These crystals were shaped around 1,000,000 yrs back Within the Earth's crust. They arise when the liquid inside the Earth consolidates and the temperature chills. Other crystals type when the liquid would make its way throughout the clefts and dispense minerals in to the clefts.
23Sometimes, nevertheless, the crystal form of the silicate inclusions is observed to resemble much more carefully The interior framework of diamond than that of other silicate minerals.然而，有时观察到硅酸盐包裹体的晶体形态比其他硅酸盐矿物更接近金刚石的内部结构。
天然水晶是不可再生资源，随着开发的深入，天然水晶存量已越来越少，为了可持续发展，东海县政府早就制定了保护本地资源，鼓励开发海外水晶资源的政策，但是，海外资源也越来越少，很多国家都提高了开采和出口天然水晶的门槛，进入东海市场的外国水晶价格连年暴涨，其中观赏水晶比普通水晶涨价更快。
Significant crystals of diamond are important gemstones. The crystal has other fascinating Homes; it's got the highest sound velocity of any stable and is the best conductor of warmth. Aside from diamond, another widespread form of carbon is graphite, that is a layered materials. Just about every carbon atom has 3 coplanar in close proximity to neighbours, forming an arrangement known as the honeycomb lattice. 3-dimensional graphite crystals are received by stacking identical levels.
根据美国已经了解的情况，统计局的专家和其他人口统计学家在他们的视野中提供了一个不可抗拒的水晶球。
当二氧化硅结晶完美时就是水晶；结晶不完美的就是石英：二氧化硅胶化脱水后就是玛瑙；二氧化硅含水的胶体凝固后就成为蛋白石；二氧化硅晶粒小于几微米时，就组成玉髓、燧石、次生石英岩。
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。
11I diligently opened the package and located a crystal bell within.我小心地打开包裹，发现里面有一个水晶钟。
Crystals will often be viewed as something of immense elegance, and they are generally applied with diamonds or other stones to make items of jewelry. Nearly all crystals now are man-manufactured in laboratories.
A crystal process refers to the classification of crystals determined by the geometric arrangement and symmetry in their lattice structures. There are actually seven primary crystal techniques:
. The next layer is shaded in the figure. It has the identical plane-triangular framework; the atoms sit from the holes formed by the very first layer. The 1st layer has two equal sets of holes, though the atoms of the next layer can occupy just one set. The 3rd layer, labeled C
You'll find other minerals and molecules that can form these crystal lattices. Snowflakes here absolutely are a traditional illustration of a around symmetric and geometrically patterned structure from ice crystals, and gemstones of all varieties are typically crystals.
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。
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。
