Not all crystals are Similarly crystalline. There will often be impurities, and also the ionic & covalent among molecules can produce vastly different constructions outside of precisely the same materials. An excellent example of this are diamonds and graphene.

发晶的价值取决于发的颜色、罕见性及大小,一般是发色鲜艳、块度大的价格高。水胆水晶的价值主要取决于水胆及晶体的大小、透明度的高低。如果水胆较大并有一定形态,便可加工成较为珍贵的工艺品。另外水胆中的水也有一定的科学研究价值,通过它们可了解几百万年前地球上水的成分及变化。
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。
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。
无色水晶与无色长石因折射率和密度十分接近故较难区分。主要方法是放大检查。长石有两组极完全解理,显微镜下可见两组解理相交而成的“娱蛤状”包裹体或细直的纹理,而水晶则无解理发育,仅有时可见断续不规则的裂理。
⑩、雷射内雕:以计算机辅助激光设备在水晶对象中进行三维图案的成型,艺术效果好,可以任意表达各类图案,图形,达到逼真效果
发晶:无色、浅黄、浅褐等,可因含金红石常呈金黄、褐红等色,含电气石常呈灰黑色;含阳起石而呈灰绿色。
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。
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。
There are just a few various device-cell designs, so many alternative crystals share only one device-mobile variety. A vital attribute of a unit mobile is the quantity of atoms it includes. The overall range of atoms in the entire crystal would be the range in Every cell multiplied by the volume of unit cells. Copper and aluminum (Al) Every single have one atom for every device mobile, though zinc (Zn) and sodium chloride have two. Most crystals have only some atoms for every unit mobile, but there are some exceptions. Crystals of polymers, as an example, have Countless atoms in Every single unit cell.

⑥白色的包裹体有蚀变的绿泥石、云母、愈合裂隙、水晶、方解石、透闪石等。
