天然的水晶一般都会有絮状（绵绺），也就是大家俗称的瑕疵，这是液体水落石出和二氧化碳的小孔穴，而人工合成的水晶就不会有这样的特征。
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。
A basic notion in crystal structures may be the unit cell. It is the smallest device of volume that permits identical cells being stacked together to fill all Area. By repeating the pattern of the unit mobile repeatedly in all Instructions, the entire crystal lattice might be made. A cube is The only illustration of a device cell. Two other illustrations are shown in Determine one. The initial is the unit mobile for the experience-centred cubic lattice, and the 2nd is for your entire body-centred cubic lattice. These constructions are defined in the following paragraphs.
③次生包裹体：指主体水晶形成后，由于环境的变化使得主晶周围的一些物质沿裂隙进入到其内部而形成的包裹体。形成的原因有出熔作用、裂隙的结晶化、以及放射性元素破坏的作用等。水晶典型的次生包裹体有胶花水晶中的氧化铁充填物等。

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。

《古今小说·李公子救蛇获称心》：“器皿皆是玻璃、水晶、琥珀、玛瑙为之，曲尽巧妙，非人间所有。”
水晶观赏石是天然水晶中最具代表的作品，具有其他宝石都不具备的观赏性。不论是玉石翡翠还是都要经过雕琢后次能体现他的价值，而水晶观赏石只需要将表面进行抛光，即展现出晶体内所包裹的物质，直接欣赏原汁原味的水晶石。
