Not all crystals are equally crystalline. There in many cases are impurities, as well as the ionic & covalent amongst molecules can generate vastly diverse constructions from a similar product. An awesome example of this are diamonds and graphene.

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。
水碧：《山海经》中，水晶又被称作水碧： �?又南三百里，日耿山，无草木，多水碧 �?，郭璞注�?�?亦水玉类 ”。这种称谓常被文人所引用，晋代郭景纯《璞江赋》道�?�?鬼，水碧�?�?。水晶又有人称它叫玉瑛。《符瑞图》载�?美石似玉，水精谓之玉瑛也�?”
There are also a lot of supplies that resemble crystals but are literally polycrystals. Polycrystals type when microscopic crystals fuse jointly to variety a solid. These supplies tend not to include requested lattices.

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：
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。
水晶包裹体丰富多彩，从气体、液体到各种矿物质，甚至宝石，均可被包含于水晶内，各种包裹体所形成的景象更是变化万千。按照包裹体的内容，常把包裹体水晶分为一下八类：

Orthorhombic: These are generally rhombic prisms and dipyramids that resemble tetragons but with out square cross-sections.
Crystals are labeled generally speaking categories, such as insulators, metals, semiconductors, and molecular solids. A single crystal of the insulator is normally transparent and resembles a piece of glass. Metals are shiny Except if they've got rusted. Semiconductors are sometimes shiny and from time to time transparent but are never ever rusty. Quite a few crystals can be categorised as just one sort of good, while some have intermediate conduct. Cadmium sulfide (CdS) is often geared up in pure sort and is a superb insulator; when impurities are additional to cadmium sulfide, it gets to be an interesting semiconductor.
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。
