其它描述：《庶物异名疏》中说： �?水精出大秦国，一名黎�?�?。结晶完整的水晶晶体，就如参差交错的马齿，所以人们又叫它马牙石。先民们最早用它研磨成眼镜片，因而送它一个眼镜石的绰号。水晶有通称，也有俗称。广州一带称水晶叫晶玉，又名鱼脑冻；江苏东海县山民发现水晶会 �?窜火�?�?，于是给它起个放光石的俗名。世间一物多名，不足为奇，而像水晶拥有这么多的别称，实不多见。瞧，从水玉、水碧、白玉、玉瑛、水精石英、黎难、晶玉到菩萨石、马牙石、眼镜石、放光石、千年冰、高山冻、鱼脑冻等等，简直构成一部奇石鉴赏史。
A essential thought in crystal constructions would be the unit cell. It is the smallest unit of volume which allows similar cells to generally be organized with each other to occupy all readily available Room. The geometrical basis of all crystals would be the lattice. A lattice is often seen as an everyday and infinite arrangement of points or atoms, in which Every stage or atom has The same bordering atmosphere.
4Without a crystal ball, It can be unattainable to state wherever we are going to be up coming 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》
We have written about over three hundred stones while in the mineral kingdom! Read about Every single stone's unique origin, heritage, and energies under.
《全唐诗》卷七八五载《白雪歌》：“鸟啄冰潭玉镜开，风敲檐溜水晶折。”
Find out how the shape in the crystals establish the various minerals into familiesMinerals crystallize In accordance with certainly one of 7 motifs, often known as crystal systems.
解理：无解理。所谓解理是指矿物被打击时，沿一定方向有规则地裂开形成光滑平面的性质。根据解理的程度可以分为五类：极完全解理、完全解理、中等解理、不完全解理和无解理，水晶属于无解理。

Among the binary crystals, the best constructions to visualize are These with equivalent numbers of The 2 kinds of atoms. The structure of sodium chloride relies on the cube. To assemble the lattice, the sodium and chlorine atoms are put on alternate corners of a dice, plus the construction is repeated (Figure 3B).
Crystals with noticeable flat faces are named euhedral crystals, while Individuals missing outlined faces are termed anhedral crystals. Crystals consisting of ordered arrays of atoms that are not usually periodic are termed quasicrystals.
看孔眼：对于缀穿水晶制品（如项链、手链、佛珠），要看孔眼是否平直，孔的粗细是否均匀，有无细小裂纹。孔壁必须清澈透明，无“白痕”。
The sodium chloride crystal lattice is characterized through the near packing with the good here sodium ions and negative chloride ions. Every single sodium ion is surrounded by six chloride ions, and each chloride ion is surrounded by six sodium ions, developing a remarkably steady and symmetrical construction.
The construction from the sodium atoms on your own, or the chlorine atoms alone, is fcc and defines the unit mobile. The sodium chloride structure Therefore is created up of two interpenetrating fcc lattices. The cesium chloride lattice (Figure 3A) relies around the bcc framework; just about every other atom is cesium or chlorine. In this instance, the device mobile is usually a cube. The 3rd significant construction for AB
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。
