A solid is crystalline if it's extended-variety get. Once the positions of an atom and its neighbours are recognised at one position, the position of each atom is thought exactly throughout the crystal. Most liquids absence lengthy-assortment get, although numerous have short-selection order. Shorter selection is outlined as the 1st- or 2nd-closest neighbours of the atom. In several liquids the initial-neighbour atoms are arranged in the exact same construction as inside the corresponding reliable stage.
Bismuth (Bi) appears being a metallic, but the quantity of electrons accessible for electrical conduction is similar to that of semiconductors. In truth, bismuth is known as a semimetal. Molecular solids tend to be crystals fashioned from molecules or polymers. They are often insulating, semiconducting, or metallic, with regards to the variety of molecules within the crystal. New molecules are repeatedly getting synthesized, and several are made into crystals. The number of distinctive crystals is big.
看做工：水晶制品加工过程分为两种，即磨工和雕工。如水晶项链、手链、耳环等属于研磨品；观音像、内画鼻烟壶等属于雕刻品。

根据美国已经了解的情况，统计局的专家和其他人口统计学家在他们的视野中提供了一个不可抗拒的水晶球。
, has precisely the same composition, but There's two alternatives for choosing the holes that the atoms will occupy. The 3rd layer could be positioned in website excess of the atoms of the very first layer, creating an alternate layer sequence A
水晶的评价标准和高端宝石有所不同。多数高端宝石把颜色放在评价的第一位，而对水晶来说，颜色和净度（水晶行业称作晶体）是近乎同等重要的因素：
如果水晶内部杂质中有传说中人物的造型，如佛、星座、生肖等价值可能要高于同等颜色和净度的水晶。
包裹体常见有固相、固液气三相组合、空洞以及双晶、色带等。水晶中典型的同生包裹体有自形的锐钛矿、气液两相包体等。
幽灵水晶，分绿幽灵，红幽灵，白幽灵等，主要组成为绿泥石，其中绿幽灵属于珍贵品种。

Molecular Crystals: Total molecules are bonded to each other within an organized method. An excellent example is really a sugar crystal, which has sucrose molecules.
⑨、喷砂：立体感弱，较平整，无凹凸感，机器雕刻文字、图形等后进行效果处理。成本低制作快。
对于紫水晶黄水晶这样的单色水晶，通常要观察它的二色性，即使是最顶级的紫水晶黄水晶也是有色差的，通过这个方法可以鉴别是否加色。
