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。

晶及其石英岩类玉石是中低档宝玉石，虽比不上钻石、红蓝宝石的高贵，但在加工中如果构思巧妙而且加工精细，同样具有很高的价值。如中国传统的玛瑙“虾盘”、“龙盘”、“水漫金山�?水胆玛瑙摆件)都被誉为国家级宝玉石。
Most reliable components found in nature exist in polycrystalline sort as an alternative to as an individual crystal. They are actually made up of numerous grains (little crystals) packed alongside one another to fill all Place. Each specific grain has another orientation than its neighbours. Though long-assortment buy exists in just 1 grain, with the boundary involving grains, the buying adjustments course. A standard piece of iron or copper (Cu) is polycrystalline.
条痕颜色：无色。矿物粉末的颜色叫条痕。它可以消除假色，减弱他色，保留自色，是比矿物的颜色更为可靠的鉴定特征之一。
They're going to ultimately produce a nice tiny uniform cluster of atoms, That is the entire process of developing crystals. The greater they will appear with each other, the greater of a development will be noticeable into the naked eye. Scientists can ascertain what mineral They're considering by how the crystals form.
Springer Mother nature stays neutral regarding jurisdictional claims in released maps and institutional affiliations.
The elements are uncovered in a variety of crystal packing arrangements. The commonest lattice constructions for metals are People acquired by stacking the atomic spheres into the most compact arrangement.

水晶的价值还与块体大小有关，同样的颜色和净度级别，块越大越难得。有时候质量级别虽然低一些，但块体够大，也可能价格高于高级别的小晶体
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。
crystal Alteration is variable: absent in many crystals, in Many others developing dense sericite aggregates which can present some recrystallization results to produce coarser-grained white mica. From the Cambridge English Corpus The tridymite crystals are rectangular or wedge-formed and are occasionally organized in aggregates. Through the Cambridge English Corpus Moreover, haloarchaeal cells were embedded inside of salt crystals below laboratory problems and subsequently analysed by light-weight microscopy. Through the Cambridge English Corpus The white clouds (normally sparse) were also widely considered to be currently being composed of very small crystals of drinking water ice, relatively like cirrus within our atmosphere. Through the Cambridge English Corpus These are present in evaporite salt lakes and might be trapped in salt crystals throughout evaporation. From the Cambridge English Corpus read more Thus, the cells (organelles and membranes) are destroyed mechanically by ice crystals, leading to Demise through mobile lysis. In the Cambridge English Corpus The crystals were being used in the very first or next orders of reflection. Within the Cambridge English Corpus Within our 8xperiments, the crystals ended up cubes using a foundation spot of 8 e mm. In the Cambridge English Corpus Vibration-assisted intermolecular hydrogen tunneling in photoreactive doped molecular crystals : outcome of temperature and stress.
