看颜色：即使在同一种类的水晶中，它的不同部位的纹理、色泽也各式各有千秋。属于单色的，要色度均匀；在同一块水晶上有深浅的，则要求其色调纹路美观大方。

对水晶进行评价主要依据其颜色、透明度、大小、净度、特殊图案及是否有光学效应等方面。以颜色纯正，浓度较高，内部无瑕为好。种类上紫晶最贵，其次为黄晶、烟晶、无色水晶和芙蓉石。有特殊光学效应的水晶的价格更高。

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。

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（expansion 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」。

水晶的价值根据品质、块体的大小、美感和产量多少的不同相差较大。遇到好的天然水晶要敢于下手，但好的水晶一般大家都想得到，值与不值，就要看经验了。由于天然水晶的开采和制作原因，没有瑕疵的水晶很难得到，纯净的饰品要达到与合成水晶媲美的品质，实在是很难得。另外，由于水晶的特性，在佩戴过程中，也会改变其等级，比如因为某种原因，有可能会逐渐产生较大裂纹。
