17These rings are indicative from the crystal composition of nickel and can be spelled out only by invoking wavelike Homes of light.这些光圈表明了了镍的晶体结构，而且只能通过光线中波的特征来解释。
23Sometimes, nonetheless, the crystal type of the silicate inclusions is noticed to resemble more carefully The inner composition of diamond than that of other silicate minerals.然而，有时观察到硅酸盐包裹体的晶体形态比其他硅酸盐矿物更接近金刚石的内部结构。
人造水晶分为熔炼水晶与养殖晶：据水晶专家汪毅的阐述，随着水晶的价值提高，喜欢的人增多，水晶也引起了作伪者的兴趣，现阶段中国水晶市场常见的造假方法为：
养殖晶：养殖晶是指，用天然水晶做种子，然后赋予天然水晶生长的高压条件，养殖器中有富含二氧化硅的分子。然后二氧化硅分子围绕天然水晶种生长，这样的水晶成分（分子式）与天然水晶是一摸一样的，唯一有差别的是，这样的水晶磁场作用没有天然水晶强。
这种水晶观赏石特指水晶晶簇，它是众多单晶体集中生长在一起的晶体组合。晶簇以其晶莹剔透、独特造型而享誉水晶赏石界。
你们都知道，拿起一个水晶棱镜，让一束阳光通过它，就会得到一个光谱，看起来就像一条连续的彩虹色带。
水晶内部有多种矿物包裹体，形成的各种景观可以肉眼观测，这样的水晶就是包裹体水晶观赏石。由于水晶本身就是宝石，因此人们称誉包裹体水晶为“宝石级的观赏石”。包裹体水晶观赏石都具有独特性，具有极高欣赏和收藏价值。
Hexagonal �?Characterized by four axes, 3 of that happen to be equal in length and intersect at one hundred twenty levels, by using a fourth axis perpendicular to the other a few.
水晶是有成色等级之分，影响水晶价位的因素很多，不像钻石以4C就可以判定，所以大家要多听多看多比较才能真正辨别出来。一般的标准是水晶石越大越好，越透越好，颜色越娇嫩越好，形状越典型越好。不过最重要还是自己喜欢，而选购时辨识真伪的方法大致有下列几种：
A crystal system refers to the classification of crystals based on the geometric arrangement and symmetry of their lattice buildings. You can find seven major crystal devices:
One crystals of metals are tender and malleable, while polycrystalline metals are more durable and stronger and tend to be more helpful industrially. Most polycrystalline resources is often created into big single crystals soon after extended warmth cure. In the past blacksmiths would heat a bit of metal to really make it malleable: warmth helps make some grains expand significant by incorporating lesser kinds. The smiths would bend the softened metal into shape after which pound it awhile; the pounding would help it become polycrystalline again, expanding its energy.

玉石纹理如果能形成美丽的花纹、图案，其价格就高，如玛瑙内红白相间的色带有规律地排列，形成缠丝玛瑙时，碧玉中的不均匀颜色形成一种风景图案时，材料的价值将提高。当水晶内包裹体形成美丽的图案时，如幽灵水晶、风景水晶，或者针状包裹体呈束状排列时，其价值都高于普通的水晶。图案越美观、越有意境越好。
crystal Alteration is variable: absent in many crystals, in Some others manufacturing dense sericite aggregates which may clearly show some recrystallization results to create coarser-grained white mica. From your Cambridge English Corpus The tridymite crystals are rectangular or wedge-formed and are sometimes organized in aggregates. From here the Cambridge English Corpus Furthermore, haloarchaeal cells were embedded in salt crystals underneath laboratory circumstances and subsequently analysed by mild microscopy. In the Cambridge English Corpus The white clouds (typically sparse) were being also widely regarded as staying made up of little crystals of drinking water ice, rather like cirrus inside our atmosphere. Within the Cambridge English Corpus They may be found in evaporite salt lakes and will be trapped in salt crystals in the course of evaporation. In the Cambridge English Corpus Thus, the cells (organelles and membranes) are wrecked mechanically by ice crystals, leading to Demise by means of mobile lysis. From your Cambridge English Corpus The crystals have been Utilized in the very first or second orders of reflection. Within the Cambridge English Corpus Inside our 8xperiments, the crystals have been cubes which has a base location of eight e mm. In the Cambridge English Corpus Vibration-assisted intermolecular hydrogen tunneling in photoreactive doped molecular crystals : influence of temperature and pressure.
