景观水晶，就是包裹体组成各种造型特异的水晶，有的似山水，有的似人物，有些像文字，有些像动物，植物，器物等等。
第一种是“全包裹体”，在水晶结晶的时候把这些物质包裹在晶体里面，这类包裹体所形成的各种景象，大多保持了水晶结晶时的原状，也就是说保存了几亿年的原状，极少受到自然环境的影响。
水胆水晶，包括气态，液态，固态，有时候可以同时多态并存，无色居多，个别情况下可见红色，绿色，黄色，蓝色，黑色等。
⑧、雕刻：立体感强，工艺高，做工精细，成本高。分手工雕刻图形、机器雕刻文字。
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。
There exists a similar directive about crystal glass which differentiates between whole direct crystal, lead crystal and crystal.
Numerous crystals behave like butter in that they're challenging at lower temperatures but smooth at greater temperatures. They may be known as solids in the slightest degree temperatures under their melting issue. A doable definition of the good is surely an item that retains its shape if still left undisturbed. The pertinent challenge is how much time the article retains its condition. A really viscous fluid retains its form for one hour but not a 12 months. A strong must hold its form extended than that.
颜色：无色，浅至深的紫色，浅黄、中至深黄色，浅至深褐、棕色，绿至黄绿色，浅至中粉红。
天然性是水晶观赏石的基本特性。通常整体造型水晶矿物不饰雕琢就具备很高的观赏价值，但是包裹体水晶观赏石经常需要适当打磨抛光，这样更方便观赏水晶内部的包裹体。
水晶形成后由于外力作用或某种人为原因使水晶产生大的裂隙或裂纹，这种裂纹有大有小，对水晶的影响也有大小之分。

The C60 molecules, also known as buckyballs, are fairly strong and almost incompressible. Crystals are shaped this kind of which the balls are organized in an fcc lattice using a 1-nanometre spacing concerning the centres of adjacent balls. The get more info comparable C70 molecule has the shape of the rugby ball; C70 molecules also sort an fcc crystal when stacked jointly. The strong fullerenes sort molecular crystals, with weak binding—furnished by van der Waals interactions—between the molecules.
