寶啾寶石 報報： SSEF訊息分享─翡翠篇 寶啾 寶石坊 也有 裸鑽 及 有色寶石 的銷售服務，也可以代客設計加工，歡迎來詢問， 寶啾寶石坊 提供最好的服務及最佳的價位。 Baochu寶啾寶石坊有LINE@了，請透過下方連結將我們加好友。 　 SSEF 日前分析了一個特殊的 翡翠 手鐲(見圖2)和一系列十二枚令人印象深刻高度匹配的鮮豔綠色(帝王綠Imperial green)且高透光度(圖1)的凸圓面寶石。除了這些高品質的物件外，還分析了一些注入樹脂和染色的翡翠玉石，包括破碎後以膠黏合的手鐲(圖2右側)，鑑定結果對我們的客戶來說感到相當詫異。   　正如寶石學家所熟知的， 珠寶 使用的翡翠硬玉不屬於單晶寶石，而實際上是一種岩石種類，主要由微小交鎖狀的鈉鋁矽酸鹽晶體jadeite所組成。許多情況下，這些岩石的礦物組成不均勻，但可能含有輝石類的其他成員(特別是鈉鋁矽酸鹽 (以下稱-硬玉)Jadeite─綠輝石omphacite─鈉鉻輝石Kosmochlor的固溶體)甚至還包含更多的礦物，從而構成在分析和正確命名法應用上的一些問題。 　 　最近在客戶幾件小型雕件的寶石中發現了這種綜合性的案例，該物件在視覺上很像綠色翡翠硬玉(圖3)。   　使用分析化學元素的方法外，主要以多次顯微拉曼光譜分析來看這些樣本含有不同含量的硬玉和 綠輝石 。圓板狀樣本以硬玉為主要組成，而三角板狀樣本實際上由富含鈣-鎂的輝石類-綠輝石以及和介於硬玉至透輝石Jadeite-Diopside固溶體的居中成分所組成(圖4)。因此，這個三角形樣本的正確名稱是綠輝石玉Ompacite-Jade而不是 鈉鋁矽酸鹽 質的翡翠硬玉Jadeite Jade。儘管這種區分看起來相當複雜並且是一項嚴正的科學決策。而必須進一步說明的是，綠輝石明顯比硬玉豐富，在自然界中可以找到相當大量的礦藏。   　根據CIBJO定義，我們認為這是貿易間的重要信息，儘管硬玉和綠輝石可能看起來非常相似，並在市場上皆以「玉─Jade」的詞綴一起使用；2016年香港寶石學協會(GAHK)與香港檢測認證委員會(HKCTC)共同製定和發布的命名後，傳統的術語「 翡翠Fei Cui 」可用於硬玉和綠輝石佔主要成份的岩石(見 www.gahk.org/journal/2017/a07.pdf )。如上所述，硬玉或像硬玉的岩石，暱稱為「朋友」，對於寶石學...
