水晶表面坑洼的地方，有的深，有的浅，这是水晶在成长过程中自然形成的，并非是人为造成的损伤。缺陷位置本来包有其他矿物晶体，由于包裹体和水晶结合部位的结合力不强，当表面抛光时，矿体脱落，留下空位。这种缺陷在绿幽灵、钛晶、金发晶上都比较常见。
A fundamental strategy in crystal buildings is definitely the device cell. It's the smallest unit of quantity which allows similar cells to get arranged alongside one another to occupy all available space. The geometrical foundation of all crystals is definitely the lattice. A lattice might be considered as an everyday and infinite arrangement of points or atoms, the place each level or atom has A similar encompassing surroundings.
These advancements incorporate exotic structures with programmable lattice symmetries and properly-described crystal patterns, responsive components that leverage the intrinsic Homes of nucleic acids to manipulate constructions on demand from customers, nanoparticle superlattices developed epitaxially from surfaces and colloidal crystals that supply insights into mild–make a difference interactions. Seeking ahead, we obstacle the Neighborhood to leverage the extraordinary structural Regulate afforded by crystal engineering with DNA to synthesize courses of purposeful products that press over and above what has long been achievable with Obviously taking place crystalline products or People produced by far more regular procedures.
Tetragonal: These crystals type prisms and double pyramids. The structure is like a cubic crystal, except a person axis is longer than another.
Crystalline composition is characterized by a geometrical, repeating pattern of symmetric molecular construction. The arrangement of atoms kinds these requested, repeating designs.
Learn how the shape in the crystals determine different minerals into familiesMinerals crystallize In line website with one of seven motifs, generally known as crystal devices.
光泽：玻璃光泽。断口处为油脂光泽。光泽，指宝石表面对光线反射的一种光学性质。观察水晶的光泽，可用手握着它，以灯光或窗户投进来的光线看表面反射，透明水晶亮度与光泽强弱有关。
发晶：无色、浅黄、浅褐等，可因含金红石常呈金黄、褐红等色，含电气石常呈灰黑色；含阳起石而呈灰绿色。
Crystals are sometimes viewed as something of immense attractiveness, and so they are commonly applied with diamonds or other stones for making pieces of jewellery. Many crystals now are gentleman-built in laboratories.
颜色：无色，浅至深的紫色，浅黄、中至深黄色，浅至深褐、棕色，绿至黄绿色，浅至中粉红。
15The trick to a superb thermoelectric substance can be a crystal framework by which electrons can circulation freely.制造一种好的热电材料的关键是，需要一种电子可以自由流动的晶体结构。
水晶形成后由于外力作用或某种人为原因使水晶产生大的裂隙或裂纹，这种裂纹有大有小，对水晶的影响也有大小之分。
This Overview chronicles around two decades of research into creating a genetic code for crystal engineering. Rather then directing Organic procedures, this code uses artificial sorts of DNA to programme the assembly of nanoparticles and microparticles into 1D, second and 3D crystalline architectures, in which just about each facet of the resultant constructions can be systematically controlled. In this conceptual framework, the structural and purposeful improvements are described in order to define the present standard of sophistication also to predict foreseeable future directions of your System.
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。
