17These rings are indicative from the crystal construction of nickel and might be stated only by invoking wavelike Homes of light.这些光圈表明了了镍的晶体结构，而且只能通过光线中波的特征来解释。
23Sometimes, even so, the crystal kind of the silicate inclusions is observed to resemble far more closely The inner framework of diamond than that of other silicate minerals.然而，有时观察到硅酸盐包裹体的晶体形态比其他硅酸盐矿物更接近金刚石的内部结构。
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
Huge crystals of diamond are useful gemstones. The crystal has other interesting Qualities; it has the very best seem velocity of any good and is the greatest conductor of warmth. Aside from diamond, one other prevalent method of carbon is graphite, which happens to be a layered materials. Each and every carbon atom has a few coplanar close to neighbours, forming an arrangement called the honeycomb lattice. A few-dimensional graphite crystals are obtained by stacking similar levels.

⑧、雕刻：立体感强，工艺高，做工精细，成本高。分手工雕刻图形、机器雕刻文字。
水晶与高档宝石的净度要求有很大不同。高档宝石稀少罕见，所以一般人们普遍对高档宝石的净度不会过于苛求。而水晶的产量着实大得惊人，所以通常人们会要求水晶净度越高越好，尽量避免有较明显的内含物的水晶。

水晶观赏石是天然水晶中最具代表的作品，具有其他宝石都不具备的观赏性。不论是玉石翡翠还是都要经过雕琢后次能体现他的价值，而水晶观赏石只需要将表面进行抛光，即展现出晶体内所包裹的物质，直接欣赏原汁原味的水晶石。
