They document geological environments, production conditions, and mining methods while collecting A-Type reference samples with documented origins, and observe how rough gemstones are sorted, cut, treated, and traded.<\/p>\n<p align=\"left\">These samples, field records and analytical data become part of the laboratory\u2019s reference system for research and comparison. Field observations do not replace laboratory analysis, but provide source context. Origin determination requires multiple lines of evidence, including microscopic observation, instrumental testing, reference samples, and field records.<\/p>\n<p align=\"left\">During the Q&amp;A, Andrew Lucas discussed origin determination for Feicui from different sources, emphasizing that it cannot rely on a single characteristic or data point, but requires relevant characteristics and supporting evidence.<\/p>\n<p><strong>Bringing Field Research into Gemology Education<\/strong><\/p>\n<p align=\"left\">The event also introduced GUILD\u2019s Field Gemology study programs, bringing learners into mining areas, trading markets, and other industry settings to observe how gemstones move through mining, sorting, processing, and trading.<\/p>\n<p align=\"left\">\u201cIf you don\u2019t go, you don\u2019t know,\u201d Andrew Lucas said, highlighting the importance of field research. Information from gemstone-producing regions and trading sites cannot be obtained solely from laboratory samples. By bringing documented field records and samples back to the laboratory, GUILD builds reference materials supporting gemstone identification, research, and education.<\/p>\n<p align=\"left\"><strong>About GUILD<\/strong><\/p>\n<p align=\"left\">Founded in Los Angeles in 1980, GUILD Gem Laboratories conducts identification, grading, and research on colored gemstones, diamonds, pearls, and jade.<\/p>\n<p align=\"left\">Contact:<br \/>Dany Chen<br \/>chendanning@guildlab.cn<\/p>\n<p>Photos accompanying this announcement are available at <br \/><a href=\"https:\/\/www.globenewswire.com\/Tracker?data=ewxJfbhYvykhniKBj92CAnHjOttF90DFVEcVo3pFlroKir4Mse70YD4Fxif-P87CGEFzE-NATK_NQJlfuP_yhvY-neiNoEqUa28BNLl6kPfgBosT6myl6qAhuwVgOGvVIG_hycOrsJz3u6mfLa5VkfgW_LigSnhbTTF1BtT-bWQEb3nhM5CqMtiOXfZKeumbAjhPCZJzM6YLZMgS8FBDaXEkxjRDaLBxWeAf9CP0Y9viFO3o4eS7jOC0-_gKuEzDOry130iSP47kQOIA45j0Vg==\" rel=\"nofollow\" target=\"_blank\" title=\"\">https:\/\/www.globenewswire.com\/NewsRoom\/AttachmentNg\/d259dd97-87b2-4533-b34a-200adec84a0f<\/a><\/p>\n<p><a href=\"https:\/\/www.globenewswire.com\/Tracker?data=ewxJfbhYvykhniKBj92CAnHjOttF90DFVEcVo3pFlroKir4Mse70YD4Fxif-P87C0XMPzCZb_sG6Ilyr94ZvfzKWJyTeYkHecvpyAYWq-MOZIbI7M_RPhgXWrJE8fg00Nyn5Lyhg-NcOvHlWJ61TMkW7TerWBGGAerD59Ov5hhBmiVtkurMDEILzTV0-PUZTjEQwwuuRTOtL-_RoA1nbtstH7E3UmnVwIB69Dcc0KQAomv-RbNkLOWpOPh9ixtGMJ6TTkGTNKg-iiQRG3b5DQA==\" rel=\"nofollow\" target=\"_blank\" title=\"\">https:\/\/www.globenewswire.com\/NewsRoom\/AttachmentNg\/1e52a1c0-ea57-4586-a9fc-66b3abd3d119<\/a><\/p>\n<p><a href=\"https:\/\/www.globenewswire.com\/Tracker?data=ewxJfbhYvykhniKBj92CAnHjOttF90DFVEcVo3pFlroKir4Mse70YD4Fxif-P87CFL4yQ0TfNRfV0c0YASp536EswPq5OdusgQIP9Aqd5mBKPWSuaugKkgZQk12aO6DVyN04yArpZr3A-HuZt_Q2ShiK2xnKOPB7Vr0-Yo86kHxPPaHE61VfqOrG42jk8a0k3IjRjxa7uCMAd9NHWMxx22C2Eyfqf6tGD0LyhvLOlq3qV5D9-H_iV9CkC74OkF_1BI3i4k5kCPkOYpbmXBUh_g==\" rel=\"nofollow\" target=\"_blank\" title=\"\">https:\/\/www.globenewswire.com\/NewsRoom\/AttachmentNg\/71d50986-646a-4f6c-aaf4-38af1f09e94c<\/a><\/p>\n<p><a href=\"https:\/\/www.globenewswire.com\/Tracker?data=ewxJfbhYvykhniKBj92CAnHjOttF90DFVEcVo3pFlroKir4Mse70YD4Fxif-P87CrxIzy0XYmPmNPv2lX3UplFp2fuQ3OvzzEfKPmydidTD7tzRVSr_VvSpTX0oTVsOw-tPrunOflwc4DFKNvm8mpBWvoedbHJAToh2mitV9ik2Y4nrBcugCKDuES5O25Pmw05uYnfB8IUDeRNGvqCqf9ATYykpuQjrkKv1wuwEn4zQXPIOtWJhmB6jg8yFhSM3TPHivVM13wbdXxNepoHr_PA==\" rel=\"nofollow\" target=\"_blank\" title=\"\">https:\/\/www.globenewswire.com\/NewsRoom\/AttachmentNg\/cd8c2aa4-a1f0-4b63-bd18-620f2d2fc421<\/a><\/p>\n<p><a href=\"https:\/\/www.globenewswire.com\/Tracker?data=ewxJfbhYvykhniKBj92CAnHjOttF90DFVEcVo3pFlroKir4Mse70YD4Fxif-P87ClaCqMkciFFkmsSQT1TOgF4D7P6asoJWPkHfaj7asRnnf73z9W9ex2voOEMsdPJaXMoBu6uxw3MF83cgr6atC6J1VGjhlM7-FnFIK6octo6iZiM4EGEhviASehaQ78Rh84eYRPhjPGrlOmZKO6Ya35PM5e48K54NVj52vq3JrcOZ_Ogha8YTWNtMD16pfvcE_x5OH8W__OaNrYNGYnGKBVg==\" rel=\"nofollow\" target=\"_blank\" title=\"\">https:\/\/www.globenewswire.com\/NewsRoom\/AttachmentNg\/b9a4c493-caba-4f3b-82db-c5121c822c8e<\/a><\/p>\n<p><img alt=\"\" src='https:\/\/ml.globenewswire.com\/media\/YzJmNTJhMWQtY2QyNC00Y2NhLTg2YzUtZmQxNTdiZjVjZjQ2LTUwMDE2NzUzMC0yMDI2LTA5LTExLWVu\/tiny\/GUILD.png' referrerpolicy='no-referrer-when-downgrade' \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>BANGKOK, Sept. 11, 2026 (GLOBE NEWSWIRE) &#8212; GUILD Gem Laboratories hosted its \u201cA Decade in the Field\u201d anniversary event in Bangkok, reviewing a decade of Field Gemology research.
