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。

They are going to finally create a wonderful minor uniform cluster of atoms, This is often the entire process of developing crystals. The greater they can arrive collectively, the greater of the formation might be obvious to your naked eye. Experts can figure out what mineral These are checking out by how the crystals sort.
