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？
Crystals are wonderful rock formations which have shocked individuals for thousands of many years. These are utilized for lots of different things, not only for decoration. Most of the initially radios at any time invented made use of crystals to transmit the radio waves. Some devices, like quartz watches and laser crystals, use Unique Qualities and harmonic abilities of crystals for making remarkably precise measurements and adjustments.
人造水晶分为熔炼水晶与养殖晶：据水晶专家汪毅的阐述，随着水晶的价值提高，喜欢的人增多，水晶也引起了作伪者的兴趣，现阶段中国水晶市场常见的造假方法为：
Big crystals of diamond are useful gemstones. The crystal has other fascinating properties; it has the best seem velocity of any solid and is the best conductor of warmth. Moreover diamond, one other frequent sort of carbon is graphite, which happens to be a layered substance. Each individual carbon atom has a few coplanar close to neighbours, forming an arrangement known as the honeycomb lattice. A few-dimensional graphite crystals are obtained by stacking identical levels.
断口：贝壳状。断口也叫破口。它是指矿物被打击后产生不规则的破裂，破裂裂面凹凸不平称为断口。根据断口的形状可分为贝壳状和锯齿状。
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�?。
30Three times went past, and I had been stunned to find out it again: each of the openings ended up sewed up by skinny and white thread and they appeared like the ice crystal on winter's branches during click here the north.
Crystals might be grown under moderate conditions from all ninety two The natural way transpiring things besides helium, and helium is often crystallized at lower temperatures through the use of 25 atmospheres of pressure.
Metallic Crystals: Metals often kind metallic crystals, wherever some of the valence electrons are totally free to move all through the lattice. Iron, by way of example, can type various metallic crystals.
幽灵水晶，分绿幽灵，红幽灵，白幽灵等，主要组成为绿泥石，其中绿幽灵属于珍贵品种。
⑥、丝印：水晶表面附有不同的色料进行效果处理，颜色层面较厚，着力后方可脱落。
水晶的价值还与块体大小有关，同样的颜色和净度级别，块越大越难得。有时候质量级别虽然低一些，但块体够大，也可能价格高于高级别的小晶体
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。
The C60 molecules, also called buckyballs, are pretty solid and almost incompressible. Crystals are shaped these kinds of that the balls are arranged in an fcc lattice that has a just one-nanometre spacing involving the centres of adjacent balls. The equivalent C70 molecule has The form of the rugby ball; C70 molecules also form an fcc crystal when stacked jointly. The stable fullerenes variety molecular crystals, with weak binding—furnished by van der Waals interactions—involving the molecules.
