晶及其石英岩类玉石是中低档宝玉石，虽比不上钻石、红蓝宝石的高贵，但在加工中如果构思巧妙而且加工精细，同样具有很高的价值。如中国传统的玛瑙“虾盘”、“龙盘”、“水漫金山�?水胆玛瑙摆件)都被誉为国家级宝玉石。
If you want to see how crystals are shaped, you may do a little project in your quite personal kitchen area and see the formation of the crystals happen using your have eyes . This may be finished by Placing a small amount of desk salt into some standard faucet drinking water, wait around 24 hrs, and you'll see good cubed formations. This transpires as the h2o is evaporating, which leads to the atoms that make up the salt (the mineral) along with the h2o to return closer jointly.
《全唐诗》卷七八五载《白雪歌》：“鸟啄冰潭玉镜开，风敲檐溜水晶折。”
结晶�?When sea water is permitted to evaporate, salt crystals are deposited. 海水蒸发后，盐的结晶体就沉淀下来。
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。
Hexagonal �?Characterized by four axes, 3 of that happen to be equal in length and intersect at a hundred and twenty levels, by using a fourth axis perpendicular to the other a few.
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：

. The 2nd layer is shaded during the determine. It's website got the same airplane-triangular framework; the atoms sit during the holes fashioned by the main layer.

⑦双色水晶：一种紫色和黄色共存一体的水晶，紫色、黄色之间界限较明显，分别占据晶块的一部分。
The C60 molecules, also known as buckyballs, are quite sturdy and Nearly incompressible. Crystals are shaped such the balls are arranged in an fcc lattice with a just one-nanometre spacing among the centres of adjacent balls. The related C70 molecule has The form of a rugby ball; C70 molecules also form an fcc crystal when stacked alongside one another. The solid fullerenes variety molecular crystals, with weak binding—provided by van der Waals interactions—among the molecules.
