Not known Facts About Crystal

其它描述:《庶物异名疏》中说: �?水精出大秦国,一名黎�?�?。结晶完整的水晶晶体,就如参差交错的马齿,所以人们又叫它马牙石。先民们最早用它研磨成眼镜片,因而送它一个眼镜石的绰号。水晶有通称,也有俗称。广州一带称水晶叫晶玉,又名鱼脑冻;江苏东海县山民发现水晶会 �?窜火�?�?,于是给它起个放光石的俗名。世间一物多名,不足为奇,而像水晶拥有这么多的别称,实不多见。瞧,从水玉、水碧、白玉、玉瑛、水精石英、黎难、晶玉到菩萨石、马牙石、眼镜石、放光石、千年冰、高山冻、鱼脑冻等等,简直构成一部奇石鉴赏史。

③、粗抛光:是将模具压出之毛胚,以金刚石盘直接磨出成品之刻线。④、细抛光:在粗抛光之后,以抛光粉来磨成品至晶莹剔透为止。

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。

《全唐诗》卷七八五载《白雪歌》:“鸟啄冰潭玉镜开,风敲檐溜水晶折。”

Monoclinic �?Characterized by a few unequal axes, two of which intersect at an oblique angle, whilst the 3rd is perpendicular to your aircraft of one other two.

Springer Nature remains neutral with regards to jurisdictional promises in revealed maps and institutional affiliations.

Hexagonal �?Characterized by four axes, 3 of which can be equal in size and intersect at one hundred twenty levels, with a fourth axis perpendicular to one other a few.

水晶常以晶簇、晶洞形式产出,其中水晶洞一般存在于由火山喷发而形成的巨厚熔岩流层的火成岩与玄武岩中。火山喷发时所含的气体或热水溶蚀等作用导致岩层中出现大量的孔隙,当富含硅质矿物的流体进入较薄的熔岩孔隙中,且温、压条件合适时将结晶沉淀出水晶等矿物。

颜色:无色,浅至深的紫色,浅黄、中至深黄色,浅至深褐、棕色,绿至黄绿色,浅至中粉红。

天然性是水晶观赏石的基本特性。通常整体造型水晶矿物不饰雕琢就具备很高的观赏价值,但是包裹体水晶观赏石经常需要适当打磨抛光,这样更方便观赏水晶内部的包裹体。

玉石纹理如果能形成美丽的花纹、图案,其价格就高,如玛瑙内红白相间的色带有规律地排列,形成缠丝玛瑙时,碧玉中的不均匀颜色形成一种风景图案时,材料的价值将提高。当水晶内包裹体形成美丽的图案时,如幽灵水晶、风景水晶,或者针状包裹体呈束状排列时,其价值都高于普通的水晶。图案越美观、越有意境越好。

This crystal composition is responsible for the unique Bodily and chemical Houses of sodium chloride, such as its substantial melting issue, electrical conductivity, and skill to form ionic bonds very easily.
