A sound is crystalline if it's prolonged-array get. When the positions of the atom and its neighbours are known at one point, the put of every atom is understood precisely through the crystal. Most liquids deficiency lengthy-array purchase, Whilst a lot of have limited-vary get. Shorter selection is described as the primary- or second-closest neighbours of an atom. In lots of liquids the initial-neighbour atoms are arranged in exactly the same structure as in the corresponding solid phase.
Yet another pleasurable, and delicious, experiment should be to sort massive crystals working with sugar. By heating sugar with drinking water and afterwards allowing this Alternative evaporate on sticks, it is possible to form rock candy from sugar crystals!
看做工：水晶制品加工过程分为两种，即磨工和雕工。如水晶项链、手链、耳环等属于研磨品；观音像、内画鼻烟壶等属于雕刻品。
The requested inside structure of large crystals, much like the fluorite and quartz shown here, is mirrored within their geometric shapes.
Fig. four: Creating blocks with diverse styles and surface chemistries direct the formation of distinct crystal symmetries.
Lattices might have one particular lattice level for every cell or more than one, yielding a total of fourteen Bravais crystal lattice styles. Bravais lattices, named for physicist and crystallographer Auguste Bravais, describe the a few-dimensional array made by a set of discrete factors.
⑩、雷射内雕：以计算机辅助激光设备在水晶对象中进行三维图案的成型，艺术效果好，可以任意表达各类图案，图形，达到逼真效果

包裹体常见有固相、固液气三相组合、空洞以及双晶、色带等。水晶中典型的同生包裹体有自形的锐钛矿、气液两相包体等。

天然性是水晶观赏石的基本特性。通常整体造型水晶矿物不饰雕琢就具备很高的观赏价值，但是包裹体水晶观赏石经常需要适当打磨抛光，这样更方便观赏水晶内部的包裹体。
Crystal Lattices You will discover seven programs of crystal constructions, which happen to be also referred to as lattices or House lattices:
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。
矿物成分：针铁矿、赤铁矿、金红石、磁铁矿、电气石、石榴石、云母、绿泥石等形成了包裹体水晶，如发晶、钛晶、绿幽灵等，发晶中则含有肉眼可见的似头发状的针状矿物的包裹体形成。含锰和铁者称紫水晶；含铁�?；呈金黄色或柠檬�?)称黄水晶；含锰和钛呈玫瑰色者称蔷薇石英，即粉水晶；烟色者称烟水晶；褐色者称茶晶；黑色透明者称为墨晶。
