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。
杂质、裂纹越少越好。质地好的水晶制品，应看不到星点状、云雾状和絮状分布的气液包裹体或组成玉石的颗粒。有裂纹、斑点，则属于次品。
发晶的价值取决于发的颜色、罕见性及大小，一般是发色鲜艳、块度大的价格高。水胆水晶的价值主要取决于水胆及晶体的大小、透明度的高低。如果水胆较大并有一定形态，便可加工成较为珍贵的工艺品。另外水胆中的水也有一定的科学研究价值，通过它们可了解几百万年前地球上水的成分及变化。
If you want to see how crystals are shaped, you can perform a little task within your extremely possess kitchen area and find out the formation with the crystals arise with your individual eyes . This can be completed by Placing a little amount of table salt into some typical faucet water, wait 24 several hours, and you may see nice cubed formations. This happens since the drinking water is evaporating, which causes the atoms that make up the salt (the mineral) as well as the drinking water to come back nearer jointly.
How Crystals Kind The whole process of forming a crystal is termed crystallization. Crystallization typically occurs click here each time a solid crystal grows from the liquid or solution.

根据包裹体和主晶宝石之间形成的先后关系可将水晶的包裹体划分以下三种类�?
The weather are located in many different crystal packing arrangements. The most typical lattice structures for metals are People received by stacking the atomic spheres into by far the most compact arrangement.
水晶常以晶簇、晶洞形式产出，其中水晶洞一般存在于由火山喷发而形成的巨厚熔岩流层的火成岩与玄武岩中。火山喷发时所含的气体或热水溶蚀等作用导致岩层中出现大量的孔隙，当富含硅质矿物的流体进入较薄的熔岩孔隙中，且温、压条件合适时将结晶沉淀出水晶等矿物。
Solids which have quick-range order but lack lengthy-assortment purchase are referred to as amorphous. Almost any substance is usually built amorphous by immediate solidification from the melt (molten state). This issue is unstable, and also the solid will crystallize in time. If the timescale for crystallization is decades, then the amorphous point out seems stable.
15The trick to an excellent thermoelectric product is really a crystal construction by which electrons can flow freely.制造一种好的热电材料的关键是，需要一种电子可以自由流动的晶体结构。
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（expansion strains）。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」。
《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。”
水晶观赏石是天然水晶中最具代表的作品，具有其他宝石都不具备的观赏性。不论是玉石翡翠还是都要经过雕琢后次能体现他的价值，而水晶观赏石只需要将表面进行抛光，即展现出晶体内所包裹的物质，直接欣赏原汁原味的水晶石。
