These crystals had been shaped above one million many years ago inside the Earth's crust. They happen once the liquid inside the Earth consolidates along with the temperature chills. Other crystals kind once the liquid tends to make its way through the clefts and dispense minerals in to the clefts.
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。
景观水晶，就是包裹体组成各种造型特异的水晶，有的似山水，有的似人物，有些像文字，有些像动物，植物，器物等等。
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。
看抛光：抛光的好坏直接影响到水晶制品的身价。抛光分为软抛光与硬抛光。
⑧、雕刻：立体感强，工艺高，做工精细，成本高。分手工雕刻图形、机器雕刻文字。
水晶的评价标准和高端宝石有所不同。多数高端宝石把颜色放在评价的第一位，而对水晶来说，颜色和净度（水晶行业称作晶体）是近乎同等重要的因素：
如果水晶内部杂质中有传说中人物的造型，如佛、星座、生肖等价值可能要高于同等颜色和净度的水晶。

crystal The freshly crystallized quartz grains are characterised by elongate crystals oriented oblique towards the shear band margins, defining a typical grain-condition foliation. 来自 Cambridge English Corpus We say the chain topology within the higher w region functions as being the proverbial ' scratch-on-theglass ' needed from the natural chemistry laboratory to generate crystals. 来自 Cambridge English Corpus The age scatter among the individual crystals could reflect 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 that contains inclusions of plagioclase microlaths and opaque phases.

国家还并未给天然水晶提供一个等级划分的具体标准，水晶品种繁杂，每一品种都有他不同的评判标准。
Crystals are labeled in general types, including insulators, metals, semiconductors, and molecular solids. Only one crystal of the insulator will likely be transparent and resembles a bit of glass. Metals are shiny Except they may have rusted. Semiconductors are occasionally shiny and occasionally transparent but are hardly ever rusty. A lot of crystals is often categorised as one form of sound, here while some have intermediate behaviour. Cadmium sulfide (CdS) may be ready in pure form and is a wonderful insulator; when impurities are additional to cadmium sulfide, it gets a fascinating semiconductor.
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。
