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？
按照透明度指标，水晶越透明，价格越高，好的透明的水晶加工出的成品晶莹剔透、光辉耀眼。透明度高的水晶能提升颜色的艳丽，否则显得呆板无灵性。光学水晶要求全透明、无双晶、无杂质。工艺水晶要求透明、少裂、少瑕疵。熔炼水晶要求透明，可有较多裂纹。三者价值依次降低，熔炼水晶只能作为熔炼水晶玻璃的原料。在工艺水晶中，晶体较大的，可用来做水晶眼镜和雕刻高档工艺品，因而价格较高。
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：
看原料：选料精良的水晶制品，应看不到胶口及棉絮；质地纯净、光润、晶莹为好。
Crystalline composition is characterised by a geometric, repeating pattern of symmetric molecular construction. The arrangement of atoms forms these requested, repeating styles.
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。
30Three times went earlier, and I was shocked to check out it once again: the many openings were sewed up by slim and white thread and so they seemed like the ice crystal on Wintertime's branches in the north.
There's a similar directive about crystal glass which differentiates concerning full direct crystal, direct crystal and crystal.
Amongst the binary crystals, the simplest buildings to visualise are Individuals with equal quantities of the two kinds of atoms. The construction of sodium chloride is based on the cube. To construct the lattice, the sodium and chlorine atoms are put on alternate corners of a cube, and also the structure is recurring (Figure 3B).
多色�?无色水晶没有多色性。有色水晶有弱到强的多色�?表现为体色的不同深浅。

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。
Crystals are categorized usually groups, including insulators, metals, semiconductors, and molecular solids. Only one crystal of an insulator is frequently transparent and resembles a piece of glass. Metals are shiny unless they've got rusted. Semiconductors are sometimes shiny and in some cases transparent but are by no means rusty. Quite a few crystals is usually classified as a single type of solid, while some have intermediate conduct. Cadmium sulfide (CdS) could be well prepared in pure form and is a superb insulator; when impurities are included to cadmium sulfide, it gets an interesting semiconductor.
