The best Side of Crystal

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：

the strong condition of numerous straightforward substances, that have a regular condition and surfaces organized in similar patterns

A crystal composition focuses on how the atoms are organized In the crystal. Even so, crystallographers are interested in the general condition and size of the crystal in addition to its exterior features. To accomplish this, they should learn about the crystal method.

Tetragonal: These crystals type prisms and double pyramids. The framework is like a cubic crystal, other than one axis is for a longer period than the opposite.

这种水晶观赏石特指水晶晶簇，它是众多单晶体集中生长在一起的晶体组合。晶簇以其晶莹剔透、独特造型而享誉水晶赏石界。

Lattices could possibly have just one lattice place per cell or multiple, yielding a total of 14 Bravais crystal lattice forms. Bravais lattices, named for physicist and crystallographer Auguste Bravais, describe the 3-dimensional array made by a set of discrete details.

根据包裹体和主晶宝石之间形成的先后关系可将水晶的包裹体划分以下三种类�?

Hexagonal �?Characterised by four axes, 3 of that happen to be equal in duration and intersect at one hundred twenty degrees, that has a fourth axis perpendicular to the opposite a few.

22Working from what America currently knows about itself, the bureau's specialists and also other demographers supply an irresistible, if clouded, crystal ball among the their visions.

地质学家目前为止对晶洞形成还没有广泛认同的理论，但相信晶洞可以在任何埋藏的空腔内形成。这些空腔可以是火成岩中的气泡、树根下的空穴，甚至动物挖的地洞。经过漫长时间，空腔的外壁变硬，溶解的矽酸盐或方解石沉积到内壁。再经过漫长的时间，缓慢渗入的矿物使得晶体在空腔内部结晶。

You can find other minerals and molecules that will type these crystal lattices. Snowflakes can be a vintage example of a around symmetric Crystal and geometrically patterned construction from ice crystals, and gemstones of all versions are usually crystals.

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。

水晶的价值根据品质、块体的大小、美感和产量多少的不同相差较大。遇到好的天然水晶要敢于下手，但好的水晶一般大家都想得到，值与不值，就要看经验了。由于天然水晶的开采和制作原因，没有瑕疵的水晶很难得到，纯净的饰品要达到与合成水晶媲美的品质，实在是很难得。另外，由于水晶的特性，在佩戴过程中，也会改变其等级，比如因为某种原因，有可能会逐渐产生较大裂纹。
