Calcite crystals are frequently Utilized in optical machines, and also the graphite in pencil direct are sheets of crystals that primarily break aside layer by layer to jot down. Silica can variety silicate crystals which might be the basis for quartz, mica, olivine, and all kinds of other crystals and minerals.
23Sometimes, however, the crystal kind of the silicate inclusions is observed to resemble additional intently the internal structure 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。
10This is the silicon chip—a little bit chip of silicon crystal.这是硅芯片——一个硅晶体的小芯片。
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。
2She was sporting a strand of crystal beads.她戴着一串水晶珠子。《柯林斯英汉双解大词典》
结晶�?When sea h2o is permitted to evaporate, salt crystals are deposited. 海水蒸发后，盐的结晶体就沉淀下来。
根据包裹体和主晶宝石之间形成的先后关系可将水晶的包裹体划分以下三种类�?
The elements are observed in many different crystal packing preparations. The most typical lattice constructions for metals are All those attained by stacking the atomic spheres into the most compact arrangement.
Metallic Crystals: Metals normally variety metallic crystals, the place some of the valence electrons are no cost to move all over the lattice. Iron, by way of example, can variety different metallic crystals.
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。
隐晶类水晶外观是一块块的，不是成六角水晶簇状，但他们却也是属六方晶系的。但我们不能以肉眼观察到他们的六角形结晶，因为结晶的体积极为细小，需以显微镜协助下才能看到六角开结晶。而此类水晶非常平滑，因为结晶之间有“水化硅石”填补，玛瑙便属于此类。
水玉：中国最古老的称法叫水玉，意谓似水之玉，又说是 �?千年之冰所�?�?。唐代诗人温庭筠《题李处士幽居》写道：�?水玉簪头白角巾，瑶琴寂历拂轻�?”。水玉一词最早频繁出于《山海经》：�?又东三百里，日堂庭之�?…�?多水�?”；�?丹山出焉，东南流注于洛水，其中多水玉 ”；�?逐水出焉，北流注于渭，其中多水玉 ”。司马相如《上林赋》曰�?�?水玉磊河 �?。水晶得名水玉，古人是看�?�?其莹如水，其坚如�?�?的质地。
