水晶表面坑洼的地方，有的深，有的浅，这是水晶在成长过程中自然形成的，并非是人为造成的损伤。缺陷位置本来包有其他矿物晶体，由于包裹体和水晶结合部位的结合力不强，当表面抛光时，矿体脱落，留下空位。这种缺陷在绿幽灵、钛晶、金发晶上都比较常见。
23Sometimes, however, the crystal sort of the silicate inclusions is observed to resemble additional closely The inner construction 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。
4Without a crystal ball, It is impossible to mention in which we'll be upcoming year.不用水晶球预卜未来，我们说不准明年处境如何呀。《牛津词典》
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。

These examples are from corpora and from resources on the web. Any views during the illustrations never symbolize the belief in the Cambridge Dictionary editors or of Cambridge College Push or its licensors.
Crystals glance one of a kind from many other rocks and minerals, but �?barring some Distinctive circumstances �?almost all minerals hide a crystalline framework underneath the surface.
如果水晶内部杂质中有传说中人物的造型，如佛、星座、生肖等价值可能要高于同等颜色和净度的水晶。
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：
Crystals with obvious flat faces are known as euhedral crystals, whilst People missing described faces are known as anhedral crystals. Crystals consisting of requested arrays of atoms that aren't usually periodic are termed quasicrystals.
There are 2 this kind of doable periodic preparations. In Just about every, the very first layer has the atoms packed right into a airplane-triangular lattice in which each and every atom has 6 immediate neighbours. Figure 2 shows this arrangement for your atoms labeled A
水晶的价值还与块体大小有关，同样的颜色和净度级别，块越大越难得。有时候质量级别虽然低一些，但块体够大，也可能价格高于高级别的小晶体
This Assessment chronicles around twenty years of study into making a genetic code for crystal engineering. Instead of directing Organic procedures, this code utilizes artificial varieties of DNA to programme the assembly of nanoparticles and microparticles into 1D, 2nd and 3D crystalline architectures, in which nearly each facet of the resultant structures could be systematically controlled. Inside this conceptual framework, the structural and purposeful advances are explained in an effort to outline the existing website standard of sophistication also to forecast foreseeable future directions in the platform.
