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：

对水晶进行评价主要依据其颜色、透明度、大小、净度、特殊图案及是否有光学效应等方面。以颜色纯正，浓度较高，内部无瑕为好。种类上紫晶最贵，其次为黄晶、烟晶、无色水晶和芙蓉石。有特殊光学效应的水晶的价格更高。

Crystalline structure is characterised by a geometrical, repeating pattern of symmetric molecular composition. The arrangement of atoms sorts these requested, repeating designs.

时尚的收藏爱好者喜欢收藏天然水晶，却常常因为在市场上面对大量的合成水晶看走了眼。市面上的水晶：
Crystals are practically nothing in excess of an ordered arrangement of molecules or atoms. Crystals can be found in many various sizes and shapes, and each has diverse properties. Whatever they are made of decides how it's going to sort.
Among the binary crystals, the easiest structures to visualize are People with equivalent quantities get more info of The 2 types of atoms. The framework of sodium chloride is based on the dice. To construct the lattice, the sodium and chlorine atoms are placed on alternate corners of a dice, and the framework is repeated (Determine 3B).
看文化：水晶里面的包裹体象形，能与文化、宗教及历史有所牵连的话，价格往往会比水晶本身的价值高出几倍甚至几百倍。
The essential models of solids are both atoms or atoms which have blended into molecules. The electrons of an atom shift in orbits that variety a shell construction round the nucleus. The shells are stuffed in a scientific purchase, with each shell accommodating only a small range of electrons. Distinctive atoms have distinct figures of electrons, which might be dispersed within a characteristic electronic framework of loaded and partly filled shells.
水晶的价值还与块体大小有关，同样的颜色和净度级别，块越大越难得。有时候质量级别虽然低一些，但块体够大，也可能价格高于高级别的小晶体
在透明的水晶中，隐裂纹呈亮晶晶的片状，有时还会有晕彩效应。这些裂纹是水晶在生长过程中，遇到外力挤压而在内部产生的一些隐形裂纹，隐裂纹在芙蓉石、紫水晶、白水晶球及白水晶柱中都很常见。有的裂纹后来被物质填充，形成愈合的裂纹，也就是原来的裂纹又长住了。这种裂纹对水晶的影响相对要小一些。
