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。
③、粗抛光：是将模具压出之毛胚，以金刚石盘直接磨出成品之刻线。④、细抛光：在粗抛光之后，以抛光粉来磨成品至晶莹剔透为止。
These innovations include things like unique structures with programmable lattice symmetries and very well-defined crystal practices, responsive components that leverage the intrinsic properties of nucleic acids to govern structures on desire, nanoparticle superlattices developed epitaxially from surfaces and colloidal crystals that supply insights into gentle–subject interactions. Looking ahead, we obstacle the Local community to leverage the amazing structural control afforded by crystal engineering with DNA to synthesize classes of functional supplies that force outside of what is attainable with naturally developing crystalline products or those produced by extra regular techniques.
Most reliable elements present in nature exist in polycrystalline variety rather then as an individual crystal. They are actually composed of a lot of grains (compact crystals) packed collectively to fill all space. Each personal grain has a unique orientation than its neighbours. Even though lengthy-selection order exists within just one particular grain, within the boundary amongst grains, the ordering variations direction. A normal piece of iron or copper (Cu) is polycrystalline.
根据美国已经了解的情况，统计局的专家和其他人口统计学家在他们的视野中提供了一个不可抗拒的水晶球。
Lattices may have one particular lattice place per cell or more than one, yielding a total of fourteen Bravais crystal lattice kinds. Bravais lattices, named for physicist and crystallographer Auguste Bravais, describe the three-dimensional array produced by a set of discrete factors.
水晶内部有多种矿物包裹体，形成的各种景观可以肉眼观测，这样的水晶就是包裹体水晶观赏石。由于水晶本身就是宝石，因此人们称誉包裹体水晶为“宝石级的观赏石”。包裹体水晶观赏石都具有独特性，具有极高欣赏和收藏价值。
市场上有很多人把熔炼水晶也叫做合成水晶，那是不准确的，一般都是以水晶废料为原料在高温高压下熔炼出来的，而不是结晶成的，不具备水晶的晶体特性，所以不能把熔炼水晶与合成水晶混为一谈；但是熔炼水晶耐高温，用优质二氧化硅熔炼成的熔炼水晶可以做成实用产品比如水晶杯、烤盘、茶具等，实际上一代伟人毛泽东主席的水晶棺就是选用东海优质水晶熔炼而成的。
Metallic Crystals: Metals typically type metallic crystals, more info where by several of the valence electrons are no cost to maneuver through the lattice. Iron, such as, can form distinctive metallic crystals.
广义的包裹体是指宝石内部含有的与主晶宝石化学成分、物理性质等不同的物质。

Crystals are not only renowned for his or her Actual physical visual appeal, but diverse crystals of various products and formations can result in an unlimited assortment of works by using and Bodily Attributes.
《古今小说·李公子救蛇获称心》：“器皿皆是玻璃、水晶、琥珀、玛瑙为之，曲尽巧妙，非人间所有。”
⑥白色的包裹体有蚀变的绿泥石、云母、愈合裂隙、水晶、方解石、透闪石等。
