A sound is crystalline if it's lengthy-vary order. When the positions of the atom and its neighbours are regarded at one particular position, the place of each and every atom is known specifically all over the crystal. Most liquids deficiency extended-vary purchase, Though many have shorter-assortment purchase. Shorter variety is defined as the initial- or next-closest neighbours of the atom. In lots of liquids the first-neighbour atoms are organized in the exact same structure as in the corresponding stable period.
12He tried out all over again in many other metropolitan areas and succeeded with Crystal Caramels.他又在其他几个城市再次尝试，并成功制出了水晶焦糖。
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。
③次生包裹体：指主体水晶形成后，由于环境的变化使得主晶周围的一些物质沿裂隙进入到其内部而形成的包裹体。形成的原因有出熔作用、裂隙的结晶化、以及放射性元素破坏的作用等。水晶典型的次生包裹体有胶花水晶中的氧化铁充填物等。
Crystalline structure is characterized by a geometrical, repeating sample of symmetric molecular composition. The arrangement of atoms varieties these ordered, repeating designs.
They will sooner or later generate a nice very little uniform cluster of atoms, That is the entire process of expanding crystals. The greater they could appear alongside one another, the greater of a formation will be obvious to here the bare eye. Researchers can ascertain what mineral they are checking out by how the crystals sort.

⑥、丝印：水晶表面附有不同的色料进行效果处理，颜色层面较厚，着力后方可脱落。
正常的水晶在生长时，多可以发现和柱形尖端棱线平行的生长纹（growth strains）。由于在地底、岩洞中的生长空间多狭窄，尤其在遇到地震时，或地壳变动时，甚至容易遭到其他矿石的挤压，常常会压迫产生不同的「晶面」。还有，当水晶还是在液态状的时候，常常也会包覆着其他的矿石、泥灰一起结晶成长，如金红石（稍后变成发晶）、火山泥灰（稍后变成幻影水晶）等等。所有的这些，都是「自然的一部分」，请不要视为「瑕疵」。
