17These rings are indicative with the crystal composition of nickel and can be explained only by invoking wavelike Attributes of light.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。
按照透明度指标,水晶越透明,价格越高,好的透明的水晶加工出的成品晶莹剔透、光辉耀眼。透明度高的水晶能提升颜色的艳丽,否则显得呆板无灵性。光学水晶要求全透明、无双晶、无杂质。工艺水晶要求透明、少裂、少瑕疵。熔炼水晶要求透明,可有较多裂纹。三者价值依次降低,熔炼水晶只能作为熔炼水晶玻璃的原料。在工艺水晶中,晶体较大的,可用来做水晶眼镜和雕刻高档工艺品,因而价格较高。
发晶的价值取决于发的颜色、罕见性及大小,一般是发色鲜艳、块度大的价格高。水胆水晶的价值主要取决于水胆及晶体的大小、透明度的高低。如果水胆较大并有一定形态,便可加工成较为珍贵的工艺品。另外水胆中的水也有一定的科学研究价值,通过它们可了解几百万年前地球上水的成分及变化。
If you want to see how crystals are formed, you may do a little venture with your extremely personal kitchen and see the development of the crystals manifest with your individual eyes . This can be finished by putting a small amount of table salt into some typical tap drinking water, hold out 24 hours, and you'll see good cubed formations. This transpires since the drinking water is evaporating, which results in the atoms which make up the salt (the mineral) and also the drinking water to come nearer collectively.

第三种是“皮景”,因某些其他的矿物与水晶体共生,或由于其他的物质侵蚀而依附于水晶表面,或者是水晶受自然环境的影响,在水晶表面出现蚀象,形成了一些景象或图案,这种景观存在于水晶表面。
广义的包裹体是指宝石内部含有的与主晶宝石化学成分、物理性质等不同的物质。
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。

水玉:中国最古老的称法叫水玉,意谓似水之玉,又说是 �?千年之冰所�?�?。唐代诗人温庭筠《题李处士幽居》写道:�?水玉簪头白角巾,瑶琴寂历拂轻�?”。水玉一词最早频繁出于《山海经》:�?又东三百里,日堂庭之�?…�?多水�?”;�?丹山出焉,东南流注于洛水,其中多水玉 ”;�?逐水出焉,北流注于渭,其中多水玉 ”。司马相如《上林赋》曰�?�?水玉磊河 �?。水晶得名水玉,古人是看�?�?其莹如水,其坚如�?�?的质地。
水晶观赏石是天然水晶中最具代表的作品,具有其他宝石都不具备的观赏性。不论是玉石翡翠还是都要经过雕琢后次能体现他的价值,而水晶观赏石只需要将表面进行抛光,即展现出晶体内所包裹的物质,直接欣赏原汁原味的水晶石。
