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？
无色水晶以晶莹美丽、洁净透明着称。衡量无色水晶主要看它的纯度，越纯、越透明越好。干净的、无瑕疵的、杂质少的价值就高。无色的水晶如果很脏，就没有利用价值。
A primary thought in crystal constructions may be the unit mobile. It is the smallest unit of quantity that allows similar cells to get stacked jointly to fill all space. By repeating the sample of the unit cell over and over in all Instructions, the entire crystal lattice could be built. A cube is the simplest example of a device mobile. Two other illustrations are shown in Figure one. The main will be the unit mobile to get a experience-centred cubic lattice, and the next is for just a body-centred cubic lattice. These constructions are discussed in the next paragraphs.
Fig. three: A library of lattice symmetries can be accessed by shifting the particle Main and DNA shell.
There are actually many various crystals according to geometric buildings, crystal expansion, and materials. There is usually arrangements of hexagonal carbon atoms or amethyst which makes hexagonal pyramid structures.
第二种是“半包裹体”，在水晶结晶以后，由于受到地球引力的影响而产生的裂隙，晶体外的一些物质通过水晶的裂隙渗透到水晶内部，一部分包裹于水晶之中另一部分露于水晶之外。我们可以看到物质渗进水晶的裂迹，常被称为“通道”，这种包裹体所形成的景象相对地较受自然环境和时间的影响，相应的价值也比较�?。
水晶内部有多种矿物包裹体，形成的各种景观可以肉眼观测，这样的水晶就是包裹体水晶观赏石。由于水晶本身就是宝石，因此人们称誉包裹体水晶为“宝石级的观赏石”。包裹体水晶观赏石都具有独特性，具有极高欣赏和收藏价值。
Hexagonal �?Characterised by four axes, a few of that are equal in duration and intersect at one hundred twenty levels, having a fourth axis perpendicular to the opposite a few.
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：

地质学家目前为止对晶洞形成还没有广泛认同的理论，但相信晶洞可以在任何埋藏的空腔内形成。这些空腔可以是火成岩中的气泡、树根下的空穴，甚至动物挖的地洞。经过漫长时间，空腔的外壁变硬，溶解的矽酸盐或方解石沉积到内壁。再经过漫长的时间，缓慢渗入的矿物使得晶体在空腔内部结晶。

21You all understand how after you take a crystal prism and pass a beam of sunlight as a result of it, you will get a spectrum, which seems like a continual band of rainbow colours.
