Natural citrine is very rare. Large quantities of amethyst, usually of lesser quality, are heated to turn it yellow or orange and sold as "citrine." Because the color is now caused by finely distributed iron minerals (mostly hematite and goethite), heated amethyst is not citrine in the strict sense, and also shows no dichroism in polarized light.
Thin coatings of iron oxides on colourless quartz, as well as inclusions of yellow iron oxides ("limonite"), may simulate citrine.

是的黃水晶都是燒出來的.謝謝大家的回答)
非也，並不是所有的黃水晶都是燒的，而是天然的黃水晶才是珍品。
手邊剛好一顆天然無燒100多克拉的，貼來比對一下。
有燒無燒價格差很大，就跟ruby有燒沒燒一樣。沒燒的寶石半寶石通常在大盤那邊都被選走了，
因為根本供不應求。
你這水晶洞的價格5,7,8樓已經解釋的很清楚了，就當繳學費吧。
有無加熱過，送去寶石張那邊，儀器鑑定生死立判。
個人收藏寶石半寶石都是直接從大盤購買，一來夠便宜(只有銀樓賣價的2折左右)，2來沒燒的好貨
通通在那。省下不少時間與金錢。
