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 elementary idea in crystal structures will be the device cell. It is the smallest unit of volume that allows equivalent cells to generally be arranged collectively to occupy all obtainable Place. The geometrical foundation of all crystals is definitely the lattice. A lattice could be seen as an everyday and infinite arrangement of points or atoms, the place Each and every stage or atom has an identical encompassing surroundings.
天然水晶是不可再生资源，随着开发的深入，天然水晶存量已越来越少，为了可持续发展，东海县政府早就制定了保护本地资源，鼓励开发海外水晶资源的政策，但是，海外资源也越来越少，很多国家都提高了开采和出口天然水晶的门槛，进入东海市场的外国水晶价格连年暴涨，其中观赏水晶比普通水晶涨价更快。
The requested internal framework of huge crystals, like the fluorite and quartz revealed right here, is mirrored within their geometric shapes.
You will discover a number of crystals depending on geometric structures, crystal progress, and materials. There is usually arrangements of hexagonal carbon atoms or amethyst that makes hexagonal pyramid buildings.
Monoclinic �?Characterized by 3 unequal axes, two of which get more info intersect at an oblique angle, although the 3rd is perpendicular towards the aircraft of one other two.
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。
As being a hot Answer cools or simply a saturated Alternative evaporates, particles attract close more than enough for chemical bonds to sort. Crystals might also kind from deposition straight from the gasoline stage. Liquid crystals have particles oriented in an structured way, like strong crystals, yet can flow.
24I want to make my meaning crystal obvious.我想把我的意思解释得清清楚楚。《牛津词典》
看文化：水晶里面的包裹体象形，能与文化、宗教及历史有所牵连的话，价格往往会比水晶本身的价值高出几倍甚至几百倍。
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。
There are actually only some unique unit-cell styles, so a number of crystals share just one unit-mobile type. A vital attribute of a unit mobile is the number of atoms it has. The total number of atoms in the whole crystal may be the range in Every cell multiplied by the amount of unit cells. Copper and aluminum (Al) Every single have just one atom for every unit mobile, even though zinc (Zn) and sodium chloride have two. Most crystals have only some atoms for every device cell, but there are many exceptions. Crystals of polymers, one example is, have 1000s of atoms in Every device cell.
玉石纹理如果能形成美丽的花纹、图案，其价格就高，如玛瑙内红白相间的色带有规律地排列，形成缠丝玛瑙时，碧玉中的不均匀颜色形成一种风景图案时，材料的价值将提高。当水晶内包裹体形成美丽的图案时，如幽灵水晶、风景水晶，或者针状包裹体呈束状排列时，其价值都高于普通的水晶。图案越美观、越有意境越好。
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。
