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。

人造水晶分为熔炼水晶与养殖晶：据水晶专家汪毅的阐述，随着水晶的价值提高，喜欢的人增多，水晶也引起了作伪者的兴趣，现阶段中国水晶市场常见的造假方法为：
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。
断口：贝壳状。断口也叫破口。它是指矿物被打击后产生不规则的破裂，破裂裂面凹凸不平称为断口。根据断口的形状可分为贝壳状和锯齿状。

水晶的评价标准和高端宝石有所不同。多数高端宝石把颜色放在评价的第一位，而对水晶来说，颜色和净度（水晶行业称作晶体）是近乎同等重要的因素：

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 definition of the stable appears here clear; a good is normally thought of as remaining challenging and firm. Upon inspection, having said that, the definition turns into much less easy. A dice of butter, for example, is hard just after staying saved inside a refrigerator and is particularly clearly a reliable. Immediately after remaining about the kitchen counter for per day, a similar cube results in being very smooth, and it can be unclear In case the butter ought to even now be thought of a sound.
用手去触摸水晶，天然水晶通常温度要比人造水晶的要凉的多；用眼观察，天然水晶通常有棉絮状的包裹体，这个是人造水晶所没有的。
正常的水晶在生长时，多可以发现和柱形尖端棱线平行的生长纹（progress strains）。由于在地底、岩洞中的生长空间多狭窄，尤其在遇到地震时，或地壳变动时，甚至容易遭到其他矿石的挤压，常常会压迫产生不同的「晶面」。还有，当水晶还是在液态状的时候，常常也会包覆着其他的矿石、泥灰一起结晶成长，如金红石（稍后变成发晶）、火山泥灰（稍后变成幻影水晶）等等。所有的这些，都是「自然的一部分」，请不要视为「瑕疵」。
Crystals are categorised in general groups, for instance insulators, metals, semiconductors, and molecular solids. A single crystal of an insulator is often transparent and resembles a piece of glass. Metals are shiny Unless of course they've got rusted. Semiconductors are occasionally shiny and sometimes transparent but are in no way rusty. A lot of crystals may be categorised as only one kind of reliable, while some have intermediate behaviour. Cadmium sulfide (CdS) could be geared up in pure variety and is a wonderful insulator; when impurities are included to cadmium sulfide, it gets to be a fascinating semiconductor.
