Emerald祖母綠

CE(O): Grading of clarity enhancement of emeralds – 祖母綠凈度優化分級

1.  None 無油2.  Insignificant 極微油3.  Minor 微油4.  Minor to moderate 微到中油5.  Moderate (filler mentioned if resin) 中等油(如有充膠會標注)6.  Significant (filler mentioned if resin) 重等油 (如有充膠會標注)


The comment ‘Non-enhanced clarity features present’, indicates the presence of empty or dried out fissures at the time ofexamination.

“可見凈度未優化特征”這一標注說明在GRS檢測這顆祖母綠的時候,可以觀察到內部全凈或已完全干燥的縫隙特征。(大未解讀:這個一般是用在無油祖母綠的檢測中,要么就是晶體全凈,要么就是由內部縫隙但縫隙是干燥的,這個主要是為了在GRS的記錄中留下相關記錄,以備下次再次檢測同一顆祖母綠時做參考)

 

Other possible treatments specified on GRS gemstone reports:其他GRS證書中常見的處理種類有:

·       Coating 覆膜·       Dyeing染色·       Application ofcolorless oil/ or epoxy-like resins and/or wax使用無色油和/或者樹脂類和/或蠟·       Irradiation, useof nuclear bombardment 使用原子轟擊的輻射處理·       Conventionalsurface diffusion, or any combination of the above 傳統的表面擴散或者以上處理方式的組合


Other possible comments on GRS reports GRS證書上其他常見的備注:


PL tested

The stone has beentested with a photoluminescence spectrometer. Go to ‘Analytical Methods’ for more details.

PL檢測指光致熒光光譜儀(Photoluminescence Spectrometer)檢測,請參考分析方法的具體解釋

(大未解讀:這種測試主要用于無損檢測寶石成分和微量元素等)


LIBS tested

The stone has beentested with a laser-induced breakdown spectrometer. We use this method to checkheated sapphires for possible beryllium-diffusion treatments. Go to ‘Analytical Methods’ for more details.

LIBS檢測指激光誘導穿透光譜儀(之前大未文章有專門介紹輕松了解寶石檢測專業儀器之 – LIBS –激光誘導穿透光譜儀),主要使用這種方式檢測藍寶石是否經過可能的鈹擴散處理,請參考分析方法的具體解釋


Raman tested

The stone has beentested using a Raman spectrometer. This test is often used to identify mineralsor individual parts of gems or ornamental objects. Go to ‘Analytical Methods’ for more details.

激光拉曼光譜儀檢測經常用來檢測確認礦物、寶石以及古玩等的成分,請參考分析方法的具體解釋


FTIR tested

The stone has beentested using a FTIR spectrometer. Go to ‘AnalyticalMethods’ for moredetails.

傅里葉紅外光譜檢測,請參考分析方法的具體解釋


EDXRF tested

The stone has beentested using a EDXRF spectrometer. EDXRF spectrometers are used to analysethe chemical composition of the tested material. Go to ‘Analytical Methods’ for more details.

X射線熒光光譜分析儀,這種儀器用來分析檢測材料的化學成分組成,請參考分析方法的具體解釋。


Important information and limitation of the use of GRS Gemresearch Swisslab gemstone reports

All GRS Gemresearch Swisslab AG gemstonereports will be printed on original paper (marked with GRS) and will bear anofficial signature. No corrections or alternations of any form shall beaccepted on the gemstone report. All gemstone reports are laminated forprotection. The gemstone reports trademarks such as GRS, H(a), E(IM), GRS-type‘pigeon’s blood’ or service marks of GRS Gemresearch Swisslab AG may not bereproduced in whole or in part without the prior written authorization of GRSGemresearch Swisslab AG. This GRS report must contain two GRS hologramsotherwise this report is not valid. A GRS Gemresearch Swisslab AGgemstone report contains the identification of gemstones by photographicimages, descriptions, dimensions and weight. It states an opinion on theirauthenticity, treatment, country of origin (if determinable), quality andrarity (does not always apply). This GRS report does not constitute a guaranteefor or an appraisal of the object or gemstone described there in. The physicalappearance of an object or gemstone may differ from its photographic image onthe gemstone report. Determination of the authenticity and country of origin ofa gemstone is based on the analysis of its chemical and physical properties andinternal characteristics (e.g. inclusions and growth structures) using standardgemological instruments and modem analytical instruments includingspectrometers. The conclusion on the country of origin, authenticity andtreatment of gemstones is an opinion of the laboratory based on the directcomparison of the findings with those obtained from the analyses of referencematerials, as well as those in published literature. The laboratory to theextent reasonably possible continuously updates this knowledge.

關于使用GRS證書的重要信息及有限責任提示:

所有GRS證書都是使用清晰標注GRS字樣的印刷原件并以覆膜保護,內頁有官方簽字,文字內容不會有任何形式的更正或涂改GRS證書上的商標專用字樣如GRS, H(a),GRS-type “pigeon’s blood ”以及GRS Gemresearch Swisslab AG未經許可禁止復制正版GRS證書有兩個全息碼,證書包含照片、描述、尺寸、重量、天然性、優化處理、產地(如可以判斷)以及質量和稀有度(非必備)等信息。GRS證書并不代表對于鑒定物提供品質擔保或價值評估,鑒定物的實際觀感可能和照片有所出入,對鑒定物真偽及產地的意見是基于對其物理、化學性質以及內含物特征(如包體及生長結構)的使用常規和現代分析儀器獲取的數據與本實驗室的參考標本以及已出版的資料的對比分析得出,僅代表GRS實驗室的意見,本實驗室一直不斷更新標本庫及相關的最新資料。
