水晶表面坑洼的地方，有的深，有的浅，这是水晶在成长过程中自然形成的，并非是人为造成的损伤。缺陷位置本来包有其他矿物晶体，由于包裹体和水晶结合部位的结合力不强，当表面抛光时，矿体脱落，留下空位。这种缺陷在绿幽灵、钛晶、金发晶上都比较常见。

广义的包裹体是指宝石内部含有的与主晶宝石化学成分、物理性质等不同的物质。

⑥、丝印：水晶表面附有不同的色料进行效果处理，颜色层面较厚，着力后方可脱落。

隐晶类水晶外观是一块块的，不是成六角水晶簇状，但他们却也是属六方晶系的。但我们不能以肉眼观察到他们的六角形结晶，因为结晶的体积极为细小，需以显微镜协助下才能看到六角开结晶。而此类水晶非常平滑，因为结晶之间有“水化硅石”填补，玛瑙便属于此类。

⑤、打孔：是在水晶成品未完成前，根据其所需打孔之尺寸及位置，以钻头加工，如制表件、笔筒、瓶孔等。

矿物成分：针铁矿、赤铁矿、金红石、磁铁矿、电气石、石榴石、云母、绿泥石等形成了包裹体水晶，如发晶、钛晶、绿幽灵等，发晶中则含有肉眼可见的似头发状的针状矿物的包裹体形成。含锰和铁者称紫水晶；含铁�?；呈金黄色或柠檬�?)称黄水晶；含锰和钛呈玫瑰色者称蔷薇石英，即粉水晶；烟色者称烟水晶；褐色者称茶晶；黑色透明者称为墨晶。
