水晶表面坑洼的地方，有的深，有的浅，这是水晶在成长过程中自然形成的，并非是人为造成的损伤。缺陷位置本来包有其他矿物晶体，由于包裹体和水晶结合部位的结合力不强，当表面抛光时，矿体脱落，留下空位。这种缺陷在绿幽灵、钛晶、金发晶上都比较常见。

Bismuth (Bi) appears being a metal, but the number of electrons accessible for electrical conduction is comparable to that of semiconductors. In reality, bismuth is referred to as a semimetal. Molecular solids usually are crystals shaped from molecules or polymers. They may be insulating, semiconducting, or metallic, depending upon the sort of molecules during the crystal. New molecules are continually being synthesized, and a lot of are made into crystals. The number of unique crystals is big.

水晶文化历史悠久，古人曾赋予它一串极富美感的雅称：水玉、水精、水碧、石英等。

Fig. three: A library of lattice symmetries is usually accessed by changing the particle Main and DNA shell.

There are many alternative crystals dependant upon geometric structures, crystal progress, and content. There can be arrangements of hexagonal carbon atoms or amethyst that makes hexagonal pyramid buildings.

发晶，包括钛晶，铜顺发，绿发晶，黑发晶，银发晶，杂色发晶，其中钛晶最珍贵，少数钛晶价值可比钻石，红宝石和蓝宝石以及祖母绿。

光泽：玻璃光泽。断口处为油脂光泽。光泽，指宝石表面对光线反射的一种光学性质。观察水晶的光泽，可用手握着它，以灯光或窗户投进来的光线看表面反射，透明水晶亮度与光泽强弱有关。

损伤是指水晶由于加工或不小心摔掉、碰撞等原因，人为造成的损坏。它可以是破口，也可以是凹坑等。

第三种是“皮景”，因某些其他的矿物与水晶体共生，或由于其他的物质侵蚀而依附于水晶表面，或者是水晶受自然环境的影响，在水晶表面出现蚀象，形成了一些景象或图案，这种景观存在于水晶表面。

晶体 Silicon crystals grown inside of a laboratory transform light into electrical Strength. 在实验室中长成的硅晶体可将光线转变为电能。

被主体水晶所捕获的包裹体。原生包裹体通常为固相，形态较规则。水晶中典型的原成包裹体有金红石、电气石、黄铁矿等，也会见到岩石碎屑或集合体。

Crystals are classified normally groups, for click here example insulators, metals, semiconductors, and molecular solids. A single crystal of the insulator is normally clear and resembles a piece of glass. Metals are shiny Until they may have rusted. Semiconductors are occasionally shiny and in some cases transparent but are in no way rusty. Lots of crystals can be classified as an individual form of sound, while others have intermediate behaviour. Cadmium sulfide (CdS) is usually geared up in pure kind and is a wonderful insulator; when impurities are added to cadmium sulfide, it will become a fascinating semiconductor.

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。
