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。
Bismuth (Bi) seems to become a steel, but the quantity of electrons available for electrical conduction is analogous to that of semiconductors. In actual fact, bismuth is named a semimetal. Molecular solids usually are crystals formed from molecules or polymers. They are often insulating, semiconducting, or metallic, based on the form of molecules inside the crystal. New molecules are repeatedly currently being synthesized, and a lot of are made into crystals. The amount of distinctive crystals is gigantic.
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。

水胆水晶，包括气态，液态，固态，有时候可以同时多态并存，无色居多，个别情况下可见红色，绿色，黄色，蓝色，黑色等。

时尚的收藏爱好者喜欢收藏天然水晶，却常常因为在市场上面对大量的合成水晶看走了眼。市面上的水晶：

Solids which have shorter-range order but absence lengthy-variety order are known as amorphous. Just about any product is usually created amorphous by rapid solidification from the soften (molten condition). This situation is unstable, and the strong here will crystallize in time. In case the timescale for crystallization is yrs, then the amorphous condition appears stable.
There are two these kinds of possible periodic arrangements. In Every, the initial layer has the atoms packed into a aircraft-triangular lattice in which each and every atom has 6 quick neighbours. Determine two shows this arrangement for that atoms labeled A
正常的水晶在生长时，多可以发现和柱形尖端棱线平行的生长纹（development traces）。由于在地底、岩洞中的生长空间多狭窄，尤其在遇到地震时，或地壳变动时，甚至容易遭到其他矿石的挤压，常常会压迫产生不同的「晶面」。还有，当水晶还是在液态状的时候，常常也会包覆着其他的矿石、泥灰一起结晶成长，如金红石（稍后变成发晶）、火山泥灰（稍后变成幻影水晶）等等。所有的这些，都是「自然的一部分」，请不要视为「瑕疵」。
The framework on the sodium atoms alone, or the chlorine atoms by yourself, is fcc and defines the device mobile. The sodium chloride structure So is created up of two interpenetrating fcc lattices. The cesium chloride lattice (Figure 3A) is predicated about the bcc structure; each individual other atom is cesium or chlorine. In such a case, the unit mobile is actually a dice. The third critical structure for AB
水晶观赏石在形态、质地、内部特征等方面往往十分奇异。大自然有无限风光，都可以在包裹体水晶种找到缩影。
