天然的水晶一般都会有絮状（绵绺），也就是大家俗称的瑕疵，这是液体水落石出和二氧化碳的小孔穴，而人工合成的水晶就不会有这样的特征。
按照透明度指标，水晶越透明，价格越高，好的透明的水晶加工出的成品晶莹剔透、光辉耀眼。透明度高的水晶能提升颜色的艳丽，否则显得呆板无灵性。光学水晶要求全透明、无双晶、无杂质。工艺水晶要求透明、少裂、少瑕疵。熔炼水晶要求透明，可有较多裂纹。三者价值依次降低，熔炼水晶只能作为熔炼水晶玻璃的原料。在工艺水晶中，晶体较大的，可用来做水晶眼镜和雕刻高档工艺品，因而价格较高。
结晶的形状非常细小，需要用显微镜才能看得清楚，外观上看起来是平滑、块状。常见最多的是各式玛瑙
养殖晶：养殖晶是指，用天然水晶做种子，然后赋予天然水晶生长的高压条件，养殖器中有富含二氧化硅的分子。然后二氧化硅分子围绕天然水晶种生长，这样的水晶成分（分子式）与天然水晶是一摸一样的，唯一有差别的是，这样的水晶磁场作用没有天然水晶强。
断口：贝壳状。断口也叫破口。它是指矿物被打击后产生不规则的破裂，破裂裂面凹凸不平称为断口。根据断口的形状可分为贝壳状和锯齿状。
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。
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。
The weather are found in a variety of crystal packing preparations. The commonest lattice buildings for metals are All those acquired by stacking the atomic spheres into by far the most compact arrangement.
Many crystals behave like butter in that they're challenging at minimal temperatures but gentle at increased temperatures. These are known as solids in the slightest degree temperatures under their melting position. A achievable definition of a strong is definitely an object that retains its form if still left undisturbed. The pertinent issue is how much time the thing retains its shape. A remarkably viscous fluid retains its shape for an hour or so but not a year. A sound ought to maintain its form longer than that.
幽灵水晶，分绿幽灵，红幽灵，白幽灵等，主要组成为绿泥石，其中绿幽灵属于珍贵品种。
Solitary crystals of metals are delicate and malleable, while polycrystalline metals are tougher and more robust and tend to be more helpful industrially. Most polycrystalline supplies might be made into large one crystals just after extended warmth remedy. Before blacksmiths would heat a piece of metal to make it malleable: warmth will make a few grains grow large by incorporating lesser types. The smiths would bend the softened steel into condition and after that pound it awhile; the pounding would allow it to be polycrystalline once again, increasing its toughness.
Crystallography could be the analyze of crystals, and it discounts with every little thing from great geometric designs to seemingly random conglomerations of particles and minerals.
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。
