17These rings are indicative in the crystal structure of nickel and might be spelled out 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。

无色水晶以晶莹美丽、洁净透明着称。衡量无色水晶主要看它的纯度，越纯、越透明越好。干净的、无瑕疵的、杂质少的价值就高。无色的水晶如果很脏，就没有利用价值。

对水晶进行评价主要依据其颜色、透明度、大小、净度、特殊图案及是否有光学效应等方面。以颜色纯正，浓度较高，内部无瑕为好。种类上紫晶最贵，其次为黄晶、烟晶、无色水晶和芙蓉石。有特殊光学效应的水晶的价格更高。

第二种是“半包裹体”，在水晶结晶以后，由于受到地球引力的影响而产生的裂隙，晶体外的一些物质通过水晶的裂隙渗透到水晶内部，一部分包裹于水晶之中另一部分露于水晶之外。我们可以看到物质渗进水晶的裂迹，常被称为“通道”，这种包裹体所形成的景象相对地较受自然环境和时间的影响，相应的价值也比较�?。

水晶内部有多种矿物包裹体，形成的各种景观可以肉眼观测，这样的水晶就是包裹体水晶观赏石。由于水晶本身就是宝石，因此人们称誉包裹体水晶为“宝石级的观赏石”。包裹体水晶观赏石都具有独特性，具有极高欣赏和收藏价值。

Q.four. What is the difference between atomic composition and crystal structure? Ans. The main difference between atomic composition and crystal construction lies in their definitions: atomic framework refers read more to how atoms are organized in a one molecule or perhaps a cluster of molecules, Whilst crystal framework considerations the precise arrangement of atoms inside of a stable substance.

Crystals with evident flat faces are termed euhedral crystals, when Those people lacking described faces are called anhedral crystals. Crystals consisting of ordered arrays of atoms that aren't generally periodic are identified as quasicrystals.

. The next layer is shaded in the figure. It's exactly the same plane-triangular composition; the atoms sit in the holes fashioned by the 1st layer. The 1st layer has two equivalent sets of holes, but the atoms of the 2nd layer can occupy just one established. The third layer, labeled C

Orthorhombic: These are typically rhombic prisms and dipyramids that resemble tetragons but without having sq. cross-sections.

⑨、喷砂：立体感弱，较平整，无凹凸感，机器雕刻文字、图形等后进行效果处理。成本低制作快。

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。
