These crystals were formed more than one million several years ago Within the Earth's crust. They occur in the event the liquid from the Earth consolidates as well as the temperature chills. Other crystals variety when the liquid would make its way throughout the clefts and dispense minerals in to the clefts.
无色水晶以晶莹美丽、洁净透明着称。衡量无色水晶主要看它的纯度，越纯、越透明越好。干净的、无瑕疵的、杂质少的价值就高。无色的水晶如果很脏，就没有利用价值。
人造水晶分为熔炼水晶与养殖晶：据水晶专家汪毅的阐述，随着水晶的价值提高，喜欢的人增多，水晶也引起了作伪者的兴趣，现阶段中国水晶市场常见的造假方法为：
Most stable resources found in mother nature exist in polycrystalline kind as opposed to as only one crystal. They are literally composed of many grains (modest crystals) packed together to fill all Place. Every single person grain has a distinct orientation than its neighbours. Although very long-variety get exists in one grain, in the boundary between grains, the ordering adjustments path. A normal bit of iron or copper (Cu) is polycrystalline.

水晶原石观赏石，从字面意义理解：观赏水晶石的原貌，即经过抛光去皮后的包裹体水晶和原色水晶，不需雕刻不求象形就具有非常高的观赏价值和收藏价值。此类水晶观赏石对质地要求非常之高，水晶晶体通透干净，颜色艳丽，意境鲜明深刻的价值就高，它的价值特点就好比钻石，实实在在石头本身的价值。
For a warm Option cools or a saturated Answer evaporates, particles draw close plenty of for chemical bonds to kind. Crystals might also kind from deposition directly from the fuel stage. Liquid crystals have particles oriented in an structured method, like good crystals, but can stream.
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：
Solids that have brief-assortment order but absence very long-vary get are termed amorphous. Pretty much any content could be produced amorphous by speedy solidification in the soften (molten point out). This affliction is unstable, and the good will crystallize in time. If the timescale for crystallization is decades, then the amorphous state appears stable.
16I opened the box and observed a bit of crystal snowflake along with a greeting card with "Delighted Birthday" within the blank paper.我打开盒子并看见在白纸中有一片水晶雪花和一张写着“生日快乐”的贺卡。
Crystallography could be the study of crystals, and it specials with almost everything from perfect geometric designs to seemingly random conglomerations of particles and minerals.
This Review chronicles about twenty years of research into creating a genetic code for crystal engineering. As an alternative to directing Organic processes, this code works by using artificial forms of DNA to programme the more info assembly of nanoparticles and microparticles into 1D, 2D and 3D crystalline architectures, in which just about each and every element of the resultant structures could be systematically managed. Within just this conceptual framework, the structural and functional innovations are described in order to outline the present degree of sophistication also to forecast long run Instructions in the System.
21You all know how any time you take a crystal prism and move a beam of sunlight by it, you receive a spectrum, which appears like a continuous band of rainbow shades.
