对这类水晶晶簇观赏石的欣赏与评价,主要是强调晶体的完整、品种的名贵(如紫水晶、烟晶、发晶等)、造型奇特、含有名贵晶体(如辰砂、辉锑矿等)伴生等。晶簇产于矿床晶洞中,长相完美的并不多见,要完整无损地采集下来,又比较困难,故而采集起来代价较大,精品晶簇价值也就昂贵了。

12He tried yet again in many other cities and succeeded with Crystal Caramels.他又在其他几个城市再次尝试,并成功制出了水晶焦糖。

天然水晶是不可再生资源,随着开发的深入,天然水晶存量已越来越少,为了可持续发展,东海县政府早就制定了保护本地资源,鼓励开发海外水晶资源的政策,但是,海外资源也越来越少,很多国家都提高了开采和出口天然水晶的门槛,进入东海市场的外国水晶价格连年暴涨,其中观赏水晶比普通水晶涨价更快。

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�?”

. These four structures comprise the vast majority of binary crystals with equal figures of cations and anions.

, has the same composition, but There's two possibilities for selecting the holes that the atoms will occupy. The third layer is usually placed in excess of the atoms of the very first layer, making an alternate layer sequence A

解理:无解理。所谓解理是指矿物被打击时,沿一定方向有规则地裂开形成光滑平面的性质。根据解理的程度可以分为五类:极完全解理、完全解理、中等解理、不完全解理和无解理,水晶属于无解理。

水晶常以晶簇、晶洞形式产出,其中水晶洞一般存在于由火山喷发而形成的巨厚熔岩流层的火成岩与玄武岩中。火山喷发时所含的气体或热水溶蚀等作用导致岩层中出现大量的孔隙,当富含硅质矿物的流体进入较薄的熔岩孔隙中,且温、压条件合适时将结晶沉淀出水晶等矿物。

颜色:无色,浅至深的紫色,浅黄、中至深黄色,浅至深褐、棕色,绿至黄绿色,浅至中粉红。

用手去触摸水晶,天然水晶通常温度要比人造水晶的要凉的多;用眼观察,天然水晶通常有棉絮状的包裹体,这个是人造水晶所没有的。

There are just a few diverse device-cell styles, so many different crystals share only one unit-mobile sort. An important characteristic of the unit cell is the volume of atoms it consists of. The total amount of atoms in the complete crystal is the quantity in Every single cell multiplied by the number of device cells. Copper and aluminum (Al) Every have one atom for every unit cell, though zinc (Zn) and sodium chloride have two. Most crystals have only a get more info few atoms for each unit cell, but there are some exceptions. Crystals of polymers, such as, have 1000s of atoms in Each individual device cell.

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。
