It details critical parameters including facet angles for a refractive index of 1.540, pavilion and crown patterns for a 96-index gear, and specific dimensional requirements for the stone width and girdle thickness. The guide emphasizes the importance of precision in faceting, offering clear guidelines for competition scoring, material selection, and polishing standards.",{"@graph":14,"@context":66},[15,34,49],{"@type":16,"itemListElement":17},"BreadcrumbList",[18,23,27,31],{"item":19,"name":20,"@type":21,"position":22},"https://docshare.wps.com","Home","ListItem",1,{"item":24,"name":25,"@type":21,"position":26},"https://docshare.wps.com/document/","Document",2,{"item":28,"name":29,"@type":21,"position":30},"https://docshare.wps.com/document/lifestyle/","Lifestyle",3,{"item":32,"name":10,"@type":21,"position":33},"https://docshare.wps.com/document/barround1-2004-usfg-ssc-novice-gemstone-cutting-instruction/657901/",4,{"url":32,"name":10,"@type":35,"author":36,"headline":10,"publisher":39,"fileFormat":42,"inLanguage":8,"description":12,"dateModified":43,"datePublished":43,"encodingFormat":42,"isAccessibleForFree":44,"interactionStatistic":45},"DigitalDocument",{"name":37,"@type":38},"supergirl","Person",{"url":19,"name":40,"@type":41},"DocShare","Organization","application/pdf","2026-10-26",true,{"@type":46,"interactionType":47,"userInteractionCount":4},"InteractionCounter",{"@type":48},"ViewAction",{"@type":50,"mainEntity":51},"FAQPage",[52,58,62],{"name":53,"@type":54,"acceptedAnswer":55},"What are the required dimensions for the stone width?","Question",{"text":56,"@type":57},"The stone width should be 10 mm, measured flat to flat, with an allowed margin of plus or minus 0.5 mm.","Answer",{"name":59,"@type":54,"acceptedAnswer":60},"What refractive index is this cutting design intended for?",{"text":61,"@type":57},"This design is calculated for a refractive index of 1.540.",{"name":63,"@type":54,"acceptedAnswer":64},"How is the girdle evaluated in this competition?",{"text":65,"@type":57},"The girdle must be polished and is judged under the same categories as other facets, with two additional categories specifically for girdle thickness and uniformity.","https://schema.org",{"og:url":32,"og:type":68,"og:title":10,"og:site_name":40,"og:description":12},"article",{"robots":70,"canonical":32},"index,follow",{"doc_id":72,"site_id":7},657901,1792993849,{"code":4,"msg":75,"data":76},"success",[77,81,85,89,94,99,104,109,114,117,120],{"id":22,"doc_module":4,"doc_module_name":25,"category_name":78,"show_sort_weight":79,"slug":80},"Story & Novel",90,"story-novel",{"id":26,"doc_module":4,"doc_module_name":25,"category_name":82,"show_sort_weight":83,"slug":84},"Literature",80,"literature",{"id":33,"doc_module":4,"doc_module_name":25,"category_name":86,"show_sort_weight":87,"slug":88},"Exam",70,"exam",{"id":90,"doc_module":4,"doc_module_name":25,"category_name":91,"show_sort_weight":92,"slug":93},5,"Comic",60,"comic",{"id":95,"doc_module":4,"doc_module_name":25,"category_name":96,"show_sort_weight":97,"slug":98},6,"Technology",50,"technology",{"id":100,"doc_module":4,"doc_module_name":25,"category_name":101,"show_sort_weight":102,"slug":103},7,"Healthcare",40,"healthcare",{"id":105,"doc_module":4,"doc_module_name":25,"category_name":106,"show_sort_weight":107,"slug":108},8,"Research & Report",30,"research-report",{"id":110,"doc_module":4,"doc_module_name":25,"category_name":111,"show_sort_weight":112,"slug":113},9,"Religion & Spirituality",20,"religion-spirituality",{"id":112,"doc_module":4,"doc_module_name":25,"category_name":115,"show_sort_weight":112,"slug":116},"World Cup","world-cup",{"id":118,"doc_module":4,"doc_module_name":25,"category_name":29,"show_sort_weight":118,"slug":119},10,"lifestyle",{"id":121,"doc_module":4,"doc_module_name":25,"category_name":122,"show_sort_weight":90,"slug":123},19,"General","general",{"code":4,"msg":75,"data":125},{"doc_id":72,"user_id":126,"nickname":37,"user_avatar":127,"doc_module":4,"category_id":118,"category_name":29,"doc_title":10,"doc_description":12,"doc_content":128,"file_id":129,"file_url":130,"file_type":131,"file_size":132,"view_count":4,"is_deleted":4,"is_public":22,"is_downloadable":22,"audit_status":22,"page_count":22,"language":133,"language_code":8,"site_id":7,"html_lang":8,"table_of_contents":134,"faqs":135,"seo_title":136,"seo_description":12,"update_tm":73,"read_time":26},962088121634,"https://ap-avatar.wpscdn.com/davatar_9964176cb1d06d4a9deccf72a44ae3dc","66  \n72  \n78  \n\n| \u003Cbr>C\u003Cbr>|\n| --- |\n|  |\n| \u003Cbr>P\u003Cbr>|\n\n30  \n24  \n18  \nBarRound1 by Bob Keller  \n2004 USFG SSC Novice Stone Material Any  \nAngles for R.I. = 1.540  \n37 + 16 girdles = 53 facets 2-fold radial symmetry  \n96 index  \nL/W = 1.000 T/W = 0.727 U/W = 0.145 P/W = 0.466 C/W = 0.237  \nVol./W³ = 0.274  \nPAVILION  \nP1 43.00° 96-06-12-18- 24-30-36-42- 48-54-60-66-  \n72-78-84-90 G 90.00° 96-06-12-18- 24-30-36-42- 48-54-60-66-  \n72-78-84-90  \nCROWN  \nC1 60.00° 96-06-12-18- 30-36-42-48- 54-60-66-78- 84-90  \nC2 42.00° 24-72  \nC3 28.00° 24-72  \nC4 14.00° 24-72 T 0.00° Table  \nC:\\Faceting\\GemCad\\2004SSC\\Novice_Pattern.gem  \nNOVICE-Bar Round 1, by B.
