Crystal Can Be Fun For Anyone

17These rings are indicative with the crystal structure of nickel and may be defined only by invoking wavelike Homes of sunshine.这些光圈表明了了镍的晶体结构,而且只能通过光线中波的特征来解释。

12He attempted once again in numerous other towns and succeeded with Crystal Caramels.他又在其他几个城市再次尝试,并成功制出了水晶焦糖。

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。

看抛光:抛光的好坏直接影响到水晶制品的身价。抛光分为软抛光与硬抛光。

你们都知道,拿起一个水晶棱镜,让一束阳光通过它,就会得到一个光谱,看起来就像一条连续的彩虹色带。

水晶的评价标准和高端宝石有所不同。多数高端宝石把颜色放在评价的第一位,而对水晶来说,颜色和净度(水晶行业称作晶体)是近乎同等重要的因素:

Crystals are almost nothing over an ordered arrangement of molecules or atoms. Crystals come in many alternative styles and sizes, and every one has distinct characteristics. What they are created of establishes how it is going to variety.

Among the binary crystals, the best constructions to visualise are All those with equivalent figures of the two kinds of atoms. The structure of sodium chloride is based over a dice. To construct the lattice, the sodium and chlorine atoms click here are placed on alternate corners of the dice, and the composition is repeated (Figure 3B).

. The 2nd layer is shaded within the figure. It's got the identical airplane-triangular structure; the atoms sit within the holes fashioned by the main layer. The primary layer has two equivalent sets of holes, but the atoms of the second layer can occupy just one set. The third layer, labeled C

正常的水晶在生长时,多可以发现和柱形尖端棱线平行的生长纹(advancement strains)。由于在地底、岩洞中的生长空间多狭窄,尤其在遇到地震时,或地壳变动时,甚至容易遭到其他矿石的挤压,常常会压迫产生不同的「晶面」。还有,当水晶还是在液态状的时候,常常也会包覆着其他的矿石、泥灰一起结晶成长,如金红石(稍后变成发晶)、火山泥灰(稍后变成幻影水晶)等等。所有的这些,都是「自然的一部分」,请不要视为「瑕疵」。

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。
