发晶的价值取决于发的颜色、罕见性及大小，一般是发色鲜艳、块度大的价格高。水胆水晶的价值主要取决于水胆及晶体的大小、透明度的高低。如果水胆较大并有一定形态，便可加工成较为珍贵的工艺品。另外水胆中的水也有一定的科学研究价值，通过它们可了解几百万年前地球上水的成分及变化。
Encyclopaedia Britannica's editors oversee subject places by which they've got considerable expertise, irrespective of whether from many years of expertise attained by working on that content or by way of examine for an advanced diploma.

You'll find many various crystals according to geometric buildings, crystal expansion, and material. There may be preparations of hexagonal carbon atoms or amethyst which makes hexagonal pyramid buildings.
They may sooner or later come up with a great small uniform cluster of atoms, this is the process of developing crystals. The more they will appear together, the more of the formation will be noticeable to your naked eye. Scientists can ascertain what mineral They can be looking at by how the crystals variety.
解理：无解理。所谓解理是指矿物被打击时，沿一定方向有规则地裂开形成光滑平面的性质。根据解理的程度可以分为五类：极完全解理、完全解理、中等解理、不完全解理和无解理，水晶属于无解理。

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。
The sodium chloride crystal lattice is characterised because of the near packing on the constructive sodium ions and negative chloride ions. Every sodium ion is surrounded by 6 chloride ions, and each chloride ion is surrounded by 6 sodium ions, creating a extremely stable and symmetrical construction.
