17These rings are indicative of your crystal structure of nickel and will be described only by invoking wavelike properties 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。
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。

You will find a variety of crystals depending on geometric structures, crystal advancement, and materials. There is usually arrangements of hexagonal carbon atoms or amethyst that makes hexagonal pyramid structures.
Learn the way The form from the crystals decide the different minerals into familiesMinerals crystallize In accordance with certainly one of 7 motifs, known as crystal techniques.
对任何宝石来说，颜色都是非常重要的，水晶也不例外。如果是水晶晶体是有颜色的，如粉水晶、黄水晶、紫水晶等，其颜色评价的最高标准则是明艳动人，不带有灰色、黑色、褐色等其他色调。如粉水晶，颜色以粉红为佳；紫水晶，要求颜色为鲜紫，纯净不发黑；黄水晶，要求颜色不含绿色、柠檬色调，以金橘色为佳。对于发晶来说，晶体的颜色也是很重要的。相同发丝的金发晶，晶体完全无色（白水晶）和晶体略偏茶色，肉眼的视觉观感也是有差别的，所以前者的价格会高于后者。
As being a sizzling Alternative cools or a saturated Resolution evaporates, particles attract close sufficient for chemical more info bonds to kind. Crystals can also type from deposition directly from the gas section. Liquid crystals have particles oriented in an structured manner, like sound crystals, yet can easily move.
In the meantime, to make certain continued aid, we're displaying the location with out variations and JavaScript.
⑤化学稳定�?非常好，在常温下仅溶解于氢氟酸，不溶解于其它各类酸、碱。在高温高压条件下可溶解于碳酸钠溶液中。
天然性是水晶观赏石的基本特性。通常整体造型水晶矿物不饰雕琢就具备很高的观赏价值，但是包裹体水晶观赏石经常需要适当打磨抛光，这样更方便观赏水晶内部的包裹体。
There are actually other minerals and molecules that may type these crystal lattices. Snowflakes absolutely are a basic example of a around symmetric and geometrically patterned framework from ice crystals, and gemstones of all types are generally crystals.
水晶饰品越来越受到人们的喜爱。中国、日本、韩国、美国等国家的人们还对水晶球情有独钟，喜欢将它们摆在家里或办公室里，认为水晶球有灵性，能保平安，带来财运。不过天然水晶不像看起来那么晶莹剔透，它也有瑕疵，我们在选购饰品的时候要注意。此外，我们还要掌握水晶的评价依据、选购方法，这样可以帮助我们在琳琅满目的水晶饰品中选到心仪的水晶。
A different kind of crystalline carbon is predicated on a molecule with sixty carbon atoms named buckminsterfullerene (C60). The molecular form is spherical. Each carbon is bonded to a few neighbours, as in graphite, and the spherical shape is realized by a combination of twelve rings with five sides and 20 rings with 6 sides. Identical buildings were very first visualized because of the American architect R. Buckminster Fuller for geodesic domes.
