人造水晶分为熔炼水晶与养殖晶：据水晶专家汪毅的阐述，随着水晶的价值提高，喜欢的人增多，水晶也引起了作伪者的兴趣，现阶段中国水晶市场常见的造假方法为：
Include to phrase list Increase to phrase checklist C2 [ U ] clear glass of pretty premium quality, ordinarily with its surface area Slice into delicate patterns
Additionally, there are many products that resemble crystals but read more are literally polycrystals. Polycrystals kind when microscopic crystals fuse with each other to variety a solid. These elements don't include requested lattices.
结晶�?When sea water is permitted to evaporate, salt crystals are deposited. 海水蒸发后，盐的结晶体就沉淀下来。
对任何宝石来说，颜色都是非常重要的，水晶也不例外。如果是水晶晶体是有颜色的，如粉水晶、黄水晶、紫水晶等，其颜色评价的最高标准则是明艳动人，不带有灰色、黑色、褐色等其他色调。如粉水晶，颜色以粉红为佳；紫水晶，要求颜色为鲜紫，纯净不发黑；黄水晶，要求颜色不含绿色、柠檬色调，以金橘色为佳。对于发晶来说，晶体的颜色也是很重要的。相同发丝的金发晶，晶体完全无色（白水晶）和晶体略偏茶色，肉眼的视觉观感也是有差别的，所以前者的价格会高于后者。
Hexagonal �?Characterised by four axes, three of which might be equivalent in size and intersect at 120 levels, by using a fourth axis perpendicular to one other a few.
Metallic Crystals: Metals usually form metallic crystals, exactly where a few of the valence electrons are totally free to move all through the lattice. Iron, such as, can sort various metallic crystals.
晶体 Silicon crystals developed within a laboratory transform mild into electrical Electrical power. 在实验室中长成的硅晶体可将光线转变为电能。
用手去触摸水晶，天然水晶通常温度要比人造水晶的要凉的多；用眼观察，天然水晶通常有棉絮状的包裹体，这个是人造水晶所没有的。
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。
