This concept applies equally in one, two, and a few-dimensional Areas. The complete crystal lattice may be constructed by regularly reproducing the pattern on the device cell in all Instructions.
杂质、裂纹越少越好。质地好的水晶制品，应看不到星点状、云雾状和絮状分布的气液包裹体或组成玉石的颗粒。有裂纹、斑点，则属于次品。
景观水晶，就是包裹体组成各种造型特异的水晶，有的似山水，有的似人物，有些像文字，有些像动物，植物，器物等等。
Encyclopaedia Britannica's editors oversee matter areas in which they may have comprehensive know-how, whether or not from yrs of working experience gained by focusing on that written content or by means of study for a sophisticated diploma. They publish new information and verify and edit content acquired from contributors.
C2 [ U ] transparent glass of incredibly superior quality, typically with its area Lower into sensitive patterns:
Lattices might have 1 lattice issue for each cell or multiple, yielding a complete of fourteen Bravais crystal lattice varieties. Bravais lattices, named for physicist and crystallographer Auguste Bravais, describe the 3-dimensional array made by a set of discrete points.
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。
②固体包裹体：指呈固态相存在包裹体，多因岩浆、热液、变质作用等形成的早期结晶物被水晶捕获而形成。
Quite a few crystals behave like butter in that they're challenging at reduced temperatures but tender at bigger temperatures. These are referred to as solids in any way temperatures beneath their melting level. A probable definition of a sound is an object that retains its click here condition if remaining undisturbed. The pertinent problem is just how long the object keeps its shape. A hugely viscous fluid retains its form for an hour or so but not a yr. A sound will have to continue to keep its condition extended than that.
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。
. The next layer is shaded in the determine. It's got the same airplane-triangular composition; the atoms sit from the holes fashioned by the first layer. The 1st layer has two equal sets of holes, though the atoms of the 2nd layer can occupy just one set. The 3rd layer, labeled C
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。
⑤、打孔：是在水晶成品未完成前，根据其所需打孔之尺寸及位置，以钻头加工，如制表件、笔筒、瓶孔等。
对于紫水晶黄水晶这样的单色水晶，通常要观察它的二色性，即使是最顶级的紫水晶黄水晶也是有色差的，通过这个方法可以鉴别是否加色。
