8Where do we get this magic wand and crystal ball?我们到哪里获得这种魔棒和水晶玻璃球？

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。

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。

The ordered inside composition of large crystals, such as the fluorite and quartz shown in this article, is mirrored in their geometric styles.

C2 [ U ] clear glass of extremely good quality, normally with its area Reduce into sensitive styles:

Learn the way The form of the crystals establish the several minerals into familiesMinerals crystallize In line with certainly one of seven motifs, called crystal techniques.

⑦、镀彩：运用类似电镀的手法在水晶表面以不同的色彩，层面较薄，经摩擦可划伤�?；出现划痕，由于镀彩经常位于底部，因此在镀彩底部经常采用其它对象附着，如生肖文镇。

发晶：无色、浅黄、浅褐等，可因含金红石常呈金黄、褐红等色，含电气石常呈灰黑色；含阳起石而呈灰绿色。

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。

crystal The freshly crystallized quartz grains are characterized by elongate crystals oriented oblique into the shear band margins, defining a standard grain-shape foliation. 来自 Cambridge English Corpus We say the chain topology during the substantial w region functions given that the proverbial ' scratch-on-theglass ' desired within the natural chemistry laboratory check here to create crystals. 来自 Cambridge English Corpus The age scatter amid the person crystals might replicate incorporation of xenocrysts from earlier magmatic pulses or protoliths. 来自 Cambridge English Corpus The clinopyroxene forms neutral to pale brown, subhedral to anhedral crystals, sometimes made up of inclusions of plagioclase microlaths and opaque phases.

用手去触摸水晶，天然水晶通常温度要比人造水晶的要凉的多；用眼观察，天然水晶通常有棉絮状的包裹体，这个是人造水晶所没有的。

Crystal Lattices There are seven techniques of crystal buildings, which are also known as lattices or Area lattices:

Crystals are categorised usually categories, for instance insulators, metals, semiconductors, and molecular solids. One crystal of the insulator will likely be transparent and resembles a bit of glass. Metals are shiny Until they have rusted. Semiconductors are sometimes shiny and often transparent but are never ever rusty. Quite a few crystals is often categorized as an individual style of solid, while some have intermediate conduct. Cadmium sulfide (CdS) is often organized in pure variety and is a wonderful insulator; when impurities are extra to cadmium sulfide, it turns into a fascinating semiconductor.

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。
