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。
23Sometimes, on the other hand, the crystal type of the silicate inclusions is noticed to resemble extra intently The interior composition 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

. These four constructions comprise almost all of the binary crystals with equivalent figures of cations and anions.
, has exactly the same framework, but There's two selections for selecting the holes the atoms will occupy. The 3rd layer is often placed around the atoms of the main layer, generating an alternate layer sequence A
对任何宝石来说，颜色都是非常重要的，水晶也不例外。如果是水晶晶体是有颜色的，如粉水晶、黄水晶、紫水晶等，其颜色评价的最高标准则是明艳动人，不带有灰色、黑色、褐色等其他色调。如粉水晶，颜色以粉红为佳；紫水晶，要求颜色为鲜紫，纯净不发黑；黄水晶，要求颜色不含绿色、柠檬色调，以金橘色为佳。对于发晶来说，晶体的颜色也是很重要的。相同发丝的金发晶，晶体完全无色（白水晶）和晶体略偏茶色，肉眼的视觉观感也是有差别的，所以前者的价格会高于后者。
The weather are identified in a variety of crystal packing preparations. The most typical lattice constructions for metals are those received by stacking the atomic spheres into by far the most compact arrangement.

Solids which have short-vary buy but lack very long-range purchase are referred to as amorphous. Practically any check here content could be created amorphous by quick solidification from your soften (molten state). This ailment is unstable, as well as the sound will crystallize in time. Should the timescale for crystallization is a long time, then the amorphous point out appears secure.
⑥、丝印：水晶表面附有不同的色料进行效果处理，颜色层面较厚，着力后方可脱落。

This Assessment chronicles more than 20 years of research into making a genetic code for crystal engineering. As an alternative to directing biological processes, this code works by using synthetic kinds of DNA to programme the assembly of nanoparticles and microparticles into 1D, second and 3D crystalline architectures, in which nearly each and every element of the resultant structures may be systematically controlled. Inside this conceptual framework, the structural and purposeful improvements are described in an effort to outline the existing level of sophistication and to forecast future directions from the System.
Tetragonal �?Characterized by three mutually perpendicular axes, two of that are equal in size, while the third is longer or shorter and perpendicular to another two.
