This U.S. edition was made with common U.S. cutters' practices and expectations in mind. Alex's ear1iest designs were done to create simple and easy cuts for small stones to be mounted in jewelry pieces. hence the word \"Mini\" in the names of many of them. Some were designed for the 32 and 48 index gears: these have been transposed respectively to the  \n64 and 96 gears.  \nAbout the middle of 1993 Alec and I agreed to put out this U.S. edition. For two years letters have gone back and forth discussing various designs and design features. So many minor changes have taken place that I have lost track of them all. We have agreed to modify the pavilion indexing on several designs to obtain a more even distribution of reflected light from the culet facets. To obtain the graphics I have put all these designs into my computer program, and in doing so have verified all angles. If the angles given here are different from other published versions, it does not mean that those previous versions are wrong in any sense. I wish to thank Alec for his cooperativeness and open-mindedness. Alec would fike to thank Piet van Zanten, of the Netherlands, for his generous computer contributions, and also Robert Long for his advice and computer help. ·  \nStone Color: For some designs Alec gave additional sets of angles for medium to dark colored stones. Lowering the crown to lighten dark material is such common practice here that I have ncx included all these variations. Besides, how much to alter the stone's height depends upon each individual stone's color, and if very dark in color the cutter may decide to ignore light return altogether and cut a shallow pavilion as well (cutting for color) .  \nMaterial and RI: Because small stones used in jewelry are usually natural materials, I have used 41° for the culet for Rl=1 .7 and higher.  \nAngles: Many of Aleo's designs are not strictly 'cookbook' designs, but allow and expect that they will be altered to meet varying circumstances, some of which he tries to anticipate. However, here in the U.S. cutters have come to expect exact angles and dimensions to be given on a design, with the tacit assumption that alterations can and will be made by the cutter. We have here in the U.S. become so used to converting angles that I have not considered the inclusion of other sets of angles for different materials essential. Beginners need exact angles: advanced cutters know how to adjust angles and are expected to do so, but gMng at least one set of exact angles gives the cutter a solid jumping-off place for any alterations he may wish to make.  \nNames & Pages: In corresponding with Alec I needed an easy way to refer to the various long-named cuts arid added the add ional labels AW-1, AW-2, etc.. These have proved so helpful for me that with Alex's permission I have left them in so you, the cutter, can also use them in corresponding about any problems you might have in cutting. There are two pages of alternate crowns: these have been numbered Page 17A and Page 19A so as to keep the page numbers throughout the same as the AW numbers, to make locating designs by number easier. A name ending with CC indicates it is a Cut-Corner shape, CC=Cut Corner.  \nSymbols: The Letter connected to a lassoo stands for the length of the line the lassoo is around. Its length is compared to W. D is the diagonal distance measured as shown. HM/ is the sum of CM/ and P/W plus 0.02","cbCaih7cp5icgkJ2","https://ap.wps.com/l/cbCaih7cp5icgkJ2","pdf",4894506,"English","# Introduction\n## Edition purpose and computed angles\n## Stone color, material, and RI assumptions\n## Angles and cutter expectations\n## Naming, pages, and reference symbols\n## Measurement, preforming, and ratio guidance\n## Design matching vs. dimensions\n## Aw. design list","[{\"question\":\"What is the goal of this U.S. computed edition of Wolkonsky’s designs?\",\"answer\":\"It provides a first computed U.S. edition of Alexandre Wolkonsky’s faceting layouts using common U.S. cutters’ practices.
