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：

一般而言，紫晶和黄晶是水晶中价值较高的品种。两者进一步的分级是据其颜色的深浅，颜色较深的为A级，稍浅的为B级。一般颜色较深的价格高，但要以不深暗为标准。颜色包括两种，一种是水晶本身的颜色，另一种是内部包裹体的颜色。水晶本身的颜色要艳丽、纯正，分布要均匀，不能太深或太浅，如澳州玉、蓝玉髓、紫晶、黄水晶，其价格就高。无色的水晶内含包裹体的颜色艳丽，其价格也高，如钛晶、绿幽灵、红兔毛。紫水晶一般以稍有云状物、颜色深紫、晶体通透的为上品。
Most good resources found in mother nature exist in polycrystalline variety in lieu of as just one crystal. They are literally composed of many grains (little crystals) packed collectively to fill all House. Every specific grain has a unique orientation than its neighbours. Even though very long-assortment get exists inside just one grain, for the boundary among grains, the buying variations way. A typical piece of iron or copper (Cu) is polycrystalline.
水胆水晶，包括气态，液态，固态，有时候可以同时多态并存，无色居多，个别情况下可见红色，绿色，黄色，蓝色，黑色等。

Crystals seem special from all kinds of other rocks and minerals, but �?barring several Exclusive cases �?nearly all minerals disguise a crystalline construction beneath the surface.
发晶：无色、浅黄、浅褐等，可因含金红石常呈金黄、褐红等色，含电气石常呈灰黑色；含阳起石而呈灰绿色。
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：
Solids which have shorter-assortment order but absence extended-array buy are known as amorphous. Virtually any materials can be created amorphous by fast solidification through the soften (molten point out). This condition is unstable, as well as stable will crystallize in time. If your timescale for crystallization is decades, then the amorphous state appears secure.

There are actually just a few different unit-mobile shapes, so many alternative crystals share just one unit-cell variety. A crucial attribute of a unit cell is the quantity of atoms it includes. The whole range of atoms in the entire crystal is definitely the quantity in Each individual mobile multiplied by the number of unit cells. Copper and aluminum (Al) Just about every have a single atom for each unit cell, though zinc (Zn) and sodium chloride have two. Most crystals have only a few atoms for every device cell, but there are a few exceptions. Crystals of polymers, more info by way of example, have Many atoms in Every unit cell.
水晶饰品越来越受到人们的喜爱。中国、日本、韩国、美国等国家的人们还对水晶球情有独钟，喜欢将它们摆在家里或办公室里，认为水晶球有灵性，能保平安，带来财运。不过天然水晶不像看起来那么晶莹剔透，它也有瑕疵，我们在选购饰品的时候要注意。此外，我们还要掌握水晶的评价依据、选购方法，这样可以帮助我们在琳琅满目的水晶饰品中选到心仪的水晶。
