看颜色：即使在同一种类的水晶中，它的不同部位的纹理、色泽也各式各有千秋。属于单色的，要色度均匀；在同一块水晶上有深浅的，则要求其色调纹路美观大方。
A basic notion in crystal buildings could be the device cell. It's the smallest device of volume that allows equivalent cells being organized jointly to occupy all readily available Place. The geometrical foundation of all crystals may be the lattice. A lattice may be seen as an everyday and infinite arrangement of factors or atoms, exactly where Every single position or atom has an identical bordering setting.
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。

当二氧化硅结晶完美时就是水晶；结晶不完美的就是石英：二氧化硅胶化脱水后就是玛瑙；二氧化硅含水的胶体凝固后就成为蛋白石；二氧化硅晶粒小于几微米时，就组成玉髓、燧石、次生石英岩。
30Three times went earlier, and I was astonished to see it yet again: every one of the openings had been sewed up by slender and white thread plus they looked such as ice crystal on Wintertime's branches while in the north.
Like a sizzling Remedy cools or possibly a saturated Remedy evaporates, particles draw close enough for chemical bonds to form. Crystals also can type from deposition straight from the gas phase. Liquid crystals have particles oriented within an arranged method, like strong crystals, but have the ability to flow.
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：

⑨、喷砂：立体感弱，较平整，无凹凸感，机器雕刻文字、图形等后进行效果处理。成本低制作快。
crystal Alteration is variable: absent in several crystals, in others producing dense sericite aggregates which can clearly show some recrystallization outcomes to generate coarser-grained white mica. In the Cambridge English Corpus get more info The tridymite crystals are rectangular or wedge-shaped and are occasionally organized in aggregates. Through the Cambridge English Corpus Additionally, haloarchaeal cells have been embedded within salt crystals less than laboratory ailments and subsequently analysed by light microscopy. Through the Cambridge English Corpus The white clouds (ordinarily sparse) were also greatly regarded as getting made up of tiny crystals of h2o ice, relatively like cirrus inside our ambiance. Through the Cambridge English Corpus They are really present in evaporite salt lakes and might be trapped in salt crystals for the duration of evaporation. From your Cambridge English Corpus Consequently, the cells (organelles and membranes) are wrecked mechanically by ice crystals, bringing about death by mobile lysis. Within the Cambridge English Corpus The crystals were used in the very first or 2nd orders of reflection. In the Cambridge English Corpus In our 8xperiments, the crystals have been cubes with a foundation space of 8 e mm. From the Cambridge English Corpus Vibration-assisted intermolecular hydrogen tunneling in photoreactive doped molecular crystals : influence of temperature and tension.
