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。
A fundamental notion in crystal constructions will be the unit mobile. It's the smallest unit of quantity which allows identical cells to get arranged together to occupy all out there House. The geometrical basis of all crystals could be the lattice. A lattice might be viewed as a regular and infinite arrangement of details or atoms, in which Each and every level or atom has A similar encompassing setting.
4Without a crystal ball, It truly is unattainable to state where we are going to be upcoming calendar year.不用水晶球预卜未来，我们说不准明年处境如何呀。《牛津词典》
第一种是“全包裹体”，在水晶结晶的时候把这些物质包裹在晶体里面，这类包裹体所形成的各种景象，大多保持了水晶结晶时的原状，也就是说保存了几亿年的原状，极少受到自然环境的影响。
水胆水晶，包括气态，液态，固态，有时候可以同时多态并存，无色居多，个别情况下可见红色，绿色，黄色，蓝色，黑色等。
Lattices could possibly have a person lattice position per cell or more than one, yielding a total of fourteen Bravais crystal lattice website styles. Bravais lattices, named for physicist and crystallographer Auguste Bravais, explain the three-dimensional array made by a set of discrete factors.
时尚的收藏爱好者喜欢收藏天然水晶，却常常因为在市场上面对大量的合成水晶看走了眼。市面上的水晶：
Crystals are nothing at all in excess of an purchased arrangement of molecules or atoms. Crystals are available in many alternative shapes and sizes, and each one has different properties. The things they are created of determines how it's going to variety.
第三种是“皮景”，因某些其他的矿物与水晶体共生，或由于其他的物质侵蚀而依附于水晶表面，或者是水晶受自然环境的影响，在水晶表面出现蚀象，形成了一些景象或图案，这种景观存在于水晶表面。

地质学家目前为止对晶洞形成还没有广泛认同的理论，但相信晶洞可以在任何埋藏的空腔内形成。这些空腔可以是火成岩中的气泡、树根下的空穴，甚至动物挖的地洞。经过漫长时间，空腔的外壁变硬，溶解的矽酸盐或方解石沉积到内壁。再经过漫长的时间，缓慢渗入的矿物使得晶体在空腔内部结晶。
Orthorhombic: They're rhombic prisms and dipyramids that resemble tetragons but without having sq. cross-sections.
crystal, any good material through which the element atoms are organized inside of a definite pattern and whose surface regularity displays its inner symmetry.
