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, nonetheless, the crystal form of the silicate inclusions is observed to resemble additional carefully The inner construction 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。
A simple notion in crystal buildings is definitely the device mobile. It's the smallest device of quantity that permits similar cells to get stacked with each other to fill all Place. By repeating the pattern from the unit cell time and again in all directions, the entire crystal lattice might be manufactured. A dice is The only example of a unit mobile. Two other examples are revealed in Determine 1. The first will be the unit mobile for your encounter-centred cubic lattice, and the second is for a system-centred cubic lattice. These structures are spelled out in the following paragraphs.
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。
水胆水晶，包括气态，液态，固态，有时候可以同时多态并存，无色居多，个别情况下可见红色，绿色，黄色，蓝色，黑色等。
These examples are from corpora and from resources on the net. Any viewpoints within the illustrations never represent the view in the Cambridge Dictionary editors more info or of Cambridge University Press or its licensors.
Crystals search one of a kind from a number of other rocks and minerals, but �?barring several Unique scenarios �?nearly all minerals cover a crystalline structure underneath the surface area.
11I carefully opened the deal and located a crystal bell within.我小心地打开包裹，发现里面有一个水晶钟。
第三种是“皮景”，因某些其他的矿物与水晶体共生，或由于其他的物质侵蚀而依附于水晶表面，或者是水晶受自然环境的影响，在水晶表面出现蚀象，形成了一些景象或图案，这种景观存在于水晶表面。
⑤化学稳定�?非常好，在常温下仅溶解于氢氟酸，不溶解于其它各类酸、碱。在高温高压条件下可溶解于碳酸钠溶液中。
地质学家目前为止对晶洞形成还没有广泛认同的理论，但相信晶洞可以在任何埋藏的空腔内形成。这些空腔可以是火成岩中的气泡、树根下的空穴，甚至动物挖的地洞。经过漫长时间，空腔的外壁变硬，溶解的矽酸盐或方解石沉积到内壁。再经过漫长的时间，缓慢渗入的矿物使得晶体在空腔内部结晶。
Crystallography will be the examine of crystals, and it deals with almost everything from great geometric designs to seemingly random conglomerations of particles and minerals.
在透明的水晶中，隐裂纹呈亮晶晶的片状，有时还会有晕彩效应。这些裂纹是水晶在生长过程中，遇到外力挤压而在内部产生的一些隐形裂纹，隐裂纹在芙蓉石、紫水晶、白水晶球及白水晶柱中都很常见。有的裂纹后来被物质填充，形成愈合的裂纹，也就是原来的裂纹又长住了。这种裂纹对水晶的影响相对要小一些。
Tetragonal �?Characterised by 3 mutually perpendicular axes, two of which happen to be equal in duration, even though the 3rd is extended or shorter and perpendicular to the other two.
