What is tsavorite garnet?

Tsavorite is the green variety of grossular garnet, colored by vanadium and chromium, first found in 1967 near the Tsavo National Park on the Kenya-Tanzania border. Tsavorite is the variety; the species is grossular garnet, and a laboratory report prints both. GIA gives garnet a Mohs hardness of 7 to 7.5 and describes its toughness as "fair to good"; Mohs is scratch hardness only and says nothing about chipping.

Is tsavorite treated?

The AGTA Gemstone Information Manual assigns tsavorite the enhancement code N, defined as "Natural: No modification (or currently has no known modification process)." On that basis, and on our own examination, we assess a tsavorite as untreated unless its listing says otherwise; that is our assessment, not a laboratory finding. Clarity enhancement is used on a minority of stones, and this collection includes one stone labelled clarity-enhanced.

沙弗萊石裸石

沙弗萊石是甚麼

沙弗萊石是綠色的鈣鋁榴石，屬於石榴石，並非藍寶石或祖母綠。它的綠色來自微量的鉻和釩，色調深淺因石而異，所以每顆寶石都以實物相片及影片展示。化驗報告會同時列出品種名稱和礦物種名稱。喜歡綠色系藍寶石的買家，可比較綠色藍寶石，或瀏覽我們的寶石。

產品頁面列明的資料

本系列每顆寶石獨立上架，附該寶石本身的相片及影片，以及化驗報告所載的重量、尺寸、形狀、切割及顏色等資料。每件產品頁面均說明該寶石的處理情況；如化驗報告載有相關項目，我們按報告原文照錄。價值較高的寶石附美國寶石學院（GIA）報告，產品頁面列出報告編號；如報告由其他化驗所發出，頁面會註明化驗所名稱。

產地與採購

Crescent Gems 的採購及切割工作以斯里蘭卡為基地。每顆沙弗萊石的產地以產品頁面為準；如化驗報告未載產地意見，頁面所列產地是我們自己的採購紀錄，並非化驗結論。
