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。
Crystals are wonderful rock formations that have impressed human beings for thousands of decades. They're used for lots of different things, not only for decoration. Lots of the 1st radios at any time invented utilized crystals to transmit the radio waves. Some devices, like quartz watches and laser crystals, use special properties and harmonic capabilities of crystals to help make very correct measurements and changes.
Chemical Bonds The categories of chemical bonds fashioned involving atoms or groups of atoms in crystals rely upon their size and electronegativity. There are actually 4 classes of crystals as grouped by their bonding:
③次生包裹体:指主体水晶形成后,由于环境的变化使得主晶周围的一些物质沿裂隙进入到其内部而形成的包裹体。形成的原因有出熔作用、裂隙的结晶化、以及放射性元素破坏的作用等。水晶典型的次生包裹体有胶花水晶中的氧化铁充填物等。
You'll find a variety of crystals based on geometric constructions, crystal development, and substance. There is often preparations of hexagonal carbon atoms or amethyst which makes hexagonal pyramid constructions.
发晶,包括钛晶,铜顺发,绿发晶,黑发晶,银发晶,杂色发晶,其中钛晶最珍贵,少数钛晶价值可比钻石,红宝石和蓝宝石以及祖母绿。
30Three days went previous, and I used to be stunned to determine it again: each of the openings were sewed up by slim and white thread plus they seemed just like the ice crystal on Winter season's branches from the north.
市场上有很多人把熔炼水晶也叫做合成水晶,那是不准确的,一般都是以水晶废料为原料在高温高压下熔炼出来的,而不是结晶成的,不具备水晶的晶体特性,所以不能把熔炼水晶与合成水晶混为一谈;但是熔炼水晶耐高温,用优质二氧化硅熔炼成的熔炼水晶可以做成实用产品比如水晶杯、烤盘、茶具等,实际上一代伟人毛泽东主席的水晶棺就是选用东海优质水晶熔炼而成的。
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。
多色�?无色水晶没有多色性。有色水晶有弱到强的多色�?表现为体色的不同深浅。

Molecular Crystals: Total molecules are bonded to each other within an arranged fashion. A superb illustration is actually a sugar crystal, more info which incorporates sucrose molecules.
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。
矿物成分:针铁矿、赤铁矿、金红石、磁铁矿、电气石、石榴石、云母、绿泥石等形成了包裹体水晶,如发晶、钛晶、绿幽灵等,发晶中则含有肉眼可见的似头发状的针状矿物的包裹体形成。含锰和铁者称紫水晶;含铁�?;呈金黄色或柠檬�?)称黄水晶;含锰和钛呈玫瑰色者称蔷薇石英,即粉水晶;烟色者称烟水晶;褐色者称茶晶;黑色透明者称为墨晶。
