天然的水晶一般都会有絮状(绵绺),也就是大家俗称的瑕疵,这是液体水落石出和二氧化碳的小孔穴,而人工合成的水晶就不会有这样的特征。
无色水晶以晶莹美丽、洁净透明着称。衡量无色水晶主要看它的纯度,越纯、越透明越好。干净的、无瑕疵的、杂质少的价值就高。无色的水晶如果很脏,就没有利用价值。
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。
水碧:《山海经》中,水晶又被称作水碧: �?又南三百里,日耿山,无草木,多水碧 �?,郭璞注�?�?亦水玉类 ”。这种称谓常被文人所引用,晋代郭景纯《璞江赋》道�?�?鬼,水碧�?�?。水晶又有人称它叫玉瑛。《符瑞图》载�?美石似玉,水精谓之玉瑛也�?”

Crystals are often seen as some thing of enormous splendor, and they are generally utilized with diamonds or other stones to create items of jewellery. Virtually all crystals now are man-produced in laboratories.
crystal The recently crystallized quartz grains are characterized by elongate crystals oriented oblique to the shear band margins, defining a typical grain-condition foliation. 来自 Cambridge English Corpus We say the chain topology in the superior w region functions because the proverbial ' scratch-on-theglass ' needed from the organic and natural chemistry laboratory to produce crystals. 来自 Cambridge English Corpus The age scatter between the individual crystals may perhaps mirror incorporation of xenocrysts from earlier magmatic pulses or protoliths. 来自 Cambridge English Corpus The clinopyroxene kinds neutral to pale brown, subhedral to anhedral crystals, sometimes made up of inclusions of plagioclase microlaths and opaque phases.
被主体水晶所捕获的包裹体。原生包裹体通常为固相,形态较规则。水晶中典型的原成包裹体有金红石、电气石、黄铁矿等,也会见到岩石碎屑或集合体。
Crystallography would be the research click here of crystals, and it offers with every thing from great geometric designs to seemingly random conglomerations of particles and minerals.
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。
