8Where can 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？
杂质、裂纹越少越好。质地好的水晶制品，应看不到星点状、云雾状和絮状分布的气液包裹体或组成玉石的颗粒。有裂纹、斑点，则属于次品。
10This is the silicon chip—a little chip of silicon crystal.这是硅芯片——一个硅晶体的小芯片。
Encyclopaedia Britannica's editors oversee topic areas by which they may have substantial expertise, whether from years of expertise acquired by working on that content or by means of analyze for a complicated diploma. They create new content material and verify and edit content gained from contributors.
There are actually numerous crystals determined by geometric structures, crystal expansion, and materials. There can be preparations of hexagonal carbon atoms or amethyst which makes hexagonal pyramid structures.
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。
水晶原石观赏石，从字面意义理解：观赏水晶石的原貌，即经过抛光去皮后的包裹体水晶和原色水晶，不需雕刻不求象形就具有非常高的观赏价值和收藏价值。此类水晶观赏石对质地要求非常之高，水晶晶体通透干净，颜色艳丽，意境鲜明深刻的价值就高，它的价值特点就好比钻石，实实在在石头本身的价值。

One of the binary crystals, the simplest structures to visualise are those with equal figures of the two types of atoms. The construction of sodium chloride relies on the cube. To assemble the lattice, the sodium and chlorine atoms are placed on alternate corners of the dice, and also the framework is repeated (Figure 3B).

被主体水晶所捕获的包裹体。原生包裹体通常为固相，形态较规则。水晶中典型的原成包裹体有金红石、电气石、黄铁矿等，也会见到岩石碎屑或集合体。
Crystals are not merely renowned for their physical visual appearance, but distinctive crystals of different materials and formations may lead to an unlimited a number of utilizes and Bodily Qualities.
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。
Binary crystals are found in several constructions. Some pairs of aspects kind more than one structure. At place temperature, cadmium sulfide may well crystallize either within the zinc blende or wurtzite framework. Alumina also has two probable structures at space temperature, α-alumina (corundum) and β-alumina. Other binary crystals exhibit distinctive buildings at diverse temperatures. Among the most elaborate crystals are Individuals of silicon dioxide (SiO2), which has 7 unique constructions at many temperatures and pressures; the commonest of those structures is quartz.
