A good is crystalline if it's lengthy-vary get. Once the positions of the atom and its neighbours are recognized at one particular position, the position of every atom is known exactly through the crystal. Most liquids lack very long-variety order, although several have limited-range order. Limited array is outlined as the main- or second-nearest neighbours of the atom. In several liquids the very first-neighbour atoms are organized in exactly the same structure as in the corresponding stable stage.
Crystals are attractive rock formations which have stunned human beings for Countless years. They're used for a lot of different things, not only for decoration. A lot of the first radios at any time invented utilised crystals to transmit the radio waves. Some instruments, like quartz watches and laser crystals, use Unique Houses and harmonic abilities of crystals to make hugely precise measurements and adjustments.
一般而言，紫晶和黄晶是水晶中价值较高的品种。两者进一步的分级是据其颜色的深浅，颜色较深的为A级，稍浅的为B级。一般颜色较深的价格高，但要以不深暗为标准。颜色包括两种，一种是水晶本身的颜色，另一种是内部包裹体的颜色。水晶本身的颜色要艳丽、纯正，分布要均匀，不能太深或太浅，如澳州玉、蓝玉髓、紫晶、黄水晶，其价格就高。无色的水晶内含包裹体的颜色艳丽，其价格也高，如钛晶、绿幽灵、红兔毛。紫水晶一般以稍有云状物、颜色深紫、晶体通透的为上品。
第一种是“全包裹体”，在水晶结晶的时候把这些物质包裹在晶体里面，这类包裹体所形成的各种景象，大多保持了水晶结晶时的原状，也就是说保存了几亿年的原状，极少受到自然环境的影响。
断口：贝壳状。断口也叫破口。它是指矿物被打击后产生不规则的破裂，破裂裂面凹凸不平称为断口。根据断口的形状可分为贝壳状和锯齿状。
Lattices can have one lattice point for each cell or multiple, yielding a complete of fourteen Bravais crystal lattice types. Bravais lattices, named for physicist and crystallographer Auguste Bravais, describe the three-dimensional array created by a set of discrete factors.
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。

Numerous crystals behave like butter in that they're tough at reduced temperatures but tender at higher temperatures. They are termed solids in the slightest degree temperatures underneath their melting level. A possible definition of the good is surely an object that retains its shape if still left undisturbed. The pertinent problem is how much time the thing keeps its condition. A highly viscous fluid retains its shape for an hour but not a calendar year. A sound ought to keep its shape longer than that.
看文化：水晶里面的包裹体象形，能与文化、宗教及历史有所牵连的话，价格往往会比水晶本身的价值高出几倍甚至几百倍。

Crystal Lattices There are 7 methods of crystal constructions, that are also referred to as lattices or Room lattices:
crystal, any sound product where the ingredient atoms are arranged within a definite sample and whose area regularity demonstrates its inner symmetry.
The C60 molecules, also called buckyballs, are rather solid and Just about incompressible. Crystals are formed this more info sort of the balls are organized within an fcc lattice which has a one particular-nanometre spacing between the centres of adjacent balls. The very similar C70 molecule has the shape of the rugby ball; C70 molecules also sort an fcc crystal when stacked together. The good fullerenes form molecular crystals, with weak binding—supplied by van der Waals interactions—between the molecules.
