水晶表面坑洼的地方,有的深,有的浅,这是水晶在成长过程中自然形成的,并非是人为造成的损伤。缺陷位置本来包有其他矿物晶体,由于包裹体和水晶结合部位的结合力不强,当表面抛光时,矿体脱落,留下空位。这种缺陷在绿幽灵、钛晶、金发晶上都比较常见。
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。
结晶的形状非常细小,需要用显微镜才能看得清楚,外观上看起来是平滑、块状。常见最多的是各式玛瑙
The requested internal composition of enormous crystals, like the fluorite and quartz demonstrated right here, is reflected of their geometric styles.
断口:贝壳状。断口也叫破口。它是指矿物被打击后产生不规则的破裂,破裂裂面凹凸不平称为断口。根据断口的形状可分为贝壳状和锯齿状。
They'll finally come up with a wonderful minimal uniform cluster of atoms, This is certainly the entire process of escalating crystals. The more they are able to come alongside one another, the more of a formation is going to be obvious to the bare eye. Scientists can ascertain what mineral They're looking at by how the crystals kind.
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�?
11I meticulously opened the offer and located a crystal bell inside.我小心地打开包裹,发现里面有一个水晶钟。
水晶是有成色等级之分,影响水晶价位的因素很多,不像钻石以4C就可以判定,所以大家要多听多看多比较才能真正辨别出来。一般的标准是水晶石越大越好,越透越好,颜色越娇嫩越好,形状越典型越好。不过最重要还是自己喜欢,而选购时辨识真伪的方法大致有下列几种:
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。
15The trick to a good thermoelectric content is actually a crystal structure through which electrons can move freely.制造一种好的热电材料的关键是,需要一种电子可以自由流动的晶体结构。
水晶形成后由于外力作用或某种人为原因使水晶产生大的裂隙或裂纹,这种裂纹有大有小,对水晶的影响也有大小之分。
14For example, We've Quartz crystal clocks and watches exact to within a person moment a year.例如,我们使用的每年误差不超过1分钟的石英水晶钟表和手表。
21You all know how any time you have a crystal prism and pass a beam of sunlight by means of it, you get a spectrum, which looks like a more info ongoing band of rainbow colors.
