These crystals were formed over one million years ago In the Earth's crust. They come about when the liquid during the Earth consolidates along with the temperature chills. Other crystals sort if the liquid helps make its way throughout the clefts and dispense minerals to the clefts.

10This is definitely the silicon chip—a bit chip of silicon crystal.这是硅芯片——一个硅晶体的小芯片。

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。

. These four buildings comprise a lot of the binary crystals with equivalent quantities of cations and anions.

你们都知道，拿起一个水晶棱镜，让一束阳光通过它，就会得到一个光谱，看起来就像一条连续的彩虹色带。

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。

水晶包裹体丰富多彩，从气体、液体到各种矿物质，甚至宝石，均可被包含于水晶内，各种包裹体所形成的景象更是变化万千。按照包裹体的内容，常把包裹体水晶分为一下八类：

crystal The recently crystallized quartz grains are characterized by elongate crystals oriented oblique for the shear band margins, defining a typical grain-shape foliation. 来自 Cambridge English Corpus We are saying the chain topology while in the large w area acts since the proverbial ' scratch-on-theglass ' desired while in the natural chemistry laboratory to produce crystals. 来自 Cambridge English Corpus The age scatter amid the person crystals might reflect incorporation of xenocrysts from before magmatic pulses or protoliths. 来自 Cambridge English Corpus The clinopyroxene check here sorts neutral to pale brown, subhedral to anhedral crystals, occasionally containing 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。

⑨、喷砂：立体感弱，较平整，无凹凸感，机器雕刻文字、图形等后进行效果处理。成本低制作快。

对于紫水晶黄水晶这样的单色水晶，通常要观察它的二色性，即使是最顶级的紫水晶黄水晶也是有色差的，通过这个方法可以鉴别是否加色。
