8Where will we get this magic wand and crystal ball?我们到哪里获得这种魔棒和水晶玻璃球？
A elementary thought in crystal constructions could be the device cell. It's the smallest unit of volume which allows identical cells to become organized together to occupy all out there House. The geometrical foundation of all crystals is the lattice. A lattice is usually viewed as a daily and infinite arrangement of details or atoms, where Every level or atom has An analogous surrounding surroundings.
发晶的价值取决于发的颜色、罕见性及大小，一般是发色鲜艳、块度大的价格高。水胆水晶的价值主要取决于水胆及晶体的大小、透明度的高低。如果水胆较大并有一定形态，便可加工成较为珍贵的工艺品。另外水胆中的水也有一定的科学研究价值，通过它们可了解几百万年前地球上水的成分及变化。

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。
These illustrations are from corpora and from sources on the net. Any views while in the examples will not depict the viewpoint on the Cambridge Dictionary editors or of Cambridge University Press or its licensors.
石英：《广雅》称水晶叫石英，色白如莹者又叫白。为附的异形字。司马相如《子虚赋》就�?�?雌黄�?�?之句。苏林解释：�?�?，白石英�?”。
Crystals are practically nothing over an requested arrangement of molecules or atoms. Crystals are available many different sizes and shapes, and each one has unique traits. Whatever they are made of establishes how it's going to type.
仿制钛晶树水晶：钛晶是水晶里价格最昂贵的，造假者当然也不会放过这么好的产品。天然的环境下，在水晶里能生长个像树一样的钛晶，完全是可能的，只是这样的货很少，那我们的造假专家是如何做的呢，白水晶底下打个洞，激光打点成板状的钛晶进去，就这样这块水晶的身价就能飙升几十倍。往往有的钛晶戒面，会采用将钛晶部位割成板状，与圆面的水晶粘合的方法来制作。
看文化：水晶里面的包裹体象形，能与文化、宗教及历史有所牵连的话，价格往往会比水晶本身的价值高出几倍甚至几百倍。
. The next layer is shaded in the determine. It has exactly the same aircraft-triangular construction; the atoms sit inside the holes shaped by the primary layer. The primary website layer has two equivalent sets of holes, nevertheless the atoms of the 2nd layer can occupy just one set. The 3rd layer, labeled C
正常的水晶在生长时，多可以发现和柱形尖端棱线平行的生长纹（expansion lines）。由于在地底、岩洞中的生长空间多狭窄，尤其在遇到地震时，或地壳变动时，甚至容易遭到其他矿石的挤压，常常会压迫产生不同的「晶面」。还有，当水晶还是在液态状的时候，常常也会包覆着其他的矿石、泥灰一起结晶成长，如金红石（稍后变成发晶）、火山泥灰（稍后变成幻影水晶）等等。所有的这些，都是「自然的一部分」，请不要视为「瑕疵」。
水晶饰品越来越受到人们的喜爱。中国、日本、韩国、美国等国家的人们还对水晶球情有独钟，喜欢将它们摆在家里或办公室里，认为水晶球有灵性，能保平安，带来财运。不过天然水晶不像看起来那么晶莹剔透，它也有瑕疵，我们在选购饰品的时候要注意。此外，我们还要掌握水晶的评价依据、选购方法，这样可以帮助我们在琳琅满目的水晶饰品中选到心仪的水晶。
crystal Alteration is variable: absent in lots of crystals, in Some others generating dense sericite aggregates which may show some recrystallization results to supply coarser-grained white mica. From your Cambridge English Corpus The tridymite crystals are rectangular or wedge-formed and are occasionally organized in aggregates. With the Cambridge English Corpus In addition, haloarchaeal cells have been embedded inside of salt crystals under laboratory conditions and subsequently analysed by light-weight microscopy. In the Cambridge English Corpus The white clouds (usually sparse) ended up also commonly thought to be remaining made up of little crystals of h2o ice, fairly like cirrus inside our atmosphere. From the Cambridge English Corpus These are found in evaporite salt lakes and might be trapped in salt crystals in the course of evaporation. In the Cambridge English Corpus Thus, the cells (organelles and membranes) are ruined mechanically by ice crystals, leading to Dying by way of cell lysis. Through the Cambridge English Corpus The crystals ended up Utilized in the very first or 2nd orders of reflection. In the Cambridge English Corpus Within our 8xperiments, the crystals were being cubes which has a base region of 8 e mm. Through the Cambridge English Corpus Vibration-assisted intermolecular hydrogen tunneling in photoreactive doped molecular crystals : outcome of temperature and stress.
