced back to 500 years ago, the 16th century, when there is stepped cufflinks cut type. We can make a large number of products and cufflinks. Subsequent As cufflinks processing techniques become more sophisticated, there have been some bright-shaped fancy cufflinks cut type. After the 1950s, a variety of fancy cufflinks cut type are constantly emerging, has greatly enriched the shape of cut styles of gemstone cufflinks. Lily cufflinks cut type (Lily Cut) star in the sky (Sky Star) odd the alchemist cufflinks cut type.
