诗中“胜美玉”,“过冰清”,写出水晶的质地美,而“亦欲应时明”则描绘出水晶充满灵性的动态美,耐人寻味。罗维是有独特眼光,懂得水晶真谛,第一个称赞水晶超过美玉的伟大诗人。他的认识已被千年之后的科学理论所证实;以水晶为直接吟咏对象的诗篇还有:

晶及其石英岩类玉石是中低档宝玉石,虽比不上钻石、红蓝宝石的高贵,但在加工中如果构思巧妙而且加工精细,同样具有很高的价值。如中国传统的玛瑙“虾盘”、“龙盘”、“水漫金山�?水胆玛瑙摆件)都被誉为国家级宝玉石。

水碧:《山海经》中,水晶又被称作水碧: �?又南三百里,日耿山,无草木,多水碧 �?,郭璞注�?�?亦水玉类 ”。这种称谓常被文人所引用,晋代郭景纯《璞江赋》道�?�?鬼,水碧�?�?。水晶又有人称它叫玉瑛。《符瑞图》载�?美石似玉,水精谓之玉瑛也�?”

条痕颜色:无色。矿物粉末的颜色叫条痕。它可以消除假色,减弱他色,保留自色,是比矿物的颜色更为可靠的鉴定特征之一。

幽灵水晶,分绿幽灵,红幽灵,白幽灵等,主要组成为绿泥石,其中绿幽灵属于珍贵品种。

地质学家目前为止对晶洞形成还没有广泛认同的理论,但相信晶洞可以在任何埋藏的空腔内形成。这些空腔可以是火成岩中的气泡、树根下的空穴,甚至动物挖的地洞。经过漫长时间,空腔的外壁变硬,溶解的矽酸盐或方解石沉积到内壁。再经过漫长的时间,缓慢渗入的矿物使得晶体在空腔内部结晶。

在透明的水晶中,隐裂纹呈亮晶晶的片状,有时还会有晕彩效应。这些裂纹是水晶在生长过程中,遇到外力挤压而在内部产生的一些隐形裂纹,隐裂纹在芙蓉石、紫水晶、白水晶球及白水晶柱中都很常见。有的裂纹后来被物质填充,形成愈合的裂纹,也就是原来的裂纹又长住了。这种裂纹对水晶的影响相对要小一些。

With the Cambridge English Corpus The tridymite crystals are rectangular or wedge-shaped and are sometimes organized in aggregates. Through the Cambridge English Corpus Moreover, haloarchaeal cells were embedded within just salt crystals below laboratory circumstances and subsequently analysed by light microscopy. In check here the Cambridge English Corpus The white clouds (typically sparse) had been also commonly considered becoming made up of little crystals of h2o ice, relatively like cirrus in our environment. Within the Cambridge English Corpus They are present in evaporite salt lakes and may be trapped in salt crystals all through evaporation. Through the Cambridge English Corpus For that reason, the cells (organelles and membranes) are wrecked mechanically by ice crystals, bringing about death by way of mobile lysis. With the Cambridge English Corpus The crystals were being used in the first or next orders of reflection. From your Cambridge English Corpus Inside our 8xperiments, the crystals ended up cubes using a base place of 8 e mm.
