Not all crystals are Similarly crystalline. There are often impurities, as well as ionic & covalent involving molecules can produce vastly different buildings out of the same material. A great illustration of this are diamonds and graphene.
23Sometimes, on the other hand, the crystal type of the silicate inclusions is noticed to resemble much more closely The interior structure of diamond than that of other silicate minerals.然而，有时观察到硅酸盐包裹体的晶体形态比其他硅酸盐矿物更接近金刚石的内部结构。
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。
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。
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。
根据包裹体和主晶宝石之间形成的先后关系可将水晶的包裹体划分以下三种类�?
Ionic Crystals: Electrostatic forces type ionic bonds. A basic example can be a halite or salt crystal.
第三种是“皮景”，因某些其他的矿物与水晶体共生，或由于其他的物质侵蚀而依附于水晶表面，或者是水晶受自然环境的影响，在水晶表面出现蚀象，形成了一些景象或图案，这种景观存在于水晶表面。
22Working from what The united states by now appreciates about itself, the bureau's experts and also other demographers supply an irresistible, if clouded, crystal ball among their visions.
16I opened the box and noticed a bit of crystal snowflake and a greeting card with "Delighted Birthday" inside the blank paper.我打开盒子并看见在白纸中有一片水晶雪花和一张写着“生日快乐”的贺卡。
国家还并未给天然水晶提供一个等级划分的具体标准，水晶品种繁杂，每一品种都有他不同的评判标准。

Binary crystals are present in a lot of buildings. Some pairs of features variety multiple framework. At home temperature, cadmium sulfide may possibly crystallize both inside the zinc blende or Crystal wurtzite framework. Alumina also has two probable buildings at area temperature, α-alumina (corundum) and β-alumina. Other binary crystals show distinct constructions at unique temperatures. Among the many most complex crystals are those of silicon dioxide (SiO2), which has seven distinctive structures at many temperatures and pressures; the commonest of such constructions is quartz.
