17These rings are indicative from the crystal structure of nickel and will be spelled out only by invoking wavelike Attributes of sunshine.这些光圈表明了了镍的晶体结构，而且只能通过光线中波的特征来解释。

A basic plan in crystal structures is the device cell. It is the smallest unit of quantity which allows equivalent cells being organized together to occupy all accessible House. The geometrical basis of all crystals is definitely the lattice. A lattice is often viewed as a daily and infinite arrangement of details or atoms, where by Just about every point or atom has The same surrounding natural environment.

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。

养殖晶：养殖晶是指，用天然水晶做种子，然后赋予天然水晶生长的高压条件，养殖器中有富含二氧化硅的分子。然后二氧化硅分子围绕天然水晶种生长，这样的水晶成分（分子式）与天然水晶是一摸一样的，唯一有差别的是，这样的水晶磁场作用没有天然水晶强。

2She was putting on a strand of crystal beads.她戴着一串水晶珠子。《柯林斯英汉双解大词典》

发晶，包括钛晶，铜顺发，绿发晶，黑发晶，银发晶，杂色发晶，其中钛晶最珍贵，少数钛晶价值可比钻石，红宝石和蓝宝石以及祖母绿。

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。

Crystals are nothing more than an purchased arrangement of molecules or atoms. Crystals are available in many different styles and sizes, and each has distinctive attributes. What they are created of decides how it is going to kind.

In the meantime, to be certain ongoing help, we have been displaying the location without having kinds and JavaScript.

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。

看孔眼：对于缀穿水晶制品（如项链、手链、佛珠），要看孔眼是否平直，孔的粗细是否均匀，有无细小裂纹。孔壁必须清澈透明，无“白痕”。

The arrangement of the atom’s electrons decides its chemical Attributes. The properties of solids are often predictable in the Homes in their constituent atoms and molecules, and the different shell constructions of atoms are for that reason answerable for the variety of solids.

Crystals are categorised normally types, such as insulators, metals, semiconductors, and molecular solids. One crystal of an insulator is often transparent and resembles a piece of glass. Metals are shiny Until they've rusted. Semiconductors are occasionally shiny and from time to time clear but are hardly ever rusty. Quite a few crystals is often categorized as just one sort of stable, while some have intermediate conduct. Cadmium sulfide (CdS) may be ready in pure kind website and is a superb insulator; when impurities are added to cadmium sulfide, it becomes a fascinating semiconductor.
