诗中“胜美玉”，“过冰清”，写出水晶的质地美，而“亦欲应时明”则描绘出水晶充满灵性的动态美，耐人寻味。罗维是有独特眼光，懂得水晶真谛，第一个称赞水晶超过美玉的伟大诗人。他的认识已被千年之后的科学理论所证实；以水晶为直接吟咏对象的诗篇还有：
⒉棉、云雾或渣状包裹体、杂质在透明水晶内部有雾蒙蒙的现象或是感觉里面像有棉絮状、渣状物质一样的包裹体，这些包裹体的存在，影响水晶的整体美观。还有的水晶内局部含有黑斑或其他颜色的斑状物质，与水晶整体不协调，被视为水晶的杂质，有这种杂质的水晶是次品。
Chemical Bonds The categories of chemical bonds fashioned amongst atoms or groups of atoms in crystals depend upon their dimension and electronegativity. You will discover 4 classes of crystals as grouped by their bonding:
第一种是“全包裹体”，在水晶结晶的时候把这些物质包裹在晶体里面，这类包裹体所形成的各种景象，大多保持了水晶结晶时的原状，也就是说保存了几亿年的原状，极少受到自然环境的影响。
How Crystals Form The whole process of forming a crystal known as crystallization. Crystallization generally happens every time a strong crystal grows from the liquid or Resolution.
Not all crystals form in drinking water, but almost all crystals variety exactly the same way, atoms come collectively and turn into a uniformed cluster. The process may take as small as a few days to probably a thousand many years. Pure crystals that come from the Earth form a similar way.
Incorporate to phrase checklist Add to term list [ C/U ] clear rock that appears like ice, or a bit of it
To be a scorching Resolution cools or even a saturated Resolution evaporates, particles attract shut ample for chemical bonds to variety. Crystals might also type from deposition straight from the gasoline phase. Liquid crystals possess particles oriented within an arranged method, like reliable crystals, however are able to circulation.
水晶是有成色等级之分，影响水晶价位的因素很多，不像钻石以4C就可以判定，所以大家要多听多看多比较才能真正辨别出来。一般的标准是水晶石越大越好，越透越好，颜色越娇嫩越好，形状越典型越好。不过最重要还是自己喜欢，而选购时辨识真伪的方法大致有下列几种：
A crystal method Crystal refers to the classification of crystals based on the geometric arrangement and symmetry in their lattice structures. You'll find seven principal crystal programs:
天然性是水晶观赏石的基本特性。通常整体造型水晶矿物不饰雕琢就具备很高的观赏价值，但是包裹体水晶观赏石经常需要适当打磨抛光，这样更方便观赏水晶内部的包裹体。
The sodium chloride crystal lattice is characterized from the near packing of the beneficial sodium ions and negative chloride ions. Each sodium ion is surrounded by 6 chloride ions, and each chloride ion is surrounded by 6 sodium ions, making a remarkably steady and symmetrical composition.
⑦双色水晶：一种紫色和黄色共存一体的水晶，紫色、黄色之间界限较明显，分别占据晶块的一部分。
This crystal composition is answerable for the one of a kind physical and chemical Homes of sodium chloride, which include its substantial melting place, electrical conductivity, and skill to type ionic bonds simply.
