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。

Crystals are wonderful rock formations that have shocked human beings for thousands of a long time. They are really used for several different things, not just for decoration. Most of the to start with radios at any time invented utilized crystals to transmit the radio waves. Some instruments, like quartz watches and laser crystals, use Exclusive properties and harmonic abilities of crystals to produce remarkably exact measurements and adjustments.

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。

If you want to see how crystals are formed, you are able to perform a little venture in the very personal kitchen and find out the development on the crystals come about together with your own eyes . This can be carried out by putting a small level of desk salt into some regular faucet water, wait around 24 several hours, and you will see awesome cubed formations. This comes about as the water is evaporating, which leads to the atoms which make up the salt (the mineral) and also the water to come closer together.

. These four buildings comprise a lot of the binary crystals with equal figures of cations and anions.

, has the same composition, but There's two alternatives for choosing the holes which the atoms will occupy. The third layer might be positioned over the atoms of the initial layer, making an alternate layer sequence A

石英：《广雅》称水晶叫石英，色白如莹者又叫白。为附的异形字。司马相如《子虚赋》就�?�?雌黄�?�?之句。苏林解释：�?�?，白石英�?”。

②固体包裹体：指呈固态相存在包裹体，多因岩浆、热液、变质作用等形成的早期结晶物被水晶捕获而形成。

Crystals are frequently seen as a thing of huge attractiveness, and so they are generally employed with diamonds or other stones to create parts of jewellery. The vast majority of crystals now are person-produced in laboratories.

The definition of a stable seems evident; a solid is mostly thought of as remaining really hard and organization. On inspection, on the other hand, the definition will become a lot less clear-cut. A dice of butter, as an example, is difficult after becoming stored in the fridge and is particularly Evidently a reliable. Following remaining over the kitchen counter for on a daily basis, the same cube gets rather smooth, and it is actually unclear If your butter must still be deemed a sound.

. The 2nd layer is shaded inside the determine. It's got the identical aircraft-triangular construction; the atoms sit read more while in the holes fashioned by the primary layer. The very first layer has two equivalent sets of holes, however the atoms of the next layer can occupy just one set. The third layer, labeled C

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

14For example, We now have Quartz crystal clocks and watches correct to within a person moment a yr.例如，我们使用的每年误差不超过one分钟的石英水晶钟表和手表。

Binary crystals are found in a lot of buildings. Some pairs of components kind more than one structure. At room temperature, cadmium sulfide may crystallize possibly during the zinc blende or wurtzite construction. Alumina also has two probable structures at place temperature, α-alumina (corundum) and β-alumina. Other binary crystals exhibit distinctive buildings at distinct temperatures. Among the many most complicated crystals are These of silicon dioxide (SiO2), which has seven distinct structures at different temperatures and pressures; the most common of such constructions is quartz.
