Gems & Gemology

Gems & Gemology is the quarterly journal of the Gemological Institute of America, a nonprofit educational organization for the gem and jewelry industry, and it has published research on gem materials, synthetics and identification methods since 1934. Its 2025 Journal Impact Factor is 2.4, a second-quartile position in mineralogy.《宝石与宝石学》是美国宝石研究院（Gemological Institute of America）出版的季刊，该院是服务宝石与珠宝行业的非营利教育机构。本刊自 1934 年起刊载宝石材料、合成品与鉴定技术方面的研究，2025 年期刊影响因子为 2.4，在矿物学类目处于第二四分位。

Scope

• The journal welcomes submissions on all aspects of the field, and the remit reaches from laboratory bench work to the commercial and historical sides of the gem trade.本刊欢迎这一领域各个方向的投稿，范围从实验室台面工作一直延伸到宝石贸易的商业与历史层面。
• Laboratory or field research heads the list of topics, which puts bench work and fieldwork on the same footing.实验室研究与野外研究排在选题清单首位，台面工作与野外工作因此处在同一层级。
• Notable gem materials and localities come next, a slot that takes in new finds along with long-known sources.重要宝石材料与知名产地紧随其后，新发现与老产地同在这一类。
• Synthetics, imitations and treatments form the third topic, a cluster that runs from laboratory-grown stones to treated ones.合成宝石、仿制品与各类优化处理合为第三类，从实验室培育宝石一直排到经过处理的宝石。
• New instruments or identification techniques are named as a topic in their own right, giving method papers their own slot.新仪器与新鉴定技术单列为选题，方法类论文因此有独立的归口。
• Trade and business matters also belong to the scope, and the list ends with jewelry manufacturing arts and with historical jewelry and museum exhibits.贸易与商业事务同样在范围之内，清单末尾则是珠宝制作工艺以及历史首饰与博物馆展陈。
• Gem News International runs brief reports capped at four figures and one thousand words, keeping short field notices inside the journal.Gem News International 刊登简报，上限为 4 幅图与 1000 词，短小的现场记录因此留在本刊之内。
• Micro-World allows one or two figures and six hundred words, and the slot is built around photomicrography of inclusions and internal features.Micro-World 允许 1 至 2 幅图与 600 词，这一栏目围绕包裹体与内部特征的显微摄影设置。
• Lab Notes prints reports written by staff of the GIA laboratory, so a routine identification result can reach print without a full research article.Lab Notes 刊载研究院实验室员工撰写的报告，常规鉴定结果无须写成完整研究论文即可面世。
• Colored Stones Unearthed and Diamond Reflections carry their own editors and a fixed theme, the first on colored gemstones and the second on diamonds.Colored Stones Unearthed 与 Diamond Reflections 各有专职编辑与固定主题，前者谈彩色宝石，后者谈钻石。
• From the Field and Charts are followed by In the Spotlight, and the guidelines treat all of these departments as edited but not peer reviewed.From the Field 与 Charts 之后还有 In the Spotlight，作者指南把这些栏目一律视为经编辑审读而不做同行评审的部分。
• A manuscript may therefore aim at a full research article or at one of the shorter departments, and the two routes differ in how deeply the work is read.投稿既可瞄准完整研究论文，也可投向较短的栏目，两条路径的审读深度并不相同。
• The masthead describes the publisher as a nonprofit educational organization for the gem and jewelry industry, which places the journal inside a teaching body rather than a commercial press.刊头把出版方界定为服务宝石与珠宝行业的非营利教育机构，本刊因此隶属一所教学机构，而非商业出版社。

History

• Robert M. Shipley founded the Gemological Institute of America in 1931, and the institute has remained the publisher of the journal ever since.1931 年 Robert M. Shipley 创办美国宝石研究院，该院此后一直是本刊的出版方。
• Shipley brought out the first issue of Gems & Gemology in 1934, three years after the institute opened.1934 年 Shipley 推出《宝石与宝石学》创刊号，距研究院成立三年。
• Volume numbers do not map one volume onto every calendar year, so the volume printed on a 2026 issue cannot be used to count back to the founding date.卷号与日历年不构成一一对应的关系，2026 年某一期上的卷次无法用来倒推创刊年份。
• The summer 2026 issue is Volume 62, Number 2, and a volume now takes in four numbers spread across a single year on a quarterly schedule.2026 年夏季号为第 62 卷第 2 期，每卷 4 期，按季度在一年之内出齐。
• A full-colour format arrived in 1982, and fifteen awards followed over the next twenty years.1982 年刊物改为全彩版式，此后二十年间获得 15 个奖项。
• Richard T. Liddicoat edited the journal and became president of the institute in 1952, and the GIA library now bears his name.Richard T. Liddicoat 曾任本刊主编，并于 1952 年出任研究院院长，研究院图书馆以他的名字命名。
• The digital backfile in Crossref opens at Volume 17, Issue 4, dated 1981, which marks the start of the scanned archive and not the start of the journal.Crossref 的数字回溯始于 1981 年第 17 卷第 4 期，那是扫描存档的起点，与创刊时间并无关系。
• The journal is abstracted in Current Contents: Physical, Chemical & Earth Sciences and in Science Citation Index Expanded, and Chemical Abstracts, GeoRef and Mineralogical Abstracts appear on the same list.本刊被 Current Contents 的物理、化学与地球科学分册以及 Science Citation Index Expanded 收录，Chemical Abstracts、GeoRef 与 Mineralogical Abstracts 同在这份清单上。
• The 2025 Journal Impact Factor is 2.4 and the five-year figure matches it, both taken from the Journal Citation Reports released in June 2026.2025 年期刊影响因子为 2.4，五年影响因子与之持平，两项数据取自 2026 年 6 月发布的期刊引证报告。
• Journal Citation Reports ranks the title 12th of 30 in mineralogy, a Q2 place in the Science Citation Index Expanded edition.期刊引证报告把本刊列在矿物学类目 30 种期刊中的第 12 位，属 Science Citation Index Expanded 版次的 Q2。
• Four earlier readings run 2.045 for 2022, 1.6 for 2023, 2.6 for 2024 and 2.4 for 2025, a line that rises and falls rather than climbing steadily.此前四次读数依次为 2022 年 2.045，2023 年 1.6，2024 年 2.6 与 2025 年 2.4，走势有升有降，未见持续上行。
• Annual output comes to about twelve articles, total citations stand near 962 and a cited half-life of 11.4 years points to a literature that turns over slowly.年发文约 12 篇，总被引接近 962 次，11.4 年的被引半衰期说明相关文献更替较慢。
• Crossref records for 2026 list Volume 61, Issue 4 beside Volume 62, Issues 1 and 2, which shows the quarterly run continuing without gaps.Crossref 的 2026 年记录里，第 61 卷第 4 期与第 62 卷第 1、2 期并列，季刊的出版节奏延续未断。
• The copyright line names the institute itself rather than an outside press, and the serial is registered under ISSN 0016-626X for print with 2376-4473 for the electronic edition.版权行署名为研究院本身，该刊纸本刊号为 ISSN 0016-626X，电子刊号为 2376-4473。
