诗中“胜美玉”，“过冰清”，写出水晶的质地美，而“亦欲应时明”则描绘出水晶充满灵性的动态美，耐人寻味。罗维是有独特眼光，懂得水晶真谛，第一个称赞水晶超过美玉的伟大诗人。他的认识已被千年之后的科学理论所证实；以水晶为直接吟咏对象的诗篇还有：

③、粗抛光：是将模具压出之毛胚，以金刚石盘直接磨出成品之刻线。④、细抛光：在粗抛光之后，以抛光粉来磨成品至晶莹剔透为止。

10This will be the silicon chip—somewhat chip of silicon crystal.这是硅芯片——一个硅晶体的小芯片。

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。

You will also find several materials that resemble crystals but are actually polycrystals. Polycrystals variety when microscopic crystals fuse together to sort a solid. These components usually do not include requested lattices.

Learn how the shape of the crystals figure out the different minerals into familiesMinerals crystallize As outlined by considered one of seven motifs, called crystal methods.

水晶与高档宝石的净度要求有很大不同。高档宝石稀少罕见，所以一般人们普遍对高档宝石的净度不会过于苛求。而水晶的产量着实大得惊人，所以通常人们会要求水晶净度越高越好，尽量避免有较明显的内含物的水晶。

Hexagonal �?Characterised by four axes, three of which might be equivalent in size and intersect at one hundred twenty levels, having a fourth axis perpendicular to the opposite three.

水晶是有成色等级之分，影响水晶价位的因素很多，不像钻石以4C就可以判定，所以大家要多听多看多比较才能真正辨别出来。一般的标准是水晶石越大越好，越透越好，颜色越娇嫩越好，形状越典型越好。不过最重要还是自己喜欢，而选购时辨识真伪的方法大致有下列几种：

You will find other minerals and molecules that can type these crystal lattices. Snowflakes certainly are a classic illustration of a roughly symmetric and geometrically patterned construction from ice crystals, and gemstones of all varieties are generally crystals.

Crystals are categorised in general groups, such as insulators, metals, semiconductors, and molecular solids. An individual crystal of an insulator will likely be transparent and resembles a piece of glass. Metals are shiny Except if they've got rusted. Semiconductors are occasionally shiny and occasionally clear but are hardly ever rusty. Many crystals can be categorised as an individual kind of good, while others have intermediate conduct. Cadmium Crystal sulfide (CdS) could be geared up in pure kind and is a superb insulator; when impurities are added to cadmium sulfide, it will become a fascinating semiconductor.

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。
