These crystals were being fashioned over 1,000,000 yrs back inside the Earth's crust. They happen in the event the liquid from the Earth consolidates along with the temperature chills. Other crystals form in the event the liquid will make its way from the clefts and dispense minerals in to the clefts.
水晶原石观赏石充分体现了天然水晶的本质，经过抛光的水晶原石观赏石，玲珑剔透、晶莹璀璨，独具匠心的设计，恰到好处地显露出水晶的魅力。如果您想单纯的欣赏水晶，水晶原石观赏石是你的不二之选，给人一种返璞归真的感觉。
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。
The ordered interior construction of large crystals, just like the fluorite and quartz shown here, is reflected within their geometric styles.
You can also find several products that resemble crystals but are actually polycrystals. Polycrystals form when microscopic crystals fuse together to kind a stable. These components do not include purchased lattices.
Not all crystals kind in h2o, but nearly all crystals kind a similar way, atoms come collectively and turn into a uniformed cluster. The method normally takes as minor as a couple of days to possibly a thousand several years. Normal crystals that originate from the Earth type the exact same way.
石英：《广雅》称水晶叫石英，色白如莹者又叫白。为附的异形字。司马相如《子虚赋》就�?�?雌黄�?�?之句。苏林解释：�?�?，白石英�?”。
You will find there's identical directive about crystal glass which differentiates between total direct crystal, guide crystal and crystal.
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。

用手去触摸水晶，天然水晶通常温度要比人造水晶的要凉的多；用眼观察，天然水晶通常有棉絮状的包裹体，这个是人造水晶所没有的。
隐晶类水晶外观是一块块的，不是成六角水晶簇状，但他们却也是属六方晶系的。但我们不能以肉眼观察到他们的六角形结晶，因为结晶的体积极为细小，需以显微镜协助下才能看到六角开结晶。而此类水晶非常平滑，因为结晶之间有“水化硅石”填补，玛瑙便属于此类。
Crystals are classified on the whole groups, like insulators, metals, semiconductors, and molecular solids. Only one crystal of an insulator is usually transparent and resembles a piece of glass. Metals are shiny Except they've rusted. Semiconductors are occasionally shiny and from time to time clear but are in no way rusty. Numerous crystals may be categorized as a single type of strong, while others have intermediate conduct. Cadmium sulfide (CdS) may be well prepared in pure type and is an excellent insulator; when impurities are added to cadmium sulfide, it turns into a fascinating semiconductor.
21You all know the way if you take a crystal prism and pass a beam of daylight as a result of it, you get a spectrum, which appears like a continual Crystal band of rainbow colours.
