有关紫黄晶的一篇文章(1)

刚看到一篇英文介绍紫黄晶的文章，转过来给大家看。翻译得不好请见谅，有不同意见大家探讨，我也是新手，不知道这篇文章对不对。哭死了，搞了半天发送的时候超时了，结果要重新来过，大家看在我努力敲字的份上给点赏吧～～这里说紫黄晶是非常纯净的，并没有很多的瑕疵，为什么大家都说有棉裂是鉴别天然的依据？如果这篇文正确，其实那是切割大晶体以后剩下的废料啊，集体被误导了。 First, it is crucial to learn as how Ametrine comes into existence naturally. When quartz containing high iron impurities is exposed to different temperatures it results in oxidation. The 50% of the quartz bears high temperature on its surface while rest 50% slightly cool temperature. In this way quartz balances the two extreme temperature intensity at the time of crystallization. Thus, two different colours are produced and Ametrine is formed. This process occurs rarely and so is genuine Ametrine. 首先，认识到紫黄晶是如何天然形成的很重要。当含铁量很高的石英暴露在不同的温度下会被氧化。如果一半石英表面温度很高而另一半则稍低，石英在结晶过程中会平衡不同的温差，从而在晶体中形成两种不同的颜色，这就是紫黄晶。这个过程的发生非常罕见，一如天然紫黄晶。 A mine known as Rio Grande do Sul at Brazil is said to produce this beautiful gemstone first. Now, natural Ametrine is procured from only one mine in the world that is Anahi Mine at Bolivia. In any case Ametrine from Bolivia is more valuable than the one obtained from Brazil. However, there are many in genuine gemstones sold as Ametrine in the market. These are synthetic Ametrine that are produced in Russia. Basically it is simulated amethyst. Half of amethyst gemstone, purple in colour is heated with yellow heat/light to produce yellow colour of citrine. These synthetic gems look quite identical to the natural Ametrine. The buyers can identify the true stone on the basis of colour, clarity, cut and carat weight. 据说巴西的Rio Grande do Sul矿洞首先发现这种美丽宝石。现在全世界的天然紫黄晶都产自唯一的玻利维亚Anahi矿区。任何情况下，出自玻利维亚的紫黄晶都比产自巴西的更有价值。然而市场上有许多挂着紫黄晶名义销售的其他宝石，这些是俄国出产的人造紫黄晶。根本上这是人工处理的紫水晶，紫水晶的一半被黄热/光加热后产生黄水晶的黄色。这些假造紫黄晶和天然的看上去非常相似。顾客可以基于颜色，净度，切割和克拉重量区分天然紫黄晶。
