Calcite crystals tend to be Employed in optical products, and in many cases the graphite in pencil lead are sheets of crystals that effectively split apart layer by layer to write down. Silica can kind silicate crystals which might be The idea for quartz, mica, olivine, and many other crystals and minerals.
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。
These advances incorporate unique buildings with programmable lattice symmetries and effectively-defined crystal patterns, responsive materials that leverage the intrinsic Homes of nucleic acids to govern structures on need, nanoparticle superlattices developed epitaxially from surfaces and colloidal crystals offering insights into mild–matter interactions. Hunting forward, we challenge the Neighborhood to leverage the extraordinary structural Command afforded by crystal engineering with DNA to synthesize courses of practical materials check here that press over and above what has become possible with Normally occurring crystalline elements or People produced by far more typical approaches.
看原料：选料精良的水晶制品，应看不到胶口及棉絮；质地纯净、光润、晶莹为好。
看抛光：抛光的好坏直接影响到水晶制品的身价。抛光分为软抛光与硬抛光。
They may sooner or later generate a wonderful tiny uniform cluster of atoms, This really is the whole process of expanding crystals. The more they can come collectively, the more of the development are going to be noticeable towards the naked eye. Scientists can figure out what mineral They may be investigating by how the crystals type.

There's a similar directive about crystal glass which differentiates in between whole lead crystal, direct crystal and crystal.
仿制钛晶树水晶：钛晶是水晶里价格最昂贵的，造假者当然也不会放过这么好的产品。天然的环境下，在水晶里能生长个像树一样的钛晶，完全是可能的，只是这样的货很少，那我们的造假专家是如何做的呢，白水晶底下打个洞，激光打点成板状的钛晶进去，就这样这块水晶的身价就能飙升几十倍。往往有的钛晶戒面，会采用将钛晶部位割成板状，与圆面的水晶粘合的方法来制作。
A crystal system refers back to the classification of crystals according to the geometric arrangement and symmetry in their lattice structures. You can find 7 main crystal techniques:
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。
Orthorhombic: These are generally rhombic prisms and dipyramids that resemble tetragons but with out sq. cross-sections.
水晶饰品越来越受到人们的喜爱。中国、日本、韩国、美国等国家的人们还对水晶球情有独钟，喜欢将它们摆在家里或办公室里，认为水晶球有灵性，能保平安，带来财运。不过天然水晶不像看起来那么晶莹剔透，它也有瑕疵，我们在选购饰品的时候要注意。此外，我们还要掌握水晶的评价依据、选购方法，这样可以帮助我们在琳琅满目的水晶饰品中选到心仪的水晶。
水晶的价值根据品质、块体的大小、美感和产量多少的不同相差较大。遇到好的天然水晶要敢于下手，但好的水晶一般大家都想得到，值与不值，就要看经验了。由于天然水晶的开采和制作原因，没有瑕疵的水晶很难得到，纯净的饰品要达到与合成水晶媲美的品质，实在是很难得。另外，由于水晶的特性，在佩戴过程中，也会改变其等级，比如因为某种原因，有可能会逐渐产生较大裂纹。
