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。
杂质、裂纹越少越好。质地好的水晶制品，应看不到星点状、云雾状和絮状分布的气液包裹体或组成玉石的颗粒。有裂纹、斑点，则属于次品。

How Crystals Sort The process of forming a crystal is called crystallization. Crystallization typically happens each time a stable crystal grows from a liquid or Resolution.
你们都知道，拿起一个水晶棱镜，让一束阳光通过它，就会得到一个光谱，看起来就像一条连续的彩虹色带。

损伤是指水晶由于加工或不小心摔掉、碰撞等原因，人为造成的损坏。它可以是破口，也可以是凹坑等。
Q.4. What's the distinction between atomic composition and crystal construction? Ans. The main distinction between atomic framework and crystal structure lies in their definitions: atomic composition refers to how click here atoms are structured inside of a one molecule or possibly a cluster of molecules, While crystal construction fears the specific arrangement of atoms inside a solid substance.

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。
压电性：水晶晶体受到压力时会产生电荷；反之，受到电压作用时，晶体会产生频率很高的振动。水晶具有可使压力与电荷相互转移的性能，称压电性。
