天然的水晶一般都会有絮状（绵绺），也就是大家俗称的瑕疵，这是液体水落石出和二氧化碳的小孔穴，而人工合成的水晶就不会有这样的特征。
Bismuth (Bi) appears to generally be a steel, but the number of electrons accessible for electrical conduction is similar to that of semiconductors. The truth is, bismuth is named a semimetal. Molecular solids are frequently crystals fashioned from molecules or polymers. They are often insulating, semiconducting, or metallic, with regards to the type of molecules while in the crystal. New molecules are repeatedly getting synthesized, and plenty of are made into crystals. The number of distinctive crystals is enormous.
晶及其石英岩类玉石是中低档宝玉石，虽比不上钻石、红蓝宝石的高贵，但在加工中如果构思巧妙而且加工精细，同样具有很高的价值。如中国传统的玛瑙“虾盘”、“龙盘”、“水漫金山�?水胆玛瑙摆件)都被誉为国家级宝玉石。
水碧：《山海经》中，水晶又被称作水碧： �?又南三百里，日耿山，无草木，多水碧 �?，郭璞注�?�?亦水玉类 ”。这种称谓常被文人所引用，晋代郭景纯《璞江赋》道�?�?鬼，水碧�?�?。水晶又有人称它叫玉瑛。《符瑞图》载�?美石似玉，水精谓之玉瑛也�?”
There's also a lot of resources that resemble crystals but are literally polycrystals. Polycrystals sort when microscopic crystals fuse together to form a solid. These products usually do not consist of requested lattices.
Not all crystals sort in h2o, but nearly all crystals type the same way, atoms come together and turn into get more info a uniformed cluster. The method can take as very little as a few days to perhaps a thousand many years. Pure crystals that come from the Earth type the exact same way.
⑩、雷射内雕：以计算机辅助激光设备在水晶对象中进行三维图案的成型，艺术效果好，可以任意表达各类图案，图形，达到逼真效果
Ionic Crystals: Electrostatic forces kind ionic bonds. A typical example is really a halite or salt crystal.
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：
晶体 Silicon crystals developed in the laboratory convert light into electrical Electricity. 在实验室中长成的硅晶体可将光线转变为电能。
say cheese a thing that a person who is taking a photograph of you tells you to convey so that the mouth makes the shape of the smile
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。
玉石纹理如果能形成美丽的花纹、图案，其价格就高，如玛瑙内红白相间的色带有规律地排列，形成缠丝玛瑙时，碧玉中的不均匀颜色形成一种风景图案时，材料的价值将提高。当水晶内包裹体形成美丽的图案时，如幽灵水晶、风景水晶，或者针状包裹体呈束状排列时，其价值都高于普通的水晶。图案越美观、越有意境越好。
Binary crystals are located in several structures. Some pairs of elements variety more than one framework. At area temperature, cadmium sulfide may perhaps crystallize either from the zinc blende or wurtzite structure. Alumina also has two attainable structures at space temperature, α-alumina (corundum) and β-alumina. Other binary crystals show different constructions at distinct temperatures. One of the most advanced crystals are People of silicon dioxide (SiO2), which has 7 different buildings at many temperatures and pressures; the commonest of such buildings is quartz.
